New and Obsolete Terms

See separate page for a list of New terms and obsolete terms for February 2012 release.

Term changes

Made whole plant growth stage (PO:0007033) is_a plant structure development stage, changed definition and renamed whole plant development stage

Merged plant structure development stage (PO:0007021) into plant growth and development stage (PO:0009012) and made plant structure development stage the primary name and changed definition. Still need to fix comment based on BS's comment.

Made gametophyte development stage and sporophyte development stage part_of life of whole plant (PO:0025337).

Made flower, fruit and inflorescence development stage is_a collective plant structure development stage (PO:0025338)

Made leaf development stage and root development stage is_a plant organ development stage.

Made the following terms subtypes of sporophyte development stage:

sporophyte vegetative stage (PO:0007134)

sporophyte reproductive stage (PO:0007130)

sporophyte senscent stage (PO:0007017)

sporophyte dormant stage (PO:0007132)


Made protonema whole plant development stage (PO:0030006) is_a gametophyte vegetative development stage, redefined and removed part_of relation to gametophyte phase.

Wrote new definitions for gametophyte and sporophyte dormant stage. Need to put on SF.

Changed name of awn (PO:0006032) to lemma awn. Modified text definition to reflect that it is part of awn. Existing annotations should stay with PO:0006032.

Added leaf venation as a related synonym of leaf vascular system (PO:0000036)

Added tendril as broad synonym of all tendril types: leaf tendril (PO:0025361), leaflet tendril (PO:0025362), leaf apex tendril (PO:0025363), branch tendril (PO:0025364), stem apex tendril (PO:0025365), leaf rachis tendril (PO:0025366), prophyll tendril (PO:0025367)

Added diaspore as broad synonym to seed (PO:0009010), fruit (PO:0009001), spore (PO:0025017), corm (PO:0025355), bulb (PO:0025356), tuber (PO:0004543)

updated the names and definitions of gametophyte/sporophyte development stage and their direct descendents to match what is on SF tracker.

Renamed PO:0007631 from embryo development stages to embryo stage, and made is_a sporophyte vegetative stage. New definition.

Renamed PO:0001097 from A zygotic stage to zygote stage, and made is_a sporophyte development stage. New definition.

Changed definition of of plant embryo (PO:0009009) to say that it participates in the embryo stage. Changed wording in comment to say "embryo stage" instead of "embryonic phase".


Relation changes

Added new relation has_participant. Domain = plant structure development stage, Range = plant anatomical entity.

The participates_in relation was added during the last release. For improved reasoning, the domain and range were specified. Domain = plant anatomical entity, Range = plant structure development stage.

Changed name of derives_from to derives_by_manipulation_from and added definition and comment.
