A sorghum MYB transcription factor was studied under salt stress conditions. Overexpression reduces biomass accumulation and salinity tolerance, while loss of function leads to longer roots and increased salt tolerance.
Using genetic mapping and sequence comparisons, Mewa et al. identified a single ANTHRACNOSE RESISTANCE GENE 2 (ARG2) in SC328C, which encodes a nucleotide-binding leucine-rich repeat (NLR) protein that produces resistance to certain Cs strains.
The Ethopian sorghum crop is extremely genetically diverse and exhibits a large phenotypic variation. The fact that the germplasm is also widely adapted to both biotic and abiotic stresses makes it a valuable resource for enhancing desirable traits.
Researchers investigated 75 lines of sweet sorghum for phenotypic and genetic variability and found significant differences, which present opportunities for heterotic cross-breeding.
Scientists identified 18 sorghum JAZ genes that have critical functions in the JA signaling pathway and analyzed their promoter regions to identify stress-related cis-acting regulatory elements and transcription factors.
Wu et al. investigated the underlying genetic mechanism behind low HCN content in sorghum and screened 11 simple sequence repeats (SSR) polymorphic primers and, using bulked segregant analysis (BSA), developed four SSR markers associated with low HCN content.
