The angiosperm ovule is characterized by the close association of the two generations, with the haploid female gametophyte or embryo sac being encapsulated by the diploid sporophyte, which usually forms two integuments. How the gametophyte and sporophyte coordinate their development has long been of interest. However, the function of the inner integument in embryo sac development has remained elusive. Here, we addressed this question. We applied a genetic ablation strategy to achieve an early block in inner integument outgrowth. We generated plants expressingBARNASEunder the control of an early acting endothelium-specific promoter. Corresponding lines carried ovules lacking most of the inner integument. The genetic and cell biological data revealed that in the near absence of an inner integument embryo sac development is blocked at the mono-nuclear embryo sac stage in most pre-fertilization ovules. Approximately 10 percent of the ovules developed a functional embryo sac and underwent fertilization. Subsequent embryo and endosperm development appeared unperturbed and viable seeds were produced albeit of altered shape. Our results show that the inner integument plays an important role in early embryo sac development as well as ovule and seed shape, but is dispensable for embryo and endosperm development. Key words: embryo sac, embryo, endothelium, female gametophyte, integument, seed developmentHighlightGenetic ablation of the inner integument demonstrates its role in embryo sac development and its irrelevance for embryogenesis.
