prothallial cell #519

Open planteome-user opened 11 years ago

planteome-user commented 11 years ago

On the POC POC call (12-11-12), we identified that we needed to add this as part of the gymnosperm pollen.

prothallial cell (PO:0025533): proposed def'n: A vegetative plant cell (PO:0009002) that develops from the division of the microspore (PO:0020048) and is part of the microgametophyte of vascular plants other than angiosperms.

prothallial cell (new term): A plant cell (PO:ID) that is part of a prothallium (need to add)

rename existing term: child of prothallial cell microspore prothallial cell (PO:0025533): A plant cell (PO:0009002) that develops from a division of the microspore (PO:0020048) and is part of the microgametophyte (PO:0025280).

Comment: Commonly used in gymnosperms, is vegetative, does not develop into a sperm cell.

prothallial cell (PO:0025533): current def'n: A vegetative plant cell (PO:0009002) that develops from the division of the microspore (PO:0020048) and is part of the microgametophyte of vascular plants other than angiosperms.

Revised: A native plant cell (PO:0025606) which is vegetative and develops from the division of the microspore (PO:0020048) of vascular plants other than angiosperms.

Revised comment: The prothallial cell (PO:0025533) is part of the microgametophyte (PO:0025280) and is believed to be the remnant of the vegetative tissue of the male gametophyte.
