Reproduction Multitasking: The Male Gametophyte
Annual Review of Plant Biology, 2021 The gametophyte represents the sexual phase in the alternation of generations in plants; the other, nonsexual phase is the sporophyte. Here, we review the evolutionary origins of the male gametophyte among land plants and, in particular, its ontogenesis in flowering plants.

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.

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.

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.

• Premise of the study: Ferns and lycophytes are the only extant land plants with two free‐living generations (sporophytes and gametophytes); hence, a single species may have two different distributions. The distribution of the gametophytes of most fern species, which are much smaller in size than sporophytes, are almost unknown due to the difficulty ...

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,
