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.
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.
Transcriptional Regulation of Starch Biosynthesis in Sorghum: Functional Characterization of the B3 Transcription Factor SbLAV1
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.
Monolignol Pathway-Mediated Resistance to Sugarcane Aphid in Sorghum
Overexpression of the monolignol pathway gene SbCCoAOMT enhances sorghum resistance to sugarcane aphid through increased lignin deposition, altered phloem-feeding behavior, and accumulation of defensive phenolic compounds.
