Fig. 1. Normal morphology and intact cell identities of the mature embryo sac in a SET2030 ovule. (A) Mature embryo sac with four cell types: two synergids, one egg cell and one central cell. (B-F) GUS expression of marker lines for specific cell types of glc embryo sacs in mature ovules. Central cell marker lines are FIS2::GUS (B) and MEA::GUS (C), egg cell marker lines are ET1086 (D) and ET1119 (E), and the synergid cell marker line is ET2634 (F). ccn, central cell nucleus; ecn, egg cell nucleus; scn, synergid cell nuclei. Scale bars: 50 µm.
