Gene ontology functional annotation datasets for the ITAG3.2 and ITAG4.0 tomato () genome annotations.

Functional annotation based on Gene Ontology has provided a structured and comprehensive system to access the current knowledge about the function of genes. For model plants such as , there is a constant updating and restructuring of the functional annotation that increases the reliability of the analyses that use it. For tomato (), a crop widely used as a model plant for the study of fleshy fruits, there is no functional annotation, at least not freely accessible, even though its genome has long been sequenced and annotated.
