In the fern Adiantum capillus-veneris, the phototropic response of the protonemal cells is induced by blue light and partially inhibited by subsequent irradiation with far-red light. This observation strongly suggests the existence of a phytochrome that mediates this blue/far-red reversible response

We tested an idea that induced mutagenesis due to unrepaired DNA lesions, here the UV photoproducts, underlies the impact of UVB irradiation on plant phenotype. For this purpose we used protonemal culture of the moss Physcomitrella patens with 50% of apical cells, which mimics actively growing tissu

Fern-spore is a good single-cell model for studying the sophisticated molecular networks in asymmetric cell division, differentiation, and polar growth. Osmunda cinnamomea L. var. asiatica is one of the oldest fern species with typical separate growing trophophyll and sporophyll. The chlorophyllous
NACK Kinesin Is Required for Metaphase Chromosome Alignment and Cytokinesis in the Moss Physcomitrella Patens

… When we simultaneously knocked down three PpNACKs by RNA-interference (RNAi) in protonemal cells, we observed a cytokinesis failure following a defect in phragmoplast expansion. …
