Putative gene split models available

Putative gene split models are available for 18 plant reference genomes hosted at Gramene. The split gene models are commonly related to an annotation artifact wherein a single gene is annotated as two or more genes due to incomplete evidence, but could also result from legitimate evolutionary processes. The Compara Gene Tree method predicts a special class of within-species paralogs called "contiguous_gene_split". A contiguous_gene_split is called when the two apparently paralogous genes lie on the same strand and in close proximity (<1MB) but have no (or little) overlapping sequence. The putative gene split models for all 18 species together and separately for each species can be downloaded from the Gramene ftp site.
