Structure of an antheridiogen from the fern Anemia mexicana
Phytochemistry, 1989Abstract A new antheridiogen isolated from gametophytes of the fern Anemia mexicana has been determined to have the structure ent -1α,10β-dihydroxy-9α,15α-cyclo-20-norgibberell-16-ene-7,19-dioic acid 10,19-lactone.

3-epi-GA63, antheridiogen in Anemia phyllitidis
Phytochemistry, 19953-Epi-Gibberellin A (3-epi-GA) was identified by full-scan GC-mass spectrometry of a purified extract from culture media of prothallia of the fern, Anemia phyllitidis. This is the third antheridiogen, following antheridic acid and 3α-hydroxy-9,15-cyclo-GA, in this species.

The Antheridiogen Neighborhood of Polystichum acrostichoides (Dryopteridaceae) on a Native Substrate
International Journal of Plant Sciences, 1997Antheridiogens are water-soluble pheromones found in many species of homosporous ferns. They are produced by female gametophytes bearing notch meristems and induce precocious maleness as well as retard growth in ameristic neighbors. A natural soil substrate was used to examine the horizontal range of antheridiogen effects (i.e., antheridiogen ...

On the physiology and chemistry of fern antheridiogens
The Botanical Review, 1975Dopp has demonstrated an antheridium-inducing hormone (antheridiogen) in P.aquilinum. This antheridiogen (abbr. Apt.) is active in many, if not all, species of the family Polypodiaceae. Among responsive species, the minimally effective concentration varies widely.

Action and phylogeny of antheridiogens
Proceedings of the Royal Society of Edinburgh. Section B. Biological Sciences, 1985SynopsisEvolution of new forms of organisms must be accompanied by evolution of the informational processes which regulate the development of these new forms. During plant phylogeny, products of metabolism have become phytohormones through the evolution of receptor molecules.
