Evidence Found Supporting Stay-Green Alleles Involvement in Drought Adaptation in Sorghum

Researchers studied 590 West African sorghum lines under different types of drought stress conditions and identified drought-tolerant loci.

Genetic Factors Behind Sorghum Leaf Angle Show Promise for Increasing Yield

RNA seq was performed on sorghum collar tissue from different canopy levels. Differentially expressed genes (DEGs) were filtered and 11 candidate genes that can be leveraged to improve leaf angle.

Quicker, More Cost Effective Method for Assessing the Phenotypic Characteristics Associated with Stalk Lodging

Using a stereoscope and a semi-automated image processing algorithm, the researchers are able to produce finite element models of plant stalks in under a day with a relatively low equipment cost

Performance Prediction Through Genomic Selection in Hybrid Sorghum

Researchers study the utility of genomic selection for predicting the performance of hybrid grain sorghum, and identify an effective method that models the interaction between genotypes and the environment to optimize crop outcomes.

Inadvertent Introgression: Pleiotropy and the Sorghum Genome

Mural et al. analyzed existing trait datasets and found evidence for the presence of previously unknown pleiotropic genes in the sorghum genome.

QTL Identified for Source-Sink Relationships in a Bi-Parental Recombinant Inbred Line Population

Sorghum grown under favorable conditions has high production potential. Photoassimilate production at the source (leaf) and transport to the sink (grain) are primary determinants of the yield. Mapping Quantitative Trait Loci (QTL) for source-sink relationships is of interest to biologists

An improved high-resolution method for the in silico detection of EMS-induced mutations in sorghum mutant populations

Improved detection of point mutations in an EMS-mutagenized sorghum population by subtracting false negative variants.

Gene Expression affecting dhurrin production in domesticated Sorghum bicolor versus Australian wild Sorghum macrospermum

Ananda et al. identified genes key to dhurrin synthesis that were highly expressed in S. bicolor, opening up the opportunity to introgress traits from S. macrospermum into domesticated species to create acyanogenic, livestock safe sorghum lines.

Diversity in the Sorghum Pan-Genome Could Contribute to Crop Improvement

Tao et al, assembled 13 wild and domesticated sorghum genomes, performed a pan-genome analysis of 44,079 gene families, and identified widespread presence/absence variation within 64% of gene families.
