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.
Whole-genome resequencing of recombinant inbred lines (RILs) that were products of crosses between Colletotrichum sublineola (Cs)-resistant lines and Cs susceptible lines identified a locus that confers Cs resistance as well as resistance to other fungi.
Researchers used whole genome resequencing to “harness” the diversity and perenniality inherent in the wild Sorghum halepense line. The better variant distribution pattern in the present study opens up the opportunity for boosting gene and major marker discovery, particularly in the pericentromeric regions, on which there is little information.
Researchers from Ohio University developed PlantNexus, a gene co-expression network (GCN) and visualization interface for sorghum and barley. The gene functions and regulatory mechanisms that GCNs could help study are of fundamental importance in increasing nutrients and yield.
RIO and SN005, two inbred sorghum lines that are representatative of salt-tolerant and intolerant breeds respectively, showed significant differences in transcription factor (TFs) expression and secondary metabolic pathways and hormone signaling pathways in the first two hours after the salt treatment.
Researchers conducted the first genome-wide analysis of MARKK and MAPKK genes in sorghum. The researchers hypothesize that SbMPK14, SbMAPKKK39, and SbMAPKKK47 are critical genes in water stress tolerance in sorghum.
