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.
High Throughput, Low Cost Colorimetric Assay for Assessing Hydrogen Cyanide Potential in Sorghum
Nakasagga et al. developed a colorimetric assay that is fast and inexpensive and can both measure the HCN-P and allow comparison with existing visual assays.
Phenotypic and Genetic Diversity in Sweet Sorghum Presents Opportunities for Strengthening Valued Traits Through Cross-Breeding
Researchers investigated 75 lines of sweet sorghum for phenotypic and genetic variability and found significant differences, which present opportunities for heterotic cross-breeding.
Identification and Promoter Analysis of 18 Sorghum JAZ Genes with Critical Functions in the JA Signaling Pathway
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.
Genetic Mapping Behind Low Hydrocyanic Acid in a Sorghum-Sudangrass Hybrid
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.
The Effect of Phytohormones on the Response of Sorghum Lines to Sugarcane Aphid Infestation
Huang et al. investigated the role of phytohormones in host plant resistance to aphid attack and found that phytohormones play a positive role in plant defense against aphids.
Researchers Discover Potential Starch Biosythesis Regulator in Sorghum
Using gene expressions and co-expression analysis, the researchers found a regulatory factor, the gene SbDof21, which was found to be a highly expressed DOF gene in grains, on chromosome 5 in sorghum.
Transcriptomic and Metabolic Analyses Give Further Insight into the Response of Two Sorghum Lines to Salt Stress
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.
Connection Between SbWRKY50 in Sorghum and Suppression of Chlorophyll Degradation and Leaf Senescence
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
Identification of Marker-Trait Associations for Sorghum Aphid Resistance
Researchers used the Sorghum Association Panel (SAP), as well as some additional lines, to pinpoint new genomic regions connected to resistance to the sorghum aphid.
