Summary of Changes to PO October 2011

general

Added new term flower fascicle (PO:0025323)

Made embryo apical cell (PO:0025284) is_a sporophyte m.a.c., rather than is_a m.a.c., to fix redundancy.

Added OBSOLETE as prefix to the definitions of all recently obsoleted terms.

Merging terms to get rid of Zea/Poaceae terms

Existing PO structure for Poaceae anther is below. All of these terms had to be merged, in order to merge zea anther into anther.

made the following merges:

First, got rid of part_of relations. After merging, changed Zea and Poaceae terms to narrow (rather than exact) synonyms. Also, merging gets rid of the "Type: Spanish synonym" tag. Got rid of the extra Spanish synonyms.
