This study identifies and validates new stable dw3 dwarfing alleles using sorghum pangenome data to improve genetic diversity and eliminate height revertants in U.S. grain sorghum breeding.
The Center for Sorghum Improvement (CSI) will host a virtual seminar by Dr. Daran Rudnick, Professor and Director of Sustainable Irrigation in the Carl and Melinda Helwig Department of Biological and Agricultural Engineering at Kansas State University Research and Extension, on Tuesday, December 8 at 11:00 AM CT. His talk is titled, “Connecting Sorghum Production to Groundwater Outcomes: Perspectives from TAPS.”
This August, I had the honor of representing the AgBioData Single-Cell Biocuration Working Group at the Gordon Research Conference on “Single-Cell Approaches in Plant Biology” in Portland, Maine. Thanks to the AgBioData Ambassador Award, I joined an incredible community of researchers from August 10-15 to explore how we are revolutionizing plant science by zooming in to the cellular level. Single-cell technologies let us see what individual cells are doing, and the insights are transforming everything from basic biology to crop development.
Research reveals that drought stress disrupts photosynthesis by down-regulating key genes in C3 (wheat) and C4 (sorghum) plants, with wheat exhibiting greater susceptibility, highlighting potential genetic targets for improving drought tolerance in crops.
The MGS1 gene in sorghum, encoding a MIKC-type MADS-box transcription factor, regulates the multiple-grain spikelet (MGS) trait, with natural mutations like mgs19E and mgs1BA45 significantly increasing grain yield by producing adjacent double-pistil primordia.
Sorghum, a high-biomass crop, shows promise for phytoremediation of cadmium (Cd)-contaminated soils, with Cd uptake and translocation largely influenced by genotype-specific expression of ABC transporter proteins, particularly SbABCB11.
Sorgoleone enhances arbuscular mycorrhizal fungi (AMF) colonization in sorghum, optimizing phosphorus uptake and plant growth, with 20 µM identified as the optimal concentration for symbiotic efficiency.
The Center for Sorghum Improvement (CSI) will host a virtual seminar by Dr. Vincent Vadez, Crop Physiologist and Agronomist for the French National Research Institute for Sustainable Development (IRD), on Tuesday, November 11 at 9:00 AM CT. His talk is titled, “Transpiration efficiency and response to high sowing density: Two connected opportunities for yield improvement in sorghum.”
The Sequential SNP Prioritization Algorithm (SSPA) refines GWAS results by leveraging correlation-based feature engineering to prioritize SNPs associated with complex traits in sorghum, providing valuable insights for functional genomics research and enabling downstream machine learning applications.
