The SOS1 transporter of Physcomitrella patens mediates sodium efflux in planta

Physcomitrella patens

Arabidopsis and other species, this work has also begun to reveal the levels of evolutionary conservation within the flowering plants and even outside the plant kingdom. What does the future hold for Antirrhinum research? In addition to its continuing role as a genetic model for plant biology and development, several new experimental avenues are beginning to be explored with Antirrhinum. A majo...

Gene targeting in Physcomitrella patens.

Gene-targeting efficiency in the land plant Physcomitrella patens (Bryophyta) can only be compared with that observed in Saccharomyces cerevisiae. Sequencing programs and microbiological molecular genetic approaches are now being developed to unravel the precise function of plant genes. Physcomitrella patens, as the new 'green yeast', might well become a major tool for functional genomic studie...

Culturing the moss Physcomitrella patens.

This article includes a series of methods for culturing the moss Physcomitrella patens at all stages of its life cycle. Gametophytes are axenically cultured on solid agar-based media and in shaken liquid cultures. For long-term storage of gametophytes, cultures are maintained on solid medium at 10°C in a very short day. Cryopreservation may also be used. Finally, sporophytes are generated by se...

Update on Physcomitrella patens The Moss Physcomitrella patens, Now and Then

Mosses (Musci, Bryophytaea) are one of the oldest groups of land plants present among the earth’s flora. They originated 500 million years ago (for a recent discussion of the time scale involved, see Heckman et al., 2001) and are currently represented by approximately 10,000 species that colonize diverse habitats that range from high mountains to deep forests and from Antarctica to deserts. Evo...
