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.

Glutinous and Japonica Sorghum Analyzed for Gene Expression and Gene Regulatory Pathways Related to Starch Synthesis

Ke et al. studied two varieties of sorghum, Liaonian3 (glutinous) and Liaoza10 (japonica) and identified genes associated with starch accumulation.

SbWRKY55’s Role in the Abscisic Acid (ABA) Signaling Pathway Regulates Sorghum’s Response to Salt Stress

Song et al. examined the endogenic responses underlying mechanisms for WRKY55 regulation under salt stress tolerance.

Research Provides a Deeper Understanding of Salicylic Acid-Induced Anthracnose Resistance

Researchers from Shandong University in China studied the effect of exogenous SA on resistance in SA sensitive and tolerant sorghum lines. Transcriptome analysis revealed that exposure to SA increases anthracnose resistance through the upregulation of the expression of immune-related genes and pathways.

Link Found Between GRF genes in Sorghum and Aphid Resistance

Shi et al. studied eight GRF genes in the sorghum genome, identifying orthologs through phylogenetic analysis, and evaluating their structural functions and expression patterns under both normal and stressed conditions.

QTLs Identified for Sorghum Resistance to Illinois C. sublineola Pathotype

Khanal et al. identified 47 markers associated with resistance to C. sublineola across all sorghum chromosomes except chromosome 8. Of these, 32 genes were selected as likely causal candidates due to their location near significant SNPs.
