Special Issue Information

Dear Colleagues,

Horticultural plants, encompassing fruits, vegetables, ornamentals, tea, and nuts, play a crucial role in global food security, nutrition, and aesthetics. As climate change and environmental stressors increasingly affect agricultural productivity, it is essential to deepen our understanding of the molecular mechanisms underlying stress responses in these valuable crops.

We are pleased to announce a Special Issue titled "Molecular Biology for Stress Management in Horticultural Plants." This initiative aims to gather and disseminate the latest advancements in the field, focusing on the intricate gene expression and regulatory networks that govern stress tolerance in horticultural plants.We cordially invite researchers to submit their work on the following topics:

  1. Identification and Functional Analysis of Key Genes: Studies that identify and characterize genes critical for stress tolerance in horticultural crops, elucidating their roles and mechanisms of action.
  2. Transcriptional and Post-transcriptional Regulatory Networks: Research that explores the complex networks regulating gene expression at both transcriptional and post-transcriptional levels, including the involvement of non-coding RNAs and regulatory proteins.
  3. Epigenetic Modifications: Investigations into the role of epigenetic modifications, such as DNA methylation, histone modification, and chromatin remodeling, in modulating gene expression under stress conditions.
  4. Omics Technologies: Applications of omics technologies (genomics, transcriptomics, proteomics, and metabolomics) to uncover novel regulatory pathways and integrative mechanisms that contribute to stress resilience in horticultural plants.

We welcome original research articles, comprehensive reviews, and insightful perspectives that provide valuable insights into the molecular foundations of stress management in horticultural plants. This Special Issue aims to compile a diverse array of high-quality studies to enhance our collective understanding of the mechanisms regulating gene expression and stress responses in these plants. Ultimately, we hope this collection will serve as a valuable reference for breeding strategies and sustainable agricultural practices, contributing to the resilience and productivity of horticultural crops in the face of environmental challenges.

We look forward to receiving your contributions and collaborating to advance the field of molecular biology in horticultural stress management.

This study conducted a genome-wide identification and systematic evolutionary analysis of the banana WRKY gene family using bioinformatics, transcriptomics, and molecular biology approaches. A total of 153 WRKY genes were identified in the banana genome, with significant differences in the amino acid count, molecular weight, and other physicochemical properties of their encoded proteins. The subcellular localization of these proteins is primarily in the nucleus. These genes are unevenly distributed across 11 chromosomes, with the highest density on chromosome 7. WRKY gene family members exhibit diverse expression patterns during fruit development and ripening, and some can respond to multiple abiotic and biotic stresses. Systematic evolutionary analysis classified them into three major groups (I, II, and III), with Group II having the highest number of members, which are further divided into five subgroups. Conserved motif analysis revealed that Motif1, Motif2, and Motif4 are key structural elements in the family’s evolution, with some members having a WRKYGKK variant. The gene structure shows a wide range of exon numbers (1–22), and the promoter regions are rich in cis-elements related to light response, hormone signaling, and stress response, indicating their potential for integrating light signals, hormone networks, and multiple stress responses. Collinearity analysis identified 116 segmental duplication events, with Ka/Ks values all less than 1, indicating purifying selection. After ethylene treatment, 51 genes showed significant changes in expression, which can be categorized into four patterns: sustained upregulation, sustained downregulation, initial upregulation followed by downregulation, and delayed upregulation. Among these, MaWRKY10, MaWRKY88, and MaWRKY137 exhibited significant expression changes and may play key roles in fruit ripening. These findings significantly contribute to the theoretical framework regarding the evolution and function of the WRKY family in plants. Moreover, they offer valuable gene resources and regulatory strategies that enhance postharvest banana preservation and molecular breeding efforts. Full article
