Fig. 2. Effects of the glo1-1 mutation on early endosperm development.
Developing endosperm in (A,C,E) wild-type and (B,D,F) glo1-1 mutants.
(A) Wild-type syncytium. (B) Abnormal accumulation of nuclei in
glo1-1 basal syncytium (arrow). (C) Wild-type cellularising endosperm
with first cell layer formed. (D) glo1-1 endosperm showing abnormal
cellularisation in the basal region (arrow). Fully cellular (E) wild-type
endosperm and (F) glo1-1 endosperm with constrictions around the
apical region (arrow) and abnormal basal endosperm morphology. en, endosperm;
nu, nucellus; p, pericarp; z, zygote. Scale bars: 50 µm.
