Female gametophytic mutants: diagnosis and characterization.

Abstract excerpt

In plants, gametes are formed in multicellular haploid structures, termed gametophytes. The female gametophyte of most higher plants comprises seven cells, which develop from a single haploid spore through nuclear proliferation and subsequent cellularization. The female gametophytic cells differentiate into four distinct cell types, which play specific roles during fertilization and seed formation thereby...
