UNLABELLED PREMISE OF THE STUDY The Sphagnopsida, an early-diverging lineage of mosses (phylum Bryophyta), are morphologically and ecologically unique and have profound impacts on global climate. The Sphagnopsida are currently classified in two genera, Sphagnum (peat mosses) with some 350-500 species and Ambuchanania with one species. An analysis of phylogenetic relationships among species a...
Most mosses have xerochastic dispersal (i.e., they open their capsules when conditions are dry), which is thought to favor long-distance dispersal. However, there are several species that use a hygrochastic strategy: spores are dispersed when conditions are wet. The significance of this strategy in the Mediterranean region is unknown. In this study, we explored whether ultrastructural features ...
Among land plants, angiosperms have the structurally most labile mitochondrial (mt) genomes. In contrast, the so-called early land plants (e.g., mosses) seem to have completely static mt chromosomes. We assembled the complete mt genomes from 12 mosses spanning the moss tree of life, to assess 1) the phylogenetic depth of the conserved mt gene content and order and 2) the correlation between sca...
The adsorption of copper on passive biomonitors (devitalized mosses Hypnum sp., Sphagnum denticulatum, Pseudoscleropodium purum and Brachythecium rutabulum) was studied under different experimental conditions such as a function of pH and Cu concentration in solution. Cu assimilation by living Physcomitrella patents was also investigated. Molecular structure of surface adsorbed and incorporated ...
