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.
Silencing Gene in Sorghum Plants Significantly Impacts Central Metabolism and Stress Response
Researchers “knocked down” or silenced the phosphoenolpyruvate carboxylase SbPPC3 gene in leaves and roots through RNA interference. Salt stress affected stomatal conductance, yield and central metabolism more in Ppc3 mutant plants.
Unique Chromatin Regulators Discovered in Sorghum
In an effort to prove that epigenetics is behind some of sorghum’s specific features, researchers at Three Gorges University in China sought to clarify the function of the chromatin regulators and their interaction network.
Research Provides Support for Using Agricultural Configuration Techniques to Control Melanaphis sorghi
Researchers at Texas A&M University conducted a two year survey (2019-2020) of the abundance of Melanaphis sorghi and sorghum’s natural pest enemies in 42 sorghum fields located in the South Texas Gulf Coast.
The Epigenetics Behind the Adaptive Response of Sorghum to Phosphorus Deficiency
Recent studies have been successful in elucidating the genetic contributions underpinning the tolerance of some sorghum lines for low phosphorus conditions. Gladman and colleagues studied the environmental influence on how those genes work, known as epigenetics, under limiting phosphorus.
Researchers in Ethiopia Map QTLs for Stem Sugar and Stem Diameter in Sorghum
Scientists identify QTLs for average sugar content (oBrix) and stem diameter under both favorable rainy environmental conditions and unfavorable dry off-season conditions.
