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.
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.
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.
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.
