New Release: April 2012

The latest release of the Plant Ontology, version #17, is available on our Plant Ontology Browser.

This full release features the addition of almost 140 new terms, for both the 'Plant Anatomical Entity and Plant Structure Development Stage aspects. It also includes new annotation data for Gossypium hirsutum, Picea spp. and updated annotations for many other species.

This release also includes a new feature: The Plant Anatomy Glossary.

The release marks a major revision to the plant structure development stage branch of the PO, including a new root term (plant structure development stage) and many new and revised terms for the whole plant development stage branch. Other new plant structure development stage terms include seed trichome development stage and its subtypes, needed for Gossypium annotations, and secondary xylem development stage and its subtypes, needed to describe wood development.

Revisions to the plant anatomical entity branch of the PO include 29 new terms for vascular tissues or cells, and updated definitions for nearly all vascular and wood-related tissues and cell types.

At the request of several of our user groups, many new subtypes of plant anatomical space, portion of plant substance, and meristem, were also added.
