Summary: In this study, a transcription factor called NtDREB-1BL1 was found to regulate carotenoid biosynthesis by binding to the NtPSY promoter in tobacco plants. Overexpression of NtDREB-1BL1 increased carotenoid and chlorophyll contents, while RNA interference of NtDREB-1BL1 decreased these contents. Additionally, NtDREB-1BL1 overexpression enhanced drought tolerance, whereas RNA interference weakened drought tolerance. These findings highlight the importance of NtDREB-1BL1 in regulating carotenoid biosynthesis and improving drought tolerance in tobacco.

Summary: The study identified a novel heat shock transcription factor gene, ZmHsf08, in maize, which negatively regulates responses to salt and drought stresses in the plant. Overexpression of ZmHsf08 resulted in increased sensitivity to salt and drought stresses, with higher ROS levels and MDA contents compared to wild-type plants. Analysis also showed that ZmHsf08 negatively regulates stress/ABA-responsive genes under salt and drought stress conditions.

Summary: Soil salination can lead to reduced crop production globally. This study focused on annual ryegrass and conducted a comparative transcriptome analysis to identify the core genes involved in the early responses to salt stress. The findings revealed that differences in lipid, vitamins, and carbohydrate metabolism contribute to the variation in salt tolerance between salinity-sensitive and salinity-insensitive genotypes. The study also discovered novel regulation mechanisms related to salinity stress sensing, phytohormones signaling transduction, and transcriptional regulation of the early salinity responses. Overall, this research provides insights into the mechanisms of the early salinity response in annual ryegrass and can aid in the breeding of salt-tolerant forage.

Summary: The study conducted a comprehensive analysis of the DgbHLH family in orchardgrass, identifying 132 DgbHLH genes and classifying them into 22 subfamilies. Various analyses including gene structure, conserved motifs, chromosomal location, and gene duplication events were performed to support the classification. Transcriptome data revealed differential expression of DgbHLH genes in different tissues and under different abiotic stress conditions. Heterologous expression assays in yeast indicated that DgbHLH46 and DgbHLH128 may enhance resistance to drought and salt stress, with DgbHLH128 potentially being involved in abiotic stress response by binding to the MYC element. This study provides valuable insights for gene utilization and improvement of forage performance in orchardgrass.

Summary: In this study, the miRNA expression profiles of perennial ryegrass were analyzed to uncover the regulatory mechanisms involved in heat tolerance mediated by exogenously applied methyl jasmonate (MeJA). The results showed that 102 miRNAs were up-regulated in all treatments, with different numbers of miRNAs being up-regulated in the MeJA pre-treatment, heat stress treatment, and MeJA pre-treatment + heat stress groups. Co-expression network analysis revealed that 20 miRNAs modulated 51 potential target genes, with specific pathways related to heat tolerance being influenced by MeJA. Overall, this research provides a foundation for further understanding the heat tolerance mechanism in perennial ryegrass and developing cultivars with enhanced heat tolerance.
