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.
Current technology allows for the identification of the transcriptome expression profile in the plant cells and the use of liquid chromatography/mass spectrometry (LC/MS) technology to investigate the sorghum plant’s metabolites and proteins, providing more information to connect the plant’s genotype and phenotype.
Leaf senescence is the final stage of leaf development. During leaf senescence, nutrients accumulated in mature leaves are broken down and transported to reproductive organs or actively growing young tissues. This process causes reduced photosynthesis, which impacts yield to most
