microgametophyte

[walter mozgala]

Ross,

I think caling the polen grain wall the wall of the microspore is
leaving out much post microspore development.  The microspore wall is
present after meiosis and cytokinesis.  I would assign pollen grain wall
development, including protein injection, etc., to nicrogametophyte
development.  So the pollen wall is new, and formed post meiosis.

again, my two coconuts worth
