Special Issue Information

Dear Colleagues,

Global agricultural production has encountered numerous challenges arising from various biotic and abiotic environmental factors. Several crops have exhibited increased resilience after being subjected to treatments with signalling compounds, differential mineral nutrition, fungi, bacteria, and other exogenous interventions. Researching potential strategies to increase the resistance of plants to environmental changes is critical for enhancing crop productivity. Thus, we invite researchers and experts to contribute to this Special Issue with high-quality papers focusing on a comprehensive exploration of the theme “Mitigating Effect of Exogenous Treatments Against Stress in Plants”. Original research, reviews, and methodological papers that contribute to a better understanding of how exogenous treatments can mitigate environmental stresses in agricultural settings are welcome. Submissions will be peer-reviewed for their scientific rigor and potential impact on the field.

Searching for crop cultivars that are resilient to environmental stresses is crucial for maintaining global agricultural production. Our study aimed to screen semiarid-adapted cotton cultivars performing well under water-restricted conditions. Trials were conducted in a greenhouse involving six cotton cultivars (FM 911, FM 912, FM 970, FM 974, FM 978, and FM 985) subjected to four water levels (100, 80, 60, and 40% field capacity—FC). At 20 days post-drought imposition, the growth, leaf succulence, osmotic potential, gas exchanges, photosynthetic pigments, and lipid peroxidation were measured. Cotton plants showed reduced growth and gas exchanges at 60% and 40%, displaying elevated sensibility at 40% FC. Under 60% FC, FM 970 and FM 985 exhibited a superior dry biomass, leaf area, and growth, indicating high drought tolerance. FM 911, FM 912, and FM 978 displayed higher rates of net photosynthesis, transpiration, stomatal conductance, and chlorophyll content under 60% and 40% FC, but also demonstrated an increased lipid peroxidation. Additionally, FM 911, FM 970, and FM 974 had the lowest osmotic potential values. Field capacity at 60% and 40% represent moderate and severe drought conditions for cotton. The superior performance of FM 970, FM 978, and FM 985 under drought is attributed to pigment accumulation and photosynthetic efficiency. Our findings suggest that a water-saving strategy with an 80% FC can enhance sustainable production and identify promising cotton cultivars for cultivation in water-scarce regions. Full article

Ginger (Zingiber officinale Roscoe) is a significant medicinal and culinary plant, with its growth influenced by various biotic and abiotic factors. The FWL gene, containing the PLAC8 motif, is prevalent in fungi, algae, higher plants, and animals. In plants, FWL primarily regulates fruit weight, cell division, and participates in heavy metal transport. However, the FWL family members in ginger have not been previously identified. This study identified 21 FWL members within the ginger genome, distributed across nine chromosomes. These 21 FWL genes were categorized into five subfamilies based on the phylogenetic analysis. Gene-structure and motif analyses revealed that ZoFWL has been conserved throughout evolution. Concurrently, the ZoFWL gene exhibits a homologous evolutionary relationship only with Musa acuminata. We identified three pairs of fragment-repeat events encompassing five genes, which likely represent the primary mechanism for amplification within the ZoFWL gene family. The promoter regions of the ZoFWL genes are enriched with numerous cis-acting elements implicated in plant growth, development, and responses to abiotic stress. These include elements responsive to low temperatures, anaerobic induction, MYB binding sites integral to defense and stress responses, and drought inducibility. Expression profiling revealed that the ZoFWL genes are responsive to a quartet of abiotic stressors, with ZoFWL18, in particular, demonstrating a pronounced response to osmotic, low-temperature, heat, and salinity stresses. This underscores the pivotal role of ZoFWLs in abiotic-stress responses. Our findings offer valuable insights into the potential of the ZoFWL gene family in modulating ginger rhizome development and the genes’ response to abiotic stressors, laying a foundational framework for future research into ginger’s resistance breeding.
