Identification, Evolutionary Analysis, and Stress-Responsive Roles of the Dirigent (DIR) Gene Family in Sorghum bicolor

Liu et al. systematically identified and characterized 53 DIR genes in Sorghum bicolor, revealing their evolutionary diversification, tissue-specific expression, and key roles in lignin biosynthesis and abiotic stress tolerance, with SbDIR39 and SbDIR53 highlighted as promising targets for crop improvement.

Uncovering Novel Regulators of Flowering Time in Temperate-Adapted Sorghum Through Integrated Genomic and Transcriptomic Analyses

Researchers identified novel genetic regulators of flowering time in temperate-adapted, photoperiod-insensitive sorghum using expanded genome-wide and transcriptome-wide association analyses, revealing key roles for FT, MADS-box, and ageing pathway genes beyond the classical maturity loci.

Genotypic Regulation of Drought-Induced Cyanogenesis in Sorghum: Insights into Dhurrin Biosynthesis and Stress Adaptation Mechanisms

Katamreddy et al., revealed that drought-induced hydrogen cyanide (HCN) accumulation in sorghum is regulated by genotype-specific differences in dhurrin biosynthesis, membrane stability, and transcription factor networks, offering targets for developing safer, drought-tolerant forage varieties.
