Summary: In this study, a bZIP protein PtrbZIP3 was characterized in Populus trichocarpa, which showed significantly induced expression under various abiotic stress conditions. PtrbZIP3 functions as a transcriptional activator by specifically binding to ABRE and regulating the expression of ABA-dependent genes. Overexpression of PtrbZIP3 improves osmotic tolerance in P. trichocarpa by enhancing antioxidant enzyme activities, maintaining cell membrane integrity, reducing stomatal apertures and water loss, and increasing proline accumulation.

Summary: BES1 is an important transcription factor involved in regulating plant growth and stress resistance in plants. While its regulatory mechanism has been well studied in several plant species, the genome-wide analysis of BES1 in Vitis vinifera has not been comprehensively conducted. In this study, we identified and analyzed the BES1 transcription factor family in V. vinifera, including predicting eight VvBES1 genes, analyzing their phylogenetic relationships, gene structures, and promoter cis-acting elements. The results showed that VvBES1 genes were divided into three groups, with most genes belonging to group III, and they were located on seven chromosomes. In addition, the expression patterns of VvBES1 varied in different organs and under stress conditions, indicating a potential role in stress response. These findings provide a foundation for further functional validation of VvBES1 and offer insights for molecular breeding in V. vinifera.

Summary: In this study, the crucial roles of BES1 genes in abiotic stress responses and anther development in wheat were investigated. Most TaBES1-like genes were downregulated under abiotic stress, especially during drought stress. The expression patterns of TaBES1 genes in drought-tolerant and drought-sensitive cultivars suggest their involvement in regulating drought tolerance and low temperature-induced male sterility.

Summary: In this study, a genome-wide association study (GWAS) was conducted on 8 traits of 150 cotton germplasms using resequencing data. The results showed that 18 SNPs were significantly correlated with cotton yield traits under drought conditions, while 8 SNPs were significantly correlated with the traits related to yield. Transcriptome data analysis identified four highly expressed genes after drought stress. qRT-PCR confirmed that these genes had the same expression pattern in samples with extreme drought tolerance. This study provides a theoretical basis for genetic analysis and breeding improvement of cotton yield traits under drought stress.

Summary: Rice is an important staple food crop, but its yield is affected by drought. Through screening a set of mutants of a drought tolerant rice cultivar, it was found that some mutants showed higher or lower drought sensitivity scores than the wild type. These mutants also showed changes in epidermal wax content and various physiological traits related to drought tolerance. This discovery provides insights into drought tolerance mechanisms and gene discovery for breeding drought tolerant rice cultivars.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: This study identified the high nitrogen use efficiency (NUE) black sesame variety 17-156 and analyzed its underlying physiological and molecular mechanisms. The results showed that 17-156 possesses a sophisticated nitrogen metabolizing machinery to uptake and assimilate higher quantities of inorganic nitrogen, simultaneously improving carbon metabolism and growth. Many important genes were up-regulated in 17-156 under high nitrogen condition. Additionally, 38 potential candidate genes were identified for future studies to improve sesame's NUE. These findings provide valuable resources for understanding the regulatory network of nitrogen metabolism and developing sesame cultivars with improved NUE.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
