Assembly and Annotation of CP-NAM Parental Genotypes to Support Bioenergy Sorghum Research

Scientists have generated de novo genome assemblies for 10 parental genotypes of sorghum (Sorghum bicolor), and identified more than 24,000 large structural variants and over 10.5 million SNPs.

Genetic Determinants of Variability in Yield in Sorghum Lines When Exposed to Low severity Nitrogen Deficit Stress

Grzybowski et al. employed a global, genetically diverse sorghum association panel to explore the variability in metabolic, physiological, and morphological responses to nitrogen deficits and the effect on yield.

Stable Protein, Starch and Amylose QTLs Identified for SC35 × RTx430 Sorghum Population

Researchers from Kansas State University and the USDA-ARS located seven protein, ten starch and ten amylose content in grain sorghum QTLs.

Lectin Influences on Abiotic Stress Resistance in Grain and Sweet Sorghum

When comparing grain to sweet sorghum lines, Osman et al. identified differences in the lectin homologs in the presence/absence of certain other joint domains.They also identified significant overrepresentation of lectins in certain QTLs related to cold and drought tolerance.

Identification of Loci in Sorghum Bicolor That are Associated with Bioactive Molecules Related to Gut Health

Yang et al. evaluated 294 sorghum recombinant inbred lines for their interaction with the human gut microbiome in 12 healthy donors.

Leaf Width and Whole-Plant Transpiration Efficiency in Sorghum

In a large breeding program (701 sorghum lines), leaf width was correlated with plant-level transpiration efficiency and associated with 19 QTL, suggesting it could be a surrogate for transpiration efficiency.

Exploration into Genes Associated with the Stay-Green Trait in Sorghum

Borrell et al. conducted research to explore how genetically modifying PIN genes in sorghum can affect mechanisms underpinning the stay-green drought adaptation phenotype.

Analysis of the ACP Gene Family in Sorghum Supports a Connection with Stress Tolerance

Ge et al. performed phylogenetic analysis of the sorghum ACP gene family and investigated the ACPs expression patterns under abiotic stresses.

Analysis of Serendipitously Observed Red Leaf Phenotype in Sorghum

Lv et al. fine mapped the red leaf gene and identified the metabolites that cause red leaf in sorghum providing a better understanding of the red leaf phenotype in natural sorghum populations.
