Info • Sorghum bicolor
v1.0 (March 26, 2008): This Sorghum bicolor assembly was built using the Arachne assembler with a data freeze from January 25, 2007. After the build, 28 breaks and 108 manual joins were made. 10 of these joins were across centromeres, and the size of the centromere was estimated for each chromosome based upon the amount of centromeric sequence already assembled for that chromosome. The main genome is in 10 chromosomes with many small unmapped pieces, some of which contain homologous rice genes. The Sorghum bicolor mitochondria and chloroplast were previously sequenced and are available in Genbank at NC_008360 and NC_008602. The nuclear genome sequence from the assembly was annotated using the JGI Genome Annotation Pipeline, collaborator-contributed gene models, and custom analyses.
