Sorghum kernel composition is a crucial characteristic that determines its functional qualities. The total protein content of sorghum grain increases under drought stress, but starch, protein digestibility, and micronutrient contents decrease. Sorghum (Sorghum bicolor L.

- Sorghum anthracnose is a severe disease impacting sorghum yields, with resistant varieties being key for effective management.
- A study evaluated 25 isolates from Ethiopia, revealing significant differences in virulence among them, with certain isolates showing a high degree of pathogenicity.
- Findings identified specific sorghum genotypes with resistance potential, highlighting the importance of genetic diversity in developing resilient cultivars.
Article Synopsis
- Sorghum anthracnose, caused by the fungus Colletotrichum sublineola, significantly affects global sorghum productivity, making the identification and introgression of resistant genotypes imperative for improvement.
- Field experiments on 358 sorghum accessions in Ethiopia uncovered 53 resistant accessions and 213 with varying resistance to local pathogens, leading to a genome-wide association study (GWAS) identifying 38 genetic loci linked to anthracnose resistance.
- Notably, specific SNPs associated with genes related to immune responses were identified, suggesting targeted genes for further breeding efforts to enhance resistance in sorghum cultivars.
Article Synopsis
- The genetic resources of sorghum in Africa, particularly in Ethiopia, are underutilized for developing new cultivars, despite their potential for local adaptation and improved traits.
- A study characterized 560 sorghum accessions, using genotyping by sequencing to identify significant genetic diversity, revealing 10 distinct clusters that align with botanical races and ecological types.
- The findings suggest a strong foundation for hybrid breeding programs by leveraging local germplasm, aiming to enhance productivity and resilience in sorghum cultivars.
Background: Sorghum grain mold is the most important disease of the crop. The disease results from simultaneous infection of the grain by multiple fungal species. Host responses to these fungi and the underlying molecular and cellular processes are poorly understood.
