Multi-locus GWAS of Ethiopian sorghum landraces revealed extensive genetic variation and key candidate genes underlying root architectural traits, providing valuable targets for breeding drought-resilient, water-efficient sorghum cultivars.
Mutations in the sorghum Waxy (GBSS) gene reduce amylose content and create value-added grain traits, and new genomic resources now enable more efficient breeding of waxy sorghum for food, feed, and biofuel applications.
SbWRKY51, a group II WRKY transcription factor in sorghum, enhances salt tolerance by maintaining ion and ROS homeostasis and promoting lignin biosynthesis to strengthen cell wall integrity under salt stress.
Hsu et al., identified distinct rhizosphere nitrogen cycling strategies across diverse Andropogoneae grasses, revealing genetic and ecological mechanisms that could inform more sustainable nitrogen use in cereal crops.
Researchers identified a novel sorghum aphid resistance QTL (qMsa-6) overlapping RMES1 and highlights SbiRTX2783.06G018400 as a key candidate gene, providing molecular targets for breeding durable, aphid-resistant sorghum.
Partial fertility in sorghum cytoplasmic male sterile lines is a complex, environmentally sensitive quantitative trait controlled by many minor-effect loci, which constrains genetic diversity in female parent lines and poses a major challenge for hybrid breeding.
