Improved detection of point mutations in an EMS-mutagenized sorghum population by subtracting false negative variants.

Gene Expression affecting dhurrin production in domesticated Sorghum bicolor versus Australian wild Sorghum macrospermum

• SorghumBase Team
• 24 February 2022

Ananda et al. identified genes key to dhurrin synthesis that were highly expressed in S. bicolor, opening up the opportunity to introgress traits from S. macrospermum into domesticated species to create acyanogenic, livestock safe sorghum lines.

Diversity in the Sorghum Pan-Genome Could Contribute to Crop Improvement

• SorghumBase Team
• 18 February 2022

Tao et al, assembled 13 wild and domesticated sorghum genomes, performed a pan-genome analysis of 44,079 gene families, and identified widespread presence/absence variation within 64% of gene families.

Comparative Analysis of Deleterious Mutations in Sorghum versus Maize

• SorghumBase Team
• 10 February 2022

Lozano et al. performed whole-genome resequencing to analyze approximately 13 million variants from 499 sorghum lines, compared the genetic variants with 25 million variants previously identified among 1,218 maize lines, and found that while maize analysis results were in line with the domestication-cost hypothesis, sorghum’s were not.
