Genetic Dissection of Seed Dormancy in Sorghum Reveals qDOR-9 as a Key Locus Linked to ABA Sensitivity, Flowering Time, and Pre-Harvest Sprouting Susceptibility

Rodríguez et al. identified and validated the qDOR-9 locus in sorghum as a key regulator of seed dormancy, linking it to ABA sensitivity and flowering time, and highlighting its unintended association with PHS susceptibility due to historical breeding for dwarfism.

Identification of a BPM Domain-Containing Gene Regulating Panicle Exsertion in Sorghum for Mechanized Harvesting Adaptation

Ao et al. identified a BPM domain-containing gene on chromosome 10 as a key regulator of panicle exsertion in sorghum, linking impaired BR signaling and reduced parenchyma cell elongation to a sheathed panicle phenotype, with implications for breeding varieties suited for mechanized harvesting.
