Updated Putative Split Gene Models Available

Putative gene split models are available now for 23 plant reference genomes based on the latest Gramene release 36b (Gramene36bEnsembl70) hosted at Gramene. The split gene models are commonly related to an annotation artifact where 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 each species can be downloaded from Gramene ftp site
