Expression pattern of LEC1 in Arabidopsis and B. napus. A-C, GUS analysis of BnLEC1 promoter in Arabidopsis. (A) globular-shape embryo stage; (B) heart-shape embryo stage; (C) cotyledon stage. Insets in (A) and (C) are whole seed pictures. ep, embryo proper; es, embryo suspensor; em, embryo; en, endosperm; ch, chalazal zone. Bars = 20 μm. (D) Expression levels of BnLEC1 in endosperm and cotyledon tissues at the cotyledon stage of B. napus.
