Insights into the evolutionary history and widespread occurrence of antheridiogen systems in ferns [PDF]
New Phytologist, 2021 Summary Sex expression of homosporous ferns is controlled by multiple factors, one being the antheridiogen system. Antheridiogens are pheromones released by sexually mature female fern gametophytes, turning nearby asexual gametophytes precociously male ...

Antheridiogen controls spatial dynamics of sex expression in naturally occurring gametophytes of the tree fern Cyathea multiflora. [PDF]
Am J Bot, 2022 Premise Antheridiogen systems are a set of pheromonal mechanisms that control sex expression in fern gametophytes. However, antheridiogen has rarely been studied outside of the laboratory, and little is known about its function in natural settings ...

Sex Determination in Ceratopteris richardii Is Accompanied by Transcriptome Changes That Drive Epigenetic Reprogramming of the Young Gametophyte [PDF]
G3: Genes, Genomes, Genetics, 2018 The fern Ceratopteris richardii is an important model for studies of sex determination and gamete differentiation in homosporous plants. Here we use RNA-seq to de novo assemble a transcriptome and identify genes differentially expressed in young ...

Reproduction and the pheromonal regulation of sex type in fern gametophytes. [PDF]
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,

Dynamic auxin maxima regulate male-to-hermaphrodite conversion and de novo meristem formation in the fern Ceratopteris gametophytes. [PDF]
PLoS BiologyLand plants alternate between generations of asexual sporophytes and sexual gametophytes. Unlike seed plants, ferns produce free-living gametophytes that grow independently from their sporophytes.

Cell division and lineage dynamics during antheridium differentiation and male gametophyte development in Ceratopteris richardii [PDF]
Communications BiologySexual reproduction in land plants involves diverse strategies for gamete production and fertilization, significantly differing between seed plants, which deliver sperm via pollen, and seed-free plants such as ferns, which produce motile sperm within ...

American Fern Journal, 2008 The gametophytic phase of several species of Pteris has been well studied, but for others, due perhaps to their more restricted distribution, little is known. Agar and soil cultures of different spore samples of P. incompleta were established in order to

Nutrient Levels Do Not Affect Male Gametophyte Induction by Antheridiogen in Ceratopteris richardii
American Fern Journal, 2009 —In the homosporous fern Ceratopteris richardii, sex is not determined chromosomally. Rather, hermaphroditic gametophytes produce a hormone called antheridiogen, which induces maleness in undifferentiated gametophytes.

Proteomic approaches to sexual development mediated by antheridiogen in the fern Blechnum spicant L
Proteomics, 2014 This report is intended to compare proteomic profiles between female and male gametophytes of Blechnum spicant L. For this purpose, female gametophytes were obtained from spores germinated on Murashige and Skoog medium (1962), and the male ones by ...
