We developed and tested 14 new polymorphic microsatellite loci for dreissenid mussels, including the two species that have invaded many freshwater habitats in Eurasia and North America, where they cause serious industrial fouling damage and ecological alterations. These new loci will aid our understanding of their genetic patterns in invasive populations as well as throughout their native Ponto...

Distribution Endemic to the six largest Ha-waiian islands. Size Greatly variable, typically reaches 20–24 m (66–79 ft) in height; may be much smaller on lava rock or boggy soils. Habitat Wide range, 1–2500 m (1–8200 ft) elevation with rainfall of 400–10,000 mm (16–400 in). Largest component of lowland and mon-tane wet and mesic forests, dry forests, subal-pine shrublands, and new lava flows. Ve...

In the yeast Hansenula polymorpha the development and turnover of peroxisomes is readily achieved by manipulation of the cultivation conditions. The organelles massively develop when the cells are incubated in the presence of methanol as the sole source of carbon and energy. However, they are rapidly and selectively degraded when methanol-grown cells are placed at conditions of repression of me...

In this study, for the first time, using similar methods, we compared the population density and distribution across different substrate types of Limnoperna fortunei andDreissena polymorpha, as well as their impacts on the composition of benthic communities. Data on L. fortunei were obtained in Rio Tercero Reservoir, Argentina, whereas studies on D. polymorpha were conducted in North America an...

BACKGROUND The detection and quantification of uric acid in human physiological fluids is of great importance in the diagnosis and therapy of patients suffering from a range of disorders associated with altered purine metabolism, most notably gout and hyperuricaemia. The fabrication of cheap and reliable urate-selective amperometric biosensors is a challenging task. RESULTS A urate-selective ...

Ensifer meliloti WSM1022 is an aerobic, motile, Gram-negative, non-spore-forming rod that can exist as a soil saprophyte or as a legume microsymbiont of Medicago. WSM1022 was isolated in 1987 from a nodule recovered from the roots of the annual Medicago orbicularis growing on the Cyclades Island of Naxos in Greece. WSM1022 is highly effective at fixing nitrogen with M. truncatula and other annu...

In eukaryote cells various mechanisms exist that are responsible for the removal of non-functional proteins. Here we show that in the yeast Hansenula polymorpha (H. polymorpha) a peroxisomal Lon protease, Pln, plays a role in degradation of unfolded and non-assembled peroxisomal matrix proteins. In addition, we demonstrate that whole peroxisomes are constitutively degraded by autophagy during n...
