Arabidopsis thaliana (thale cress) genome

The TAIR8 release contains 27,235 protein coding genes, 4759 pseudogenes or transposable elements and 1288 ncRNAs (33,282 genes in all, 38,963 gene models). A total of 1291 new genes and 2009 new gene models were added. Thirteen percent (4330) of Arabidopsis genes now have annotated splice variants. Updates were made to 3811 gene structures of which 625 gene models had CDS updates; a total of 4007 exons were modified and 683 new exons incorporated. There were 33 gene splits and 41 gene merges. Overall 23% of all existing TAIR7 genes (7380 genes) were updated (includes split, merged and deleted genes as well as locus type changes, structural updates and sequence updates) for TAIR8. Changes to chromosome sequences include removal of vector/Ecoli contamination and 1425 single nucleotide substitutions. Additional details can be viewed at the TAIR websit
