Although the calcium requirement of phytochrome-mediated fern spore germination and early rhizoid growth is well established, the calcium-binding proteins that serve as transducers for these responses are not known. Here we report the presence of annexin-like proteins in germinating spores of
Partial cDNAs encoding for myosin-like proteins from Anemia phyllitidis and Arabidopsis thaliana have been isolated using PCR technology. The deduced amino acid sequences show an average similarity up to 62% with known myosin heavy chain genes. From northern blot analysis we were able to estimate
An antheridiogen of Anemia mexicana Klotzsch has been partially characterized by combined gas chromatography-mass spectrometry and gas chromatography-Fourier transform/infra-red spectrometry. It is a C19-gibberellin(GA)-like compound with one carboxyl group, an exocyclic methylene group and a
Phytochrome controls several developmental steps during formation and differentiation of the fern gametophyte, including spore germination, morphogenesis of the gametophyte or differentiation of the sexual cells. To obtain information about the amino acid sequence and the regulation of phytochrome
