Reproduction and the pheromonal regulation of sex type in fern gametophytes.
Frontiers in Plant Science, 2015 The fern life cycle includes a haploid gametophyte that is independent of the sporophyte and functions to produce the gametes. In homosporous ferns, the sex of the gametophyte is not fixed but can vary depending on its social environment. In many species,

Transcriptome analysis of haploid male gametophyte development in [PDF]
, 2004 Background: The haploid male gametophyte generation of flowering plants consists of two- or three-celled pollen grains. This functional specialization is thought to be a key factor in the evolutionary success of flowering plants.

NADPH OXIDASE-DEPENDENT SUPEROXIDE PRODUCTION IN PLANT REPRODUCTIVE TISSUES
Frontiers in Plant Science, 2016 In the life cycle of a flowering plant, the male gametophyte (pollen grain) produced in the anther reaches the stigmatic surface and initiates the pollen-pistil interaction, an important step in plant reproduction, which ultimately leads to the delivery ...

Defensin-like ZmES4 mediates pollen tube burst in maize via opening of the potassium channel KZM1. [PDF]
PLoS Biology, 2010 In contrast to animals and lower plant species, sperm cells of flowering plants are non-motile and are transported to the female gametes via the pollen tube, i.e. the male gametophyte. Upon arrival at the female gametophyte two sperm cells are discharged

Frontiers in Plant Science, 2022 Arabinogalactan proteins (AGPs) are hydroxyproline-rich glycoproteins containing a high proportion of carbohydrates, widely distributed in the plant kingdom and ubiquitously present in land plants. AGPs have long been suggested to play important roles in

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

PLoS Genetics, 2018 Gametophytic development in Arabidopsis depends on nutrients and cell wall materials from sporophytic cells. However, it is not clear whether hormones and signaling molecules from sporophytic tissues are also required for gametophytic development. Herein,
