Glutathione status and its relationship to protein synthesis during water deficit and subsequent rehydration have been examined in the drought-tolerant moss, Tortula ruralis. During slow drying there is a small decrease in total glutathione but the percentage of oxidized glutathione (GSSG) increases. During rapid drying there is little change in total glutathione but a small increase in GSSG. O...

Taxonomic implications of the phylogeographic studies based on multilocus sequencing nuclear and chloroplast DNA regions Syntrichia sarconeurum, long considered to be Antarctic endemic moss species, are summarised. Molecular analyses confirmed conspecificity sarconeurum with S. lithophila pygmaea. This taxonomic conclusion implies that correct name for species in genus is a new synonym this nam...

The activities of glutathione reductase (EC 1.6.4.2), glutathione peroxidase (EC 1.11.1.9), and glutathione S-transferase (EC 2.5.1.18) were found to increase during slow drying or during rehydration following rapid drying of the drought-tolerant moss Tortula ruralis. Little change was observed in the activity of malate deydrogenase (NAD(+) oxidoreductase, EC 1.1.1.37) during dehydration or sub...

Desiccation-tolerance (DT) evolved as the key solution to survival on land by the early algal ancestors of terrestrial plants. This 'first' DT involved utilizing rapidly mobilisable repair mechanisms and is still found today in mosses, such as Tortula ruralis, and ferns, such as Mohria caffrorum. The first seed plants lost vegetative DT while investing their seeds with tolerance mechanisms impr...

Bu çalışma, Henderson (1961)’ın Türkiye kareleme sistemine göre B9 karesi içerisinde, şimdiye kadar yapraklı karayosunu (Bryophyta) ve ciğerotları (Marchantiophyta) ile ilgili yapılmış olan araştırmalara dayanan güncel bir listeyi içermektedir.

Jelen közlemény a Hernád menti kurgánok mohaflorisztikai vizsgálatának eredménye­it ismerteti. Összesen 41 taxon (1 májmoha és 40 lombosmoha) azonosítása történt meg vizsgált kilenc kunhalomról. Előfordulásuk száma alapján Brachythecium rutabulum, Tortulaacaulon var.acaulon Barbula unguiculata bizonyultak leggyakoribb mohafajoknak. További érdekes taxonok sírhalmokról: Acaulon muticum, triquetr...
