Journal ArticleDOI
Plant Embryogenesis: Zygote to Seed
TL;DR: Recent genetics studies in Arabidopsis have identified genes that provide new insight into how embryos form during plant development, and these studies, and others using molecular approaches, are beginning to reveal the underlying processes that control plant embryogenesis.
Journal ArticleDOI
Mutations in FIE, a WD Polycomb Group Gene, Allow Endosperm Development without Fertilization
Nir Ohad,Ramin Yadegari,Linda Margossian,Mike Hannon,Daphna Michaeli,John J. Harada,Robert B. Goldberg,Robert L. Fischer +7 more
TL;DR: Cloning of the Arabidopsis FERTILIZATION-INDEPENDENT ENDOSPERM (FIE) gene suggests that the FIE Polycomb protein functions to suppress a critical aspect of early plant reproduction, namely, endosperm development, until fertilization occurs.
Journal ArticleDOI
Female Gametophyte Development
Ramin Yadegari,Gary N. Drews +1 more
TL;DR: Early in their evolution, plants acquired a life cycle that alternates between a multicellular haploid organism, the gametophyte, and a multi-cellular diploid organisms, the sporophyte.
Journal ArticleDOI
Control of fertilization-independent endosperm development by the MEDEA polycomb gene in Arabidopsis
Tomohiro Kiyosue,Nir Ohad,Ramin Yadegari,Mike Hannon,José R. Dinneny,Derek Wells,Anat Katz,Linda Margossian,John J. Harada,Robert B. Goldberg,Robert L. Fischer,Robert L. Fischer +11 more
TL;DR: Grossniklaus et al. as mentioned in this paper used a map-based strategy to identify a mutation in Arabidopsis, f644, that allows for replication of the central cell and subsequent endosperm development without fertilization.
Journal ArticleDOI
Imprinting of the MEDEA Polycomb Gene in the Arabidopsis Endosperm
TL;DR: Results suggest that the embryo abortion observed in mutant mea seeds is due, at least in part, to a defect in endosperm function, which supports the parental conflict theory for the evolution of imprinting in plants and mammals.
