This page provides information on the status of the Arabidopsis thaliana genome. Genome statistics are based on the Araport11 release dated June 2016.
Summary of Gene Functional Annotation
The pie charts below summarize the state of functional annotation of the Arabidopsis genome (excluding pseudogenes) based on links to terms in the three GO ontologies (dark green:known, from experimental evidence, light green: known, from other evidence, yellow:not yet curated, red:curated but unknown). The pie charts for GO process, function and component are based on annotation data as of May 24, 2016.
The bar graphs below represent the distribution of Arabidopsis genes among high level Gene Ontology, or GOslim, categories based on their annotations to terms falling within these categories. Bar graphs are based on annotation data as of May 24, 2016.
Summary of Gene Structure Annotation
The Araport11 release contains 27,655 protein-coding genes, 5,051 non-coding genes, 3,901 transposable element genes, 952 pseudogenes, 508 novel transcribed regions, and 111 upstream open reading frames. No changes were made to the genome assembly. For more detailed information about the Araport11 release, please see the Araport11 manuscript on BiorXiv.
