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.
Liu et al. systematically identified and characterized 53 DIR genes in Sorghum bicolor, revealing their evolutionary diversification, tissue-specific expression, and key roles in lignin biosynthesis and abiotic stress tolerance, with SbDIR39 and SbDIR53 highlighted as promising targets for crop improvement.
Scientists identified a novel grain size QTL (qGS1) in sorghum and proposed Sobic.001G230700 as a candidate gene using integrated BSA-Seq and RNA-Seq analyses, advancing the genetic understanding of yield-related traits.
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.
