Summary and Announcements

The latest release of the Plant Ontology, version #20, is available on our Plant Ontology Browser.

This full release features the addition of 48 new terms, for both the Plant Anatomical Entity (44) and Plant Structure Development Stage (4) branches. It also includes new and updated annotation data for Oryza sativa, Gossypium hirsutum and Arabidopsis thaliana.

-Includes all revisions of the Plant Ontology from Revision #1761 to 2199- available on the SVN Site

-For more information, please see also: Details_of_Changes_to_Release_20

The release features revision to the following sections:

Major Revisions to the plant anatomical entity branch:

  • New terms were added to describe the parts of the perianth (PO:0009058), specifically to describe the different forms of a fused perianth (PO:0025880), such as that found in Musa flowers.
  • Thirteen new terms were added to describe the different types of protoxylem (PO:0000272) tissue in the roots and shoots of vascular plants.
  • A term was created for plant sap (PO:0025538) and six sub-classes were added to specify from which part of the plant the sap was collected.
  • We revised the existing tapetum cell (PO:0025543) (was 'tapetal cell') and added three child terms to specify the different types. In collaboration with the Gene Ontology, the corresponding GO biological process terms (anther wall tapetum cell differentiation; GO:0048657 and anther wall tapetum cell fate specification; GO:0010234) were also revised to match.
  • Inflorescence branch (PO:0009081) and its child terms were extensively revised. The existing term paraclade (PO:0004720) was merged into primary inflorescence branch (PO:0006321) and three new child terms were created the describe different types of paraclades: accessory paraclade (PO:0025546); cauline paraclade (PO:0025547); rosette paraclade (PO:0025548).
    • All the children of inflorescence branch (PO:0009081) designating the different branching orders (primary, secondary etc) were renamed from xxx inflorescence axis to xxx inflorescence branch.
  • All the children of infructescence branch (PO:0025243) designating the different branching orders (primary, secondary etc) were renamed from xxx infructescence axis to xxx infructescence branch.
  • trichome PO:0000282 terms:
    • Two new direct children of plant structure (PO:0009011) were added to describe the apical regions of different types of trichome (PO:0000282): trichome apex (new PO:0025550) and trichome tip (new PO:0025549). These have this unusual parentage since they can be part of a multicellular trichome (PO:0000282) (making them a 'portion of plant tissue (PO:0009007)', or part of a unicellular trichome (new PO:0025537), in which case they are a GO cellular component: unicellular trichome apex (GO:0090552) or unicellular trichome tip (GO:0090553).

We also added the subclasses: multicellular trichome apex (new PO:0025551) and multicellular trichome tip (PO:0025535) and a new term was added to describe a unicellular trichome (new PO:0025537).

Revisions to the plant structure development stage branch

Major revision of the branch of flower development stage (PO:0007615):

New terms:

  • collective phyllome structure development stage (PO:0025578): A collective plant organ structure development stage (PO:0025338) that has as primary participant collective phyllome structure (PO:0025023).
  • phyllome development stage (PO:0025579): A plant organ development stage (PO:0025339) that has a primary participant a phyllome (PO:0025023).
  • flower meristem transition stage (PO:0025588): A flower development stage (PO:0007615) which begins with the transition from a portion of meristem tissue (PO:0009013) to a flower meristem (PO:0000229) and ends with the onset of the floral organ formation stage (PO:0025585).
  • floral organ formation stage (PO:0025585): A flower development stage (PO:0007615) which begins with the floral organ meristem development stage (PO:0007601) and ends with the onset of the flowering stage (PO:0025586).


Renamed terms: floral organ meristem development stage (PO:0007601); was: 1 flower meristem visible stage

  • floral organ primordium development stage (PO:0007602); was: 2 flower meristem notched stage
  • floral organ differentiation stage (PO:0007600); was: 3 floral organ development stage
  • flowering stage (PO:0007616); was: anthesis stage; was: 4 anthesis stage and also encompasses 5 post anthesis stage (PO:0007617)- merged into it


post-anthesis (PO:0007617) was merged into flowering stage (PO:0007616; was anthesis stage)

New relation added to order the stages
