G14 emerged as the most stable and high-yielding red sorghum genotype with superior nutritional traits, making it ideal for cultivation across diverse environments in Tamil Nadu.
Rp2: A Novel Rust Resistance Locus from Sudanese Sorghum for Broadening Genetic Diversity in U.S. Breeding Programs
By unlocking rare, evolutionarily conserved rust resistance locus from the Sudanese sorghum core collection, this work bridges global germplasm diversity with modern breeding, revealing Rp2 locus is a tractable genomic entry point for stacking durable, multi-disease resistance and strengthening the genetic resilience of U.S. sorghum improvement.
Genetic Architecture and Co-Localized QTL Underlying Plant Height and Brix Content in Sorghum
Genetic modeling and high-density QTL mapping reveal that sorghum plant height and brix content are governed by interacting major genes and polygenes, share co-localized loci that explain their phenotypic correlation, and are influenced by auxin- and carbon-fixation–related candidate genes that offer targets for breeding improved varieties.
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.
High-Throughput, Nondestructive Grain Quality Analysis in Sorghum
Understanding sorghum grain quality is essential for breeding, food innovation, and industrial applications. Traits such as protein, starch composition, oil content, tannins, and phenolic compounds directly influence nutritional value, processing behavior, and end use. However, traditional laboratory assays are slow,
CSI Seminar Brent Crafton, Lanier Dabruzzi, Shelee Padgett and Zach Simon Jan 13 at 11 AM CT
The Center for Sorghum Improvement (CSI) will host a virtual seminar given by Brent Crafton, Lanier Dabruzzi, Shelee Padgett and Zach Simon, members of the Sorghum Checkoff Marketing Team, on Tuesday, January 13 at 11:00 AM CT. Their talk, “Moving
Hormonal Regulation of Sugar Transport Drives Salt Tolerance Through Strategic Resource Allocation in Sorghum
Salt tolerance in sorghum is closely linked to hormone-regulated sugar transporter expression that controls resource allocation between roots, stems, and grains during development, enabling stress-resilient genotypes like Della to delay sodium translocation and sustain metabolic balance.
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.
Gramene and SorghumBase Teams at PAG33 in San Diego, California, January 9-14, 2024
The International Plant and Animal Genome conference (PAG33) will take place on January 9-14, 2026 in San Diego, California and the SorghumBase and Gramene teams will be there!
Integrated Physiological and Molecular Mechanisms Underlying Sorghum Responses to Alkali Stress
Liu et al. found that though alkali stress disrupts growth, osmotic balance, and cellular stability in sorghum, the tolerant genotype Z14 counters these effects through stronger antioxidant defenses, enhanced osmotic regulation and rapid activation of stress-responsive genes and signaling pathways.
