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.
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.
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.
‘Sodamchal’, a line of Korean sorghum known for its salt sensitivity, was subjected to salt-stress. Physiological and transcriptomic changes were investigated to identify good candidates for stress indicators and candidate genes for the salt stress group.
