Fig. 1. pCLV3:GFP-ER expression is altered in zll-1 embryos. (A-C) pCLV3:GFP-ER expression (green) in wild-type (WT) Arabidopsis embryos. (A) Transition stage embryo (B) Close-up of stem cells in a torpedo stage embryo. (C) Bent cotyledon stage embryo. (D-F) pCLV3:GFP-ER expression in zll-1. (D) Transition stage embryo. (E) Close-up of stem cells at torpedo stage showing slightly weaker expression than in wild type. (F) Bent cotyledon stage embryo showing no pCLV3:GFP-ER expression. cp, cotyledon primordium; c, cotyledon; sc, stem cells; L1, L2 and L3, tissue layers 1, 2 and 3, respectively; sam, shoot apical meristem; h, hypocotyl. Scale bars: 10 µm in A,B,D,E; 20 µm in C,F.
