This study elucidates the genetic architecture of sorghum plant height by characterizing major dwarfing genes (Dw1–Dw3), revealing their additive effects, allelic diversity, and the potential role of undiscovered minor-effect loci in shaping dwarf phenotypes.
Guard cell-specific expression of AtTOR enhances drought tolerance and water use efficiency in Arabidopsis by reducing transpirational water loss while maintaining or improving photosynthetic performance through modulation of stomatal function and ABA-related signaling pathways.
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.
