New or modified relations, PAE

Removed:

• peduncle part_of inflorescence (incorrect relation, does not work for cases of single flowers)

Changed

• 'leaf develops_from vascular leaf primordium' to 'vascular leaf develops_from vascular leaf primordium

• "archegonium egg cell part_of archegonium" to "archegonium egg cell located_in archegonium"

• petiole lamina (PO:0025129) moved to is_a lamina, instead of is_a leaf lamina.
• lamina (PO:0025060) Moved from is_a cardinal organ part to is_a cardinal part of multi-tissue plant structure, (to allow for lamina on seeds and fruits)

• tuber cortex (PO:0025055): moved to is a cortex, rather than a shoot axis cortex.

A portion of cortex (PO:0005708) that is part of a tuber storage parenchyma (PO:0025036).

• tuber pith PO:0025052: Moved to is a pith, rather than a shoot axis pith. Def'n did not need to be changed.

A portion of pith (PO:0006109) that is part of a tuber storage parenchyma (PO:0025036).

• tuber storage parenchyma moved to part_of a tuber (PO:0025522), added comment: 3005637

If you are annotating to this term, please add an additional annotation to either shoot axis tuber (PO:0004543) or tuberous root tuber (PO:0025476).

Added:

• cardinal organ part (is_a cardinal part of MTPS and part_of plant organ); added cross product to definition
• organ margin (PO:0025005) part_of organ lamina
• phyllome margin (PO:0025018) part_of phyllome lamina (latter as XP).
• laticiferous cell (PO:0004005, obsolete) replaced_by laticifer cell (PO:0025031)

Updated definitions and/or comments: PSDS terms

• flower development stage (PO:0007615)

• fruit development stage (PO:0001002)-

• collective plant organ structure development stage (PO:0025338)- modified definition and comment to include PO:ids.

• whole plant fruit formation stage (PO:0007042)

• whole plant fruit ripening stage (PO:0007010)

• whole plant flowering stage (PO:0007016)

New or modified relations, PSDS

• Made fruit development stage is_a plant structure development stage (instead of collective plant organ structure development stage)

Added relation collective plant organ structure development stage has_participant collective plant organ structure, using intersection_of tags.

Made whole plant fruit formation stage (PO:0007042) and whole plant fruit ripening stage (PO:0007010) subclasses of whole plant fruit development stage and updated their definitions.

Updated names and definitions of:

• (PO:0007009) whole plant fruit formation stage 10 to 30%
• (PO:0007029) whole plant fruit formation stage 30 to 50%
• (PO:0007007) whole plant fruit formation stage 50 to 70%
• (PO:0007027) whole plant fruit formation stage 70% to final size
