Isolation and identification of antheridiogens in the ferns, Lygodium microphyllum and Lygodium reticulatum

Antheridiogens in culture media of 6-week-old prothallia of two species of Schizaeaceous ferns, Lygodium microphyllum and Lygodium reticulatum, were analyzed by gas chromatography-mass spectrometry. In both species, the gibberellin A sub73 methyl ester (GA sub73 -Me) was identified as the most abund...

Description
Summary:Antheridiogens in culture media of 6-week-old prothallia of two species of Schizaeaceous ferns, Lygodium microphyllum and Lygodium reticulatum, were analyzed by gas chromatography-mass spectrometry. In both species, the gibberellin A sub73 methyl ester (GA sub73 -Me) was identified as the most abundant antheridiogen, and the methyl esters of GA sub9 and of several monohydroxy-GA sub73 derivatives were also detected. Since both species produced antheridiogens at a high level, they were classified into high-antheridiogen-producing ferns. The response to GA sub73 -Me of gametophytes of both species is also discussed.
