Composition of Starch Polymers in Waxy, Sweet, and Hybrid Sorghum

Kang et. al., study the relationship between fine structure and the physicochemical properties of starch in sweet and waxy inbreds and hybrid sorghum

ANTHRACNOSE RESISTANCE GENE 2 Imparts Fungal Resistance Without Negatively Affecting Plant Growth

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.

Major traits in Sorghum Bicolor Linked to SNP Markers showing Potential for Future Use in Genomically Selective Breeding

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.
