Arabidopsis Book, 2011 The angiosperm female gametophyte is critical for plant reproduction. It contains the egg cell and central cell that become fertilized and give rise to the embryo and endosperm of the seed, respectively. Female gametophyte development begins early in ovule development with the formation of a diploid megaspore mother cell that undergoes meiosis.

Ultrastructural study of the female gametophyte and the epistase in Cabombaceae and Nymphaeaceae
Flora - Morphology, Distribution, Functional Ecology of Plants, 2016 Abstract Ultrastructural studies on the female gametophyte are restricted to species at relatively derived positions in the angiosperm phylogenetic tree. Therefore, this topic remains mostly unknown for the early-divergent lineages, in which a four-celled megagametophyte is common.

Journal of Marine Science and Engineering, 2021 Multiannual delayed gametophyte cultures can stay vegetative for years, while also having the ability to grow. This study aims to investigate whether male and female multiannual delayed gametophyte strains of the species Saccharina latissima and Alaria ...

Cells, 2022 Utricularia nelumbifolia is a large carnivorous plant that is endemic to Brazil. It forms an extra-ovular female gametophyte, which surpasses the entire micropylar canal and extends beyond the limit of the integument and invades the placenta tissues. Due

Female Gametophyte Development [PDF]
THE PLANT CELL ONLINE, 2004 Early in their evolution, plants acquired a life cycle that alternates between a multicellular haploid organism, the gametophyte, and a multicellular diploid organism, the sporophyte. Angiosperms have both female and male gametophytes.

ABAP1 Plays a Role in the Differentiation of Male and Female Gametes in Arabidopsis thaliana
Frontiers in Plant Science, 2021 The correct development of a diploid sporophyte body and a haploid gametophyte relies on a strict coordination between cell divisions in space and time. During plant reproduction, these divisions have to be temporally and spatially coordinated with cell ...

MYB64 and MYB119 are required for cellularization and differentiation during female gametogenesis in Arabidopsis thaliana. [PDF]
PLoS Genetics, 2013 In angiosperms, the egg cell forms within the multicellular, haploid female gametophyte. Female gametophyte and egg cell development occurs through a unique process in which a haploid spore initially undergoes several rounds of synchronous nuclear ...

Frontiers in Plant Science, 2021 The glycine-rich domain proteins (GRDP) have been functionally implicated in the cell wall structure, biotic, and abiotic stress responses. However, little is known about GRDP genes in female gametophyte development of Arabidopsis.
