Special Issue Information

Dear Colleagues,

We are delighted to invite researchers to contribute to the Special Issue on “Plant Stress Biology”. This initiative seeks to advance our understanding of how plants perceive, respond to, and recover from diverse environmental and biotic stresses, which are escalating due to climate change, land degradation, and pathogen evolution.

Plant stress biology is a critical frontier in ensuring food security and ecological sustainability. This issue will highlight cutting-edge research on abiotic stresses (e.g., drought, salinity, extreme temperatures, heavy metals) and biotic challenges (e.g., pathogens, pests, invasive species), with a focus on molecular, physiological, and ecological mechanisms. Submissions may explore topics such as stress-signaling networks, epigenetic regulation, genome editing (e.g., CRISPR-based resilience engineering), microbiome interactions, and innovative phenotyping technologies. We particularly welcome studies integrating multi-omics approaches or synthetic biology to decode plant stress responses.

Join us in shaping a resilient future—submit your groundbreaking work and collaborate to turn stress biology insights into transformative tools for agriculture and ecosystems worldwide.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The cytokinin response regulator (ARR) gene is essential for cytokinin signal transduction, which plays a crucial role in plant growth and development. However, the functional mechanism of ARR genes in cotton leaf abscission remains incompletely understood. In this study, a total of 86 ARR genes were identified within the genome of Gossypium hirsutum. These genes were categorized into four distinct groups based on their phylogenetic characteristics, supported by analyses of gene structures and conserved protein motifs. The GhARR genes exhibited an uneven distribution across 25 chromosomes, with three pairs of tandem duplication events observed. Both segmental and tandem duplication events significantly contributed to the expansion of the ARR gene family. Furthermore, numerous putative cis-elements were identified in the promoter regions, with hormone and stress-related elements being common among all 86 GhARRs. Transcriptome expression profiling screening results demonstrated that GhARRs may play a mediating role in cotton’s response to TDZ (thidiazuron). The functional validation of GhARR16, GhARR43, and GhARR85 using virus-induced gene silencing (VIGS) technology demonstrated that the silencing of these genes led to pronounced leaf wilting and chlorosis in plants, accompanied by a substantial decrease in petiole fracture force. Overall, our study represents a comprehensive analysis of the G. hirsutum ARR gene family, revealing their potential roles in leaf abscission regulation. Full article
