Reproductive Multitasking: The Female Gametophyte
Annual Review of Plant Biology, 2020Fertilization of flowering plants requires the organization of complex tasks, many of which become integrated by the female gametophyte (FG). The FG is a few-celled haploid structure that orchestrates division of labor to coordinate successful interaction with the sperm cells and their transport vehicle, the pollen tube.

Epigenetic Regulation of Plant Gametophyte Development
International Journal of Molecular Sciences, 2019 Unlike in animals, the reproductive lineage cells in plants differentiate from within somatic tissues late in development to produce a specific haploid generation of the life cycle—male and female gametophytes.

Male gametophyte in maize: Influences of the gametophytic genotype
Theoretical and Applied Genetics, 1976Size and variation in pollen samples were investigated in several successively selfed generations. A significant decrease in mean diameter of pollen grains accompanied inbreeding; also decreased variation in pollen size from individual plants was observed.

Male gametophyte development: a molecular perspective.
Journal of Experimental Botany, 2009 Pollen grains represent the highly reduced haploid male gametophyte generation in flowering plants, consisting of just two or three cells when released from the anthers.

The female gametophyte develops from the megaspore formed in the nucellar tissue of the ovule. The megaspore enlarges and after some mitotic divisions a small coenocyte differentiates. In general, a megagametophyte consists, after cytokinesis, of an egg apparatus, a central cell, and antipodal cells.

GAMETOPHYTE DEVELOPMENT IN FERNS
Annual Review of Plant Physiology and Plant Molecular Biology, 1999▪ Abstract The fern gametophyte has interested plant biologists for the past century because its structure and development is simple and amenable to investigation. Past studies have described many aspects of its development, including germination of the spore, patterns of cell division and differentiation, photomorphogenic or light-regulated responses,

THE GAMETOPHYTE OF SCHIZAEA DICHOTOMA
American Journal of Botany, 1967Fourteen collections of gametophytes of Schizaea dichotoma, corresponding to the broadest taxonomic circumscription of the species, are described from New Caledonia. The gametophyte is subterranean, mycorrhizic and non‐green. It is basically filamentous with uniseriate growing points each ending with an apical cell with a single transverse cutting face.

Gametophytic Apomixis: An Introduction
Apomixis, clonal reproduction through seed, is divided into sporophytic (nucellar embryony) and gametophytic apomixis. This book focuses on the latter type. Gametophytic apomixis, while rare, is taxonomically widespread, notably among grasses and Asteraceae. Detection methods have advanced significantly, employing flow cytometry and advanced microscopyPeter J, van Dijk, Tatyana, Radoeva
