Sb bicolor IS12661 Assembly and Gene Annotation
About Sorghum IS 12661
IS 12661 is a landrace of Sorghum bicolor collected at Dire Dawa-Isa-Gurgur (9.579999, 41.860001), Hararghe province, Ethiopia. Other identifiers are SA 2355 and PI 276837. The accession is classified in the caudatum race and considered representative of the zerzera type within that race. IS 12661 and several of its derivatives from the Sorghum Conversion Program (SC170s) have contributed substantially to modern grain sorghum breeding.

Assembly
The genome assembly of Sorghum IS12661 was reported in Tao et al (2021). Sequencing was conducted by the Australia Sorghum breeding team in collaboration with BGI-Shenzhen using Illumina HiSeq 4000 platform and the PacBio Sequel platform to achieve 171X and 36X coverage, respectively. The assembly effort generated a genome of 622.1Mb with contigs N50 of 163.7kb.
Annotation
Gene prediction was performed using a hybrid approach combining de novo gene predictors and evidence-based methods (Tao et al 2021), which led to the identification of 33,979 genes in the genome.
