Birhanu et al. identified key genetic loci associated with anthracnose resistance in Ethiopian sorghum germplasms, highlighting its potential as a valuable resource for breeding resistant sorghum varieties.
Liu et al. evaluated the low-nitrogen tolerance of 100 sorghum genotypes, identifying key morphological, photosynthetic, and metabolic traits that enhance nitrogen efficiency and improve adaptation to nutrient-limited environments.
This study reveals that while brassinosteroid receptors BRI1 and BRL3 both impact drought response, BRL3 promotes drought tolerance in sorghum through osmotic protection, whereas BRI1 signaling is associated with drought susceptibility due to growth-related sensitivities.
Plants use non-photochemical quenching (NPQ) to protect themselves from light-induced damage by dissipating excess energy as heat, and genetic studies in crops like maize and sorghum have identified key genes regulating NPQ, offering potential for improving photosynthetic efficiency and yield.
Improving iWUE in sorghum involves balancing water conservation and productivity through genetic traits, particularly aquaporin-linked mechanisms, that enhance photosynthesis and hydraulic efficiency under varying water conditions.
Researchers showed that mutating the Lsi1 Si transporter in sorghum increases lignin content in mature plants, suggesting a compensatory response for reduced silica that could be useful in developing bioenergy crops with optimized lignin and lower Si content.
Researchers revealed that lncRNAs, particularly lncRNA 15962 and lncRNA 11558, play critical roles in regulating cell wall metabolism and Cd transporter gene expression, respectively, contributing to Cd stress responses in sweet sorghum.
