Summary: In this study, 35 Lhcb genes (BnLhcbs) were identified in the rapeseed genome, which play essential roles in photosynthesis and stress response. The BnLhcb3.4 gene was significantly induced in the tolerant rapeseed cultivar and down-regulated in the sensitive cultivar. Overexpression of BnLhcb3.4 gene enhanced the freezing tolerance of transgenic Arabidopsis and altered the expression of ABA-responsive genes.

Summary: Editing AITR genes using CRISPR/Cas9 enhances plant stress tolerance without fitness costs. Knocking out AITR family genes improves plant resilience to abiotic stresses, with sextuple mutants showing normal growth and response to pathogens. AITRs may be targeted for molecular breeding to enhance stress tolerance in various plants, including crops.

Summary: Phytohormones are crucial in regulating plant growth, development, and stress responses globally. They play important roles in the transcriptional regulation of stress-responsive genes and metabolic adjustment. The balance between growth promotion and stress resistance is maintained through the coordinated action of phytohormones.

Summary: In this study, the function of BcWRKY33A in salt stress response in non-heading Chinese cabbage was investigated. BcWRKY33A was found to enhance salt tolerance in Arabidopsis and interact with BcHSFA4A. The regulatory interaction between BcWRKY33A and BcHSFA4A promotes the expression of salt-related genes and improves salt tolerance in plants. These findings provide insights into the molecular mechanism of salt tolerance in plants.

Summary: In this study, we identified and characterized 47 BpbZIP genes in the silver birch genome. The BpbZIP proteins clustered into 10 groups in phylogeny based on the bZIP classification for Arabidopsis thaliana. We found that BpbZIP genes were widely involved in abscisic acid, salt, drought, and heat stress responses, with BpbZIP07/ABF4 and BpbZIP21/ABF2 being the most highly expressed.

Summary: Environmental stresses like drought, high salinity, and low temperature can negatively affect field crops by altering their morphology, physiology, and biochemistry. Plants can survive these stresses through management practices and adaptive mechanisms. Recent studies have shown that zinc finger motifs play a crucial role in the abiotic stress response in plants.

Summary: This study identified the potential genes associated with salt tolerance in S. drummondii through transcriptome profiling, highlighting the induction of certain genes in shoot and root tissues as a key factor in salt tolerance. These findings were validated through reverse-transcription quantitative PCR, providing valuable genetic information on salt tolerance mechanisms in S. drummondii.

Summary: Suberin, a complex polyester, plays a role in controlling the movement of water, ions, and gas in the seed coat outer integument. This study investigated the role of the plant hormone abscisic acid (ABA) in suberin layer formation during seed coat development. The results showed that ABA is important for regulating the permeability of the seed coat.

Summary: The plant-specific SCL30a SR protein negatively regulates ABA signaling to control seed traits and stress responses during germination in Arabidopsis. Loss of SCL30a function induces ABA-responsive gene expression and genes repressed during germination, resulting in delayed germination and hypersensitivity to ABA and high salinity in scl30a mutant seeds. Transgenic plants overexpressing SCL30a exhibit reduced ABA and salt stress sensitivity.

Summary: Abscisic acid (ABA) is an important hormone in plants that regulates growth and development, with PYL proteins playing a central role in signal transduction pathways. In cucumber, 14 PYL genes were identified, showing specific expression patterns in response to different stresses. Some genes, like PYL8, may have a crucial role in abiotic stress responses.

Summary: The ABA signaling pathway plays a vital role in abiotic stress response and development in chickpea. Through gene identification, protein modeling, and gene expression analysis, key genes involved in this pathway were identified and their overlapping roles in drought, ABA response, and seed development were revealed. In-silico interaction analysis also showed the functional relevance of these proteins. Overall, understanding the core components of the ABA signaling pathway in chickpea provides valuable insights for breeding stress-tolerant and high-yielding varieties.

Summary: The study demonstrated that the anti-stress function of AtPDI1 in Arabidopsis is directly related to its disulfide isomerase activity. Mutant plants with altered cysteine residues showed significantly lower germination rates under stress conditions compared to wild-type and overexpressing lines. The transcriptional levels of stress-responsive genes were also lower in the mutant plants, indicating the importance of AtPDI1 in stress response.
