Cartoons and confocal images (A'–C') of the bipolar domains marked byBRXL2p:BRXL2-YFP(yellow) andTMMp:OPL2-BFP(cyan) plasma membranes are in magenta. In meristemoids, BRXL2 and OPL2 localize at opposing PM domains (A) pre-asymmetric cell division (ACD) and are (B) segregated to distinct daughter cells post-ACD. (C) In symmetrically dividing GMCs, they localize to ventral (inner) (OPL2) and outer (BRXL2) domains. Scale bars represent 10 m.
