Sexual and Apogamous Species of Woodferns Show Different Protein and Phytohormone Profiles [PDF]
Frontiers in Plant Science, 2021 The gametophyte of ferns reproduces either by sexual or asexual means. In the latter, apogamy represents a peculiar case of apomixis, in which an embryo is formed from somatic cells.

Comparative transcriptome analysis of two reproductive modes in Adiantum reniforme var. sinense targeted to explore possible mechanism of apogamy [PDF]
BMC Genetics, 2019 Background Apogamy is a unique asexual reproduction in the ferns, in which somatic cells of gametophytes go through dedifferentiation and then differentiate into haploid sporophytes bypassing fertilization.

In vitro culture and apogamy: Alternative pathway in the life cycle of the moss Amblystegium serpens (Amblystegiaceae) [PDF]
Archives of Biological Sciences, 2005 In vitro culture of the moss Amblystegium serpens (Amblystegiaceae) was established on hormone-free Murashige and Skoog (MS) medium that contained a half amount of MS micro- and macro- mineral salts and vitamins, 100 mg/l myoinositol, 30 g/l sucrose, and

RESEARCHES CONCERNING THE IN VITRO DIFFERENTIATION OF THE FERN PHEGOPTERIS CONNECTILIS (MICHX.) WATT
Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2007 Phegopteris connectilis is an apogamous species, endangered in certain regions. The ex situ conservation, through the in vitro production of the gametophyte, as well as the embryos and the plants, followed by their cryo-stocking, is necessary for ...

In Vitro Development of Gametophyte and Sporophyte in Several Fern Species
Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2008 The in vitro differentiation of the gametophyte and sporophyte of Pteridophyta, conducted through the culture, on nutritive media, of the green, incompletely differentiated sporangia and spores, exhibits a variety of peculiarities. Whereas in the case of
