EMBRYONIC FACTOR 19 encodes a pentatricopeptide repeat protein that is essential for the initiation of zygotic embryogenesis in Arabidopsis.

Abstract

Early embryogenesis is the most fundamental developmental process in biology. Screening of ethyl methanesulfonate (EMS)-mutagenized populations of Arabidopsis thaliana led to the identification of a zygote-lethal mutant embryonic factor 19 (fac19) in which embryo development was arrested at the elongated zygote to octant stage. The number of endosperm… (More)
