Drought severely limits crop yield every year, making it critical to clarify the genetic basis of drought tolerance for breeding of improved varieties. As drought tolerance is a complex quantitative trait, we analyzed three phenotypic groups: (1) agronomic traits under well-watered (WW) and water-deficit (WD) conditions, (2) stress tolerance indices of these traits, and (3) phenotypic plasticity, using a multi-parent doubled haploid (DH) population assessed in multi-environment trials. Genome-wide association studies (GWAS) identified 130, 171, and 71 quantitative trait loci (QTL) for the three groups of phenotypes, respectively. Only one QTL was shared among all trait groups, 25 between stress indices and agronomic traits, while the majority of QTL were specific to their group. Functional annotation of candidate genes revealed distinct pathways of the three phenotypic groups. Candidate genes under WD conditions were enriched for stress response and epigenetic regulation, while under WW conditions for protein synthesis and transport, RNA metabolism, and developmental regulation. Stress tolerance indices were enriched for transport of amino/organic acids, epigenetic regulation, and stress response, whereas plasticity showed enrichment for environmental adaptability. Transcriptome analysis of 26 potential candidate genes showed tissue-specific drought responses in leaves, ears, and tassels. Collectively, these results indicated both shared and independent genetic mechanisms underlying drought tolerance, providing novel insights into the complex phenotypes related to drought tolerance and guiding further strategies for molecular breeding in maize.

In this article, we examine the theoretical concept of hybrid masculinities from a praxeological perspective, focusing on fathers as caring parents. Examining the development of parenting practices and parental knowledge exchange, we conducted couple interviews with 42 couples (n = 42, 2021 and 2022) and analyzed how fathers’ and couples’ motivations for sharing parental leave (PL) and childcare allowance (CA) in Austria shape fatherhood practices. All interviewees had claimed CA for a minimum duration of five months. Since infant care has only recently been incorporated into normative constructions of masculinity, our praxeological analysis centers on fathers. By applying the theoretical concept of hybrid masculinities, we examine these practices which are still perceived as “new”. In the couple interviews we conducted, we analyzed the reports and views of both parents, which tended to be more fully expressed when the parents interviewed were in conversation with each other. We applied topic-specific content analysis and Informed Grounded Theory to analyze the empirical data, guided by semi-structured interview protocols and coded with MAXQDA. Our findings indicate that fathers successfully take on and embody caregiving responsibilities. However, they also continue to conform to traditional constructions of masculinity, particularly in their long-term reconciliation of childcare and employment. Considering international PL and CA policies, we discuss the relationship between parents’ dual PL uptake and social sustainability in the transformation of gendered parenting norms and the reduction in gender inequalities.

People with intellectual disability want friendships and meaningful relationships, and some want intimacy. However, the expression of sexuality is an area where potential freedoms are often limited and restricted compared to their peers. While some relationships and sexuality education programmes do exist for this population, most focus on knowledge acquisition regarding sexuality and sex but lack in their focus on relationships, informed choices and decision-making. The aim of this study was to identify good practices and methods of delivery in relationships and sexuality education for children and young people with intellectual disability. A qualitative design was undertaken. Information about our study was distributed to eight special schools in the UK. Semi-structured interviews and focus groups were employed for data collection. Data from 37 pupils with intellectual disability, 11 parents and 16 healthcare and other professionals were thematically analysed. Following data analysis, three themes emerged: (i) seeking and sharing information; (ii) protecting and keeping safe; and (iii) learning for the future. The findings highlight that pupils are keen to learn about life changes and societal influences and want reliable information. Parents and professionals recognise that children and young people with intellectual disability will develop into adults and may be vulnerable when they leave the security of the school setting. They recognise that children and young people need to know about socialising, puberty, consent and contraception. Evidence-based programmes should be designed with these stakeholders to ensure children and young people with intellectual disability receive developmentally appropriate information to make happy and safe decisions about their relationships.

In recent decades, several countries have implemented paid parental leave for parents. This paper discusses the correlation between paid parental leave—which in Austria corresponds with receiving childcare benefits—and changing gender role attitudes in different-gender parent couples. It draws on evidence from 42 semi-structured couple interviews (n = 42, 2021–2022) in which couples were asked how they arranged childcare, employment, and household chores and how they reached agreements with employers. The empirical data were first analyzed based on content and then by applying constructivist-informed grounded theory to investigate whether and how gender affected couples’ efforts to reconcile childcare, employment, and household chores and how employers responded to parental arrangements that challenged traditional gender role attitudes. Compared to other countries, Austria offers rather generous childcare benefits, including long leave periods. In addition, Austria has introduced a partnership bonus for parents who share childcare benefits 50:50 or 60:40. However, the number of couples who take advantage of these benefits is still low. In the presented research, parents who succeeded in sharing these childcare benefits were interviewed. All interviewees had taken at least five months of paid parental leave. The data were analyzed using a content-oriented approach and by applying informed grounded theory. The results show that a substantial number of fathers continued working in minor employment while receiving childcare benefits, in line with the prevailing assumption among employers that the man is the main family breadwinner. By contrast, mothers had to strongly insist that they could continue working during the early transition to parenthood. However, on an individual level and in specific domains, Austrian parents were able to successfully overcome traditional gender inequalities in reconciling work and family with the support of the newly implemented childcare benefits. The observation that in Austria, the share of fathers who take the income-related form of parental leave is higher than that of fathers who claim other forms of childcare benefits points to the importance of all parents having access to well-compensated parental leave, regardless of their income level before the birth of a child.

Oilseed rape (Brassica napus L.) is an important cash crop, but transgenic oilseed rape has not been grown on a commercial scale in China. It is necessary to analyze the characteristics of transgenic oilseed rape before commercial cultivation. In our study, differential expression of total protein from the leaves in two transgenic lines of oilseed rape expressing foreign Bt Cry1Ac insecticidal toxin and their non-transgenic parent plant was analyzed using a proteomic approach. Only shared changes in both of the two transgenic lines were calculated. Fourteen differential protein spots were analyzed and identified, namely, eleven upregulated expressed protein spots and three downregulated protein spots. These proteins are involved in photosynthesis, transporter function, metabolism, protein synthesis, and cell growth and differentiation. The changes of these protein spots in transgenic oilseed rape may be attributable to the insertion of the foreign transgenes. However, the transgenic manipulation might not necessarily cause significant change in proteomes of the oilseed rape. Full article

Paternal mental health continues to be a health concern in the UK. Paternal leave entitlement and workplace cultures have failed to support fathers in navigating the complexity of fatherhood, which has an impact on fathers’ wellbeing. Interviewing twenty fathers in the York area, this study seeks to explore the impact of parental leave entitlements and workplace cultures on fathers’ mental health. The findings demonstrate that the influence of gendered norms and hegemonic masculinity perceptions are ingrained in the current leave entitlement and workplace cultures. While fathers are entitled to take leave, the leave is significantly insufficient to allow them to forge a meaningful bond with a newborn or adapt to the change in routine brought about by the birth of a baby. Furthermore, workplace cultures fail to recognise the responsibilities that come with fatherhood and provide insufficient support for fathers. The COVID-19 lockdown presented fathers with a unique opportunity to be available and take on more family responsibilities. Fathers felt they did not have to navigate gendered and hegemonic perceptions to spend more time with the family. This paper challenges structural and cultural barriers that prevent fathers from taking leave and impacting negatively on fathers’ mental health. The paper suggests a review of the current paternal leave entitlement and cultural change in the workplace. Full article

To date, PHMR has often relied on male/female stratification, but rarely considers the complex, intersecting social positions of men and women in describing the prevalence of health and disease. Stratification on an Intersectional Gender-Score (IG-Score), which is based on a variety of social covariables, would allow comparison of the prevalence of individuals who share the same complex intersectional profile (IG-Score). The cross-sectional case study was based on the German Socio-Economic Panel 2017 (n = 23,269 age 18+). After stratification, covariable-balance within the total sample and IG-Score-subgroups was assessed by standardized mean differences. Prevalence of self-rated health, mental distress, depression and hypertension was compared in men and women. In the IG-Score-subgroup with highest proportion of males and lowest probability of falling into the ‘woman’-category, most individuals were in full-time employment. The IG-Score-subgroup with highest proportion of women and highest probability of falling into the ‘woman’-category was characterized by part-time/occasional employment, housewife/-husband, and maternity/parental leave. Gender differences in prevalence of health indicators remained within the male-dominated IG-Score-subgroup, whereas the same prevalence of depression and self-rated health was observed for men and women constituting the female-dominated IG-Score-subgroup. These results might indicate that sex/gender differences of depression and self-rated health could be interpreted against the background of gender associated processes. In summary, the proposed procedure allows comparison of prevalence of health indicators conditional on men and women sharing the same complex intersectional profile. Full article

Societies’ ideologies on the distribution of unpaid labour seem to have remained stagnant despite dramatic shifts in the worlds of work and society. The distribution of unpaid labour has implications for the wellbeing of individuals and the sustainability of their various personal and professional relationships. Our study addressed the less-researched “what” and “why” of the distribution of unpaid labour among dual-earner couples during the COVID-19 pandemic. We used a qualitative approach, conducting 32 semi-structured interviews with individuals belonging to dual-earner couples in Sri Lanka. Interview data were thematically analysed using social role theory. Six major findings emanated from our study; (1) the pandemic did not drastically change the distribution of unpaid labour in most dual-earner couples, confirming traditional gender norms; (2) there was a change in the contribution of men towards unpaid labour when the woman was at home (working from home or during maternity leave), or had other means of support from domestic aid or extended family; (3) three clusters of men were identified as “sharing”, “chipping-in”, and “not-my-problem” types, depending on their involvement in unpaid labour; (4) “chipping-in” and “not-my-problem” type men reinforced the notion of gendered distribution of unpaid labour; (5) three clusters of women were identified as “sharing”, “asking-for-help”, and “bearing-the-cross” types; and (6) these couples, and women specifically, endured the unequal division of unpaid labour with the assistance of parents, in-laws, or paid domestic help. Our study has implications for the sustainability of individuals, as well as their wellbeing, families, organisations, and society. Full article

The non-volatile and volatile metabolites in tea confer the taste and odor characteristics of tea fusion, as well as shape the chemical base for tea quality. To date, it remains largely elusive whether there are metabolic crosstalks among non-volatile metabolites and volatile metabolites in the tea tree. Here, we generated an F1 half-sib population by using an albino cultivar of Camellia sinensis cv Baijiguan as the maternal parent, and then we quantified the non-volatile metabolites and volatile metabolites from individual half-sibs. We found that the EGC and EGCG contents of the albino half-sibs were significantly lower than those of the green half-sibs, while no significant differences were observed in total amino acids, caffeine, and other catechin types between these two groups. The phenylpropanoid pathway and the MEP pathway are the dominant routes for volatile synthesis in fresh tea leaves, followed by the MVA pathway and the fatty acid-derivative pathway. The total volatile contents derived from individual pathways showed large variations among half-sibs, there were no significant differences between the albino half-sibs and the green half-sibs. We performed a comprehensive correlation analysis, including correlations among non-volatile metabolites, between volatile synthesis pathways and non-volatile metabolites, and among the volatiles derived from same synthesis pathway, and we identified several significant positive or negative correlations. Our data suggest that the synthesis of non-volatile and volatile metabolites is potentially connected through shared intermediates; feedback inhibition, activation, or competition for common intermediates among branched pathways may co-exist; and cross-pathway activation or inhibition, as well as metabolome channeling, were also implicated. These multiple metabolic regulation modes could provide metabolic plasticity to direct carbon flux and lead to diverse metabolome among Baijiguan half-sibs. This study provides an essential knowledge base for rational tea germplasm improvements. Full article

Purpose: The COVID-19 pandemic has drastically impacted everyday life. Not only has it assailed the world’s populations with millions of deaths and cases, but COVID-19 has also ravaged global economies and affected the lives of women and their children. The purpose of this study was to detail women’s experiences during the COVID-19 pandemic and the solutions they came up with to deal with the problems they encountered. Method: Data collection occurred in the midwestern United States, in the State of Indiana, from August 2020 to August 2021. Sixty-six women participated in the study. The study used open-ended survey questions. The data results were combined, analyzed, and constructed into themes based on their similarity in their subject matter. The researchers identified four main themes. Findings and Conclusion: Results indicated that, for some of the mothers, it was a struggle to be at home with their children at all times. Unique experiences faced by some expectant mothers who were already mothers, and thus had the experience of prenatal care pre-COVID-19, had to grapple with the fact that they were not allowed to come to their prenatal appointments with anyone. Participants complained about cooking all the time, with some needing to use the internet to look for new recipes. Poor eating habits by some children during the pandemic led to some parents needing to come up with a schedule for family members regarding breakfast, lunch, dinner, and snacks to curtail the COVID-19-related acquired poor eating habits. A shared experience from the study revolved around childcare policies and schedules. The results suggested that enacting a paid childcare leave, developing flexible working hours, and changing how employers conduct work reviews are critical to alleviating some of the burdens working women face during school closures during the pandemic. Finally, participants suggested identifying better ways to provide and prioritize childcare to lessen gender inequalities within the workforce. Full article

Even though smoking causes numerous threats to the developing foetus, it is the most common addiction in Polish women of reproductive age. Most studies undertake to examine the subject of opposing second-hand smoking or creating tools to reprimand pregnant women more effectively using a qualitative methodology. The study aimed to determine the profile of a pregnant woman who is willing to oppose the smoking of another pregnant woman. The research was conducted using an original multiple-choice questionnaire. The survey was shared on websites for expecting parents. Completed questionnaires were collected from 11,448 pregnant women. The Wald test for logistic regression was used for statistical analysis. Predictors of whether someone would draw another pregnant women’s attention to the fact that smoking is harmful were: intellectual work (OR 1.136; p-value 0.020) and currently being a student (OR 1.363; p-value 0.004), involvement of the child’s father (OR 1.377; p-value < 0.001), contact with social campaigns (OR 1.150; p-value 0.005) and knowledge about the consequences of smoking, as well as talking to the midwife about the harmfulness of cigarettes during pregnancy (OR 1.655; p-value < 0.001). Interpersonal relationships leave scope for public health interventions. It is worth enhancing criticism against smoking by specialists through information and education campaigns. Full article

This study examines the impact of work-life balance (WLB) practices concerning academics’ turnover intention, person-job fit (PJF), and PJF’s relationship with academics’ intention to leave their jobs. The study further investigates person-job fit as an underlying mechanism of the association between WLB practices and turnover intention. The study’s data were collected through a self-administered questionnaire garnered from 550 full-time academics working in higher educational institutions in South India (Andhra Pradesh, Karnataka, Kerala, Tamil Nadu, and Telangana, as well as the union territories of Lakshadweep and Puducherry). Partial least squares structural equation modelling (PLS-SEM) was employed for the statistical analysis of the data, using Smart PLS 3.2.8 software. The study ascertained that WLB practices have a negative impact on academics’ turnover intention. Additionally, the study discovered that WLB practices have a positive impact on PJF. Similarly, PJF seems to have a significant negative influence on turnover intention. Moreover, PJF partially and negatively mediates the influence of WLB practices on turnover intention. Consequently, this study suggests implementing several WLB practices (e.g., telecommuting, job sharing, flexitime, paid parental leave, etc.) into higher educational institutions, since it may not only improve academics’ perception of their person-job fit but it may also reduce their turnover intention.

This paper, which is based on qualitative research conducted in Austria, focuses on current gender inequalities between parents in fulfilling their parental responsibilities, which means reconciling the responsibilities of childcare and earning a living. Austria is characterized by a substantial gender gap in men’s and women’s labor force participation and a system that provides particularly long parental leaves. These foster long-term gender inequalities in parents’ careers and involvement in family life after their transition to parenthood. Against this background, we analyzed constructions of parental responsibilities parents face at their workplaces, and how these constructions shape parents’ decisions on sharing parental responsibilities. The findings demonstrate the relevance of parental norms that comprise a father’s main responsibility as breadwinner and a mother’s primary responsibility as a caregiver, constructed and reproduced by parents’ colleagues and employers. Consequently, for parents who try to share their breadwinning and caregiving in a non-normative (and more gender-equal) way, both parents are forced to find strategies in dealing with normative constructions. These strategies range from making a ‘conscious decision’, insisting on the original plan, and challenging predominant norms at workplaces, through quitting the job and looking for another employer, to modifying or giving up the originally planned arrangement.

Parental leaves are, besides unemployment, the main reason for career breaks in early career. Despite the progress in recent decades towards more equal sharing of childcare between mothers and fathers, the labour market risk due to parenting remains mainly with women. In this article, we analyse how parental leaves relate to early career trajectories of young Finnish men and women. Using longitudinal register data for 2005–2016 from the Finnish Centre for Pensions, we perform a multi-trajectory analysis of the labour market attachment of a cohort born in 1980. Based on working days and earnings, we find five distinct career trajectories for both men and women, with the majority being well attached to the labour market by their mid-30s. While men and women on average have similar employment lengths, the gender gap in earnings is already 30 per cent in this early career phase. One of the causes may be found in the highly unequal division of family-related career breaks; the duration of mothers’ family-related leaves in this cohort was 13 times longer than fathers’ leave spells. Long home care leaves were particularly common among mothers with low education levels and weak attachment to the labour market. Efforts towards a more equal division of parental leaves are needed in order to combat gender inequalities that already emerge in early career and potentially cause life-long disadvantages for women’s careers, earnings and pensions.

Precise and timely regulation of organ separation from the parent plant (abscission) is consequential to improvement of crop productivity as it influences both the timing of harvest and fruit quality. Abscission is tightly associated with plant fitness as unwanted organs (petals, sepals, filaments) are shed after fertilization while seeds, fruits, and leaves are cast off as means of reproductive success or in response to abiotic/biotic stresses. Floral organ abscission in Arabidopsis has been a useful model to elucidate the molecular mechanisms that underlie the separation processes, and multiple abscission signals associated with the activation and downstream pathways have been uncovered. Concomitantly, large-scale analyses of omics studies in diverse abscission systems of various plants have added valuable insights into the abscission process. The results suggest that there are common molecular events linked to the biosynthesis of a new extracellular matrix as well as cell wall disassembly. Comparative analysis between Arabidopsis and soybean abscission systems has revealed shared and yet disparate regulatory modules that affect the separation processes. In this review, we discuss our current understanding of the transcriptional regulation of abscission in several different plants that has improved on the previously proposed four-phased model of organ separation.
