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.
Genetic Regulation of the Multiple-Grain Spikelet Trait in Sorghum: Insights into MGS1 and Its Role in Enhancing Grain Yield
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.
Genotypic Variation in ABC Transporters Influences Cadmium Phytoremediation Potential of Sorghum
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.
Dissecting the Genetic Basis of Root Traits in Sorghum Using Genome-Wide Association Studies
A genome-wide association study in sorghum identified 189 QTNs underlying root system architecture, highlighting a complex polygenic basis with candidate genes linked to hormone signaling, flavonoid biosynthesis, and stress adaptation.
Subfunctionalization of MBW Complex Components in Sorghum Reveals Loss of Pleiotropy in Tannin1
Tannin1 in sorghum does not act as a pleiotropic master regulator of leaf pigmentation or chilling tolerance, supporting a model of subfunctionalization of MBW components in panicoid grasses.
SbWRKY51 Positively Regulates Sorghum Salt Tolerance Through Coordinated Control of ROS Homeostasis and Lignin Biosynthesis
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.
Optimizing Sorghum–AMF Symbiosis: The Role of Sorgoleone in Enhancing Phosphorus Uptake and Plant Growth
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.
Genomics-Assisted Breeding of Waxy Sorghum: Advances in Molecular Tools for Applications in the Food, Feed, and Biofuel Sciences
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.
CSI Seminar Vincent Vadez, Nov 11 at 9 AM CT
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.”
Sequential SNP Prioritization Algorithm (SSPA): A Correlation-Based Post-GWAS Framework for Trait-Associated SNP Discovery 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.
