New synonyms

This is only to highlight synonyms that are substantially different than the primary term name (e.g., cone as a synonym of strobilus) or are otherwise noteworthy.

Added 333 new synonyms from FNA term glossary to existing PO terms.

Added synonyms: lateral meristem - lateral growth meristem; shoot lateral meristem - shoot lateral growth meristem; root lateral meristem - root lateral growth meristem

Added broad synonyms to 34 terms that had plant in the name, so they would show up in searches for an exact match (e.g., "embryo" as synonym of "plant embryo", "organ" as synonym of "plant organ").

Added "leaf venation" as related synonym of leaf vascular system (PO:0000036)

Added diaspore as broad synonym to seed (PO:0009010), fruit (PO:0009001), plant spore (PO:0025017), corm (PO:0025355), bulb (PO:0025356), and tuber (PO:0004543).

Added "leaf margin blastozon" as exact synonym to leaf marginal meristem.

Added "midrib" and "mid rib" as broad synonyms to both costa (PO:0030072) and midvein (PO:0020139)

Added colony (related), clonal colony (related), genet (broad), ramet (broad) as synonyms of whole plant (PO:0000003).

Added "ramet" as broad synonym of gametophore (PO:0030018).

Added "simple strobilus", "compound strobilus", and "strobili" as synonyms of strobilus (PO:0025083).

Added "SAM" as synonym of shoot apical meristem (PO:0020148).

Got rid of old GRO synonyms on sporophyte dormant stage These synonyms were not relevant to the term, and the GRO ontology is no longer in use.

Merged terms

plant structure development stage (PO:0007021) into plant growth and development stage (PO:0009012) -- plant structure development stage is primary name

Obsolete terms
