tortula/atrophy

The response of the drought-tolerant moss Tortula ruralis ([Hedw.] Gaertn., Meyer, Scherb.) to freezing and thawing at controlled rates has been studied. Slow freezing (at 3 C per hour to -30 C) of hydrated T. ruralis leads to only temporary, reversible changes in metabolism. These changes can be

We isolated a dehydrin-like (DHN-like) gene fragment, PpDHNA, from the moss Physcomitrella patens by PCR amplification using degenerate primers directed against conserved amino acid segments of DHNs of higher plants. The full-length cDNA was found to encode a 59.2-kDa glycine-rich protein, DHNA,

Desiccation-tolerant plants are able to withstand dehydration and resume normal metabolic functions upon rehydration. These plants can be dehydrated until their cytoplasm enters a 'glassy state' in which molecular mobility is severely reduced. In desiccation-tolerant seeds, longevity can be enhanced
