Abstract: Disclosed are methods of obtaining clonal seeds, methods of plant cloning, methods of screening for maternal plants that produce clonal seeds asexually and methods of increasing yield of clonal seeds. Also disclosed are constructs comprising a nucleic acid that may silence the activity of a RNA-dependent DNA methylation pathway gene. Further disclosed are maternal plants comprising a construct wherein the construct comprises an exogenous nucleic acid sequence, wherein the construct renders the maternal plant defective for RNA-dependent DNA methylation.

Abstract: This invention relates to the isolation and characterization of a Polycomb gene from Arabidopsis with maternal control of embryogenesis. The novel gene and gene product may be used to manipulate embryo and endosperm cell proliferation for the generation of parthenocarpy, seed specific characteristics, inhibition of propagation of undesirable plants or apomixis in Arabidopsis and other plant types. Two mutations of this gene have also been identified which identify maternal effect embryo lethality.
