Special Issue Information

Dear Colleagues,

As global challenges like climate change and food security become more pressing, understanding how plants resist biotic and abiotic stresses is increasingly important. Plants, as sessile organisms, face constant exposure to various stresses, including pathogens, pests, drought, salinity, and extreme temperatures. Recent advancements in genomics, phenomics, and molecular biology have revealed the complex mechanisms that underlie plant stress responses. For this Special Issue, we invite you to submit research papers that explore the genetic, molecular, and physiological aspects of plant resistance to both biotic and abiotic stresses. We encourage submissions that focus on novel resistance genes, signaling pathways, and the role of secondary metabolites. Additionally, studies examining the interactions between environmental factors and plant defense responses, along with their underlying molecular mechanisms, are highly welcome. Our goal is to create a collaborative platform for the plant research community to share innovative strategies, methodologies, and groundbreaking findings related to plant resilience. We warmly welcome original research articles and comprehensive reviews that enhance our understanding of plant resistance in the face of environmental challenges.

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.

Homology to E6-AP Carboxy Terminus (HECT) E3 ubiquitin ligases play pivotal roles in plant growth, development, and responses to abiotic stresses. However, the function of HECT genes in Phyllostachys edulis (P. edulis) remains largely uninvestigated. In this study, a comprehensive genome-wide analysis of the HECT E3 ubiquitin ligases gene family in P. edulis was conducted, aiming to elucidate its evolutionary relationships and gene expansion. Analysis of gene structure, conserved motifs and domains, and synteny genome regions were performed. Furthermore, cis-elements in HECT gene promoters that respond to plant hormones and environmental stresses were identified and corroborated by expression data from diverse abiotic stress conditions and hormone treatments. Based on the co-expression network of PeHECTs under cold and dehydration stresses, PeHECT1 was identified as a key candidate gene associated with abiotic stress tolerance. Overexpression of PeHECT1 in tobacco leaves significantly upregulated genes related to reactive oxygen species (ROS) detoxification and polyamine biosynthesis. Yeast one-hybrid (Y1H), electrophoretic mobility shift assay (EMSA), and dual-luciferase (dual-LUC) assays suggested that the transcription factor ETHYLENE RESPONSE FACTOR 3 (PeERF3) bound to the dehydration-responsive element (DRE) of the promoter of PeHECT1 and activated its transcription activity. Phylogenetic analysis indicated that PeHECT1 in P. edulis exhibited a close association with the diploid herbaceous bamboo Olyra latifolia, followed by the divergence of rice and bamboo. In summary, this study enhances our comprehensive understanding of the HECT E3 ubiquitin ligases gene family in P. edulis and highlights the potential role of PeHECT1 in plant abiotic stress response.
