Global warming in polar regions brings a risk of more frequent and long-lasting dry periods due to warmer windier climate during summers. Mosses are well adapted desiccation-rehydration events they have evolved remarkable constitutive inducible mechanisms desiccation tolerance. In our study, Sanionia uncinata Racomitrium lanuginosum were collected Svalbard used for laboratory-based repetitive 3...

Cyanobacteria-plant symbioses play an important role in many ecosystems due to the fixation of atmospheric nitrogen (N) by the cyanobacterial symbiont. The ubiquitous feather moss Pleurozium schreberi (Brid.) Mitt. is colonized by cyanobacteria in boreal systems with low N deposition. Here, cyanobacteria fix substantial amounts of N₂ and represent a potential N source. The feather moss appears ...

The goal of The William and Flora Hewlett Foundation‟s Global Development Program is to improve the income and well-being of people living on less than $2 per day. The Program seeks to promote specific changes that will help reduce extreme poverty in a set of target countries. To achieve this goal, the Global Development Program will invest in three complementary drivers of economic growth: (1)...

BACKGROUND AND AIMS Moss roses are old garden roses covered with a mossy growth on flower pedicel and calyx. This moss releases a pine-scented oleoresin that is very sticky and odoriferous. Rosa x centifolia 'muscosa' was the first moss rose to be obtained by bud-mutation but, interestingly, R. x damascena 'Quatre Saisons Blanc Mousseux' was the first repeat-blooming cultivar, thus interesting ...

We present here the concept of "in-plant" NMR and show that high-resolution NMR spectroscopy is suitable for the analysis of intact plants and can be used to follow the changes in the intraorganismal molecular composition over long time periods. The NMR-based analysis of the effect of different concentrations of heavy water on the aquatic plant Vesicularia dubyana revealed that due to the prese...
