Summary of Changes to PO July 2012

Updated definition of areole bud (PO:0025353), phyllome lamina areole (PO:0025391), leaf lamina areole (PO:0025392), leaf lamina vein (PO:0020138), axillary vegetative bud (PO:0004712), terminal vegetative bud (PO:0004716)

Added "vascular tissue" exact synonym of "portion of vascular tissue".

Modified definition and comment of tuber (PO:0004543) and comment of subterranean tuber (PO:0004547).

Made 8 terms subtypes the bin term floral structure primordium (PO:0025477).

Made primordium (PO:0025127) is_a meristem, and updated definition.

Updated definitions of subtypes of primordium: androecium primordium, anther primordium, gynoecium primordium, ovule primordium, phyllome primordium, vascular leaf primordium, carpel primordium, cotyldeon primordium, lodicule primordium, petal primordium, sepal primordium, stamen primordium

Added "portion of xxx primordium tissue" as synonyms to all primordium types.

Updated definition of root primodrium and lateral root primordium, and removed relation lateral root primordium develops_from pericycle (PO:0006203), because it is not always true.

Added adventitious root primordium as synonym of basal root primordium and shoot-borne root primordium.

Updated definition of root anlagen. Made it is_a portion of plant tissue

Added tuber branch as exact synonym of tuber.

Added promersitem as synonym of apical meristem and shoot apical meristem (broad). Was synonym of only root apical meristem.

Changed definition of shoot apex to say "has as parts ...the youngest phyllome primordia" instead of "...leaf primordia".

Changed name of auricle (PO:0020106) to leaf sheath auricle and synonym to leaf sheath ear, updated definition, and changed from part_of vascular leaf to part_of leaf sheath.

Changed "pistil", as synonym of gynoecium, from related to exact. Added "pistil primordium" as exact synonym of gynoecium primordium.

Added comment to gynoecium and carpel: In some cases, a gynoecium may consist of only one carpel, in which case annotations should go on carpel (PO:0009030). The word pistil is used synonymously with gynoecium, but if a gynoecium consists of a single carpel, then pistil may be used synonymously with carpel.

Updated definitions and comments of phyllome marginal meristem and leaf marginal meristem.

Added phyllome margin part_of phyllome lamina

Removed phyllome marginal meristem part_of phyllome (now redundant)

Removed phyllome marginal meristem part_of phyllome primordium

Removed leaf marginal meristem part_of vascular leaf primordium

Updated definitions of phyllome primordium to say that it is part of shoot apex, plus definition of cotyledon and vascular leaf primordium to say they are part_of vegetative shoot apex, and definition of bract primordium part of reproductive shoot apex. Relations were already there. Added "is part of a reproductive shoot apex (PO:0025222)" to definition of floral structure primordium and removed redundant relations from its subtypes.

Added "part_of peripheral zone (PO:0000225)" to definition of phyllome anlagen (relation was already there).

Added relations: bract primordium develops_from bract anlagen, lodicule primordium develops_from lodicule anlagen, petal primordium develops_from petal anlagen, sepal primordium develops_from sepal anlagen, stamen primordium develops_from stamen anlagen

Changed name of meristem (PO:0009013) to portion of meristem tissue

Added "AM" as exact synonym of apical meristem.

Updated definition of gynoecium.

Changed pistil to broad synonym of gynoecium and carpel

Added syncarpous gynoecium and apocarpous gynoecium as synonyms of gynoecium.
