About Sorghum bicolor

Sorghum bicolor

Sorghum bicolor is a widely grown cereal crop, particularly in Africa, and Sorghum ranks 5th in global cereal production. The genome is approx. 730 Mbase and has a haploid chromosome number of 10. Although highly repetitive, the genome is more tractable for sequencing than its close relative, Maize. [more]

Genome Sequencing and Gene Prediction (release Sbi1.4)

The genome assembly of Sorghum bicolor cultivar Moench was published in 2009 [1]. Sequencing by the US department of Energy Joint Genome Institute (JGI) Community Sequencing Program in collaboration with the Plant Genome Mapping Laboratory followed a whole genome shotgun strategy reaching 8x coverage with scaffolds, where possible, being assigned to the genetic map. Gene predictions resulted from combining homology-based and ab initio methods with expressed sequences from sorghum, maize and sugar cane, using the JGI annotation pipeline. This browser presents data from the Sbi1 assembly and Sbi1.4 gene set (March 2007). [more].

Gramene/Ensembl Genomes Annotation

Additional annotations generated by the Gramene/Ensembl Genomes projects include:

  • The standard set of Gramene analyses detailed here.
  • Phylogenetic gene trees and whole-genome alignments with several plant and metazoan species, using Ensembl's Compara pipeline.

This release of the assembly (Sbi1) for Sorghum bicolor is composed of 10434 chunks with a total length of 738.5 Mb assembled into:

  • 10 chromosomes with a total length of 659.2 Mb
  • 3294 scaffolds with a total length of 79.3 Mb
