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.
This review highlights how cereal-specific meristems, such as those in sorghum, contribute to complex plant architectures and offer new targets for crop improvement through advanced genomic tools.
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.
SbLAV1, a member of the B3 transcription factor family in sorghum, plays a key regulatory role in starch biosynthesis during grain development through transcriptional activation of starch biosynthesis-related genes.
Overexpression of the sorghum transcription factor SbNAC074 enhances plant salt tolerance by promoting proline accumulation, boosting antioxidant enzyme activity, and interacting with SbMPK3 for phosphorylation-mediated regulation.
Mishra et al. used multi-omics analysis in sorghum to reveal conserved gene networks and regulatory mechanisms underlying iron and zinc homeostasis, linking root uptake and leaf chloroplast function under micronutrient stress.
Sorghum seed coat color correlates with the accumulation of phenolic and volatile compounds, and key regulatory genes including ABCB28, PTCD1, and ANK have been identified as central to their biosynthesis and transport.
Ding et al. identified SbC1, an R2R3-MYB transcription factor, as a key regulator of anthocyanin biosynthesis in sorghum coleoptiles, highlighting its role in pigmentation, stress tolerance, and potential applications in crop improvement.
