Abstract The European Alps show a high degree of endemism associated mainly with the location glacial refugia and environmental heterogeneity. Several Alpine endemics have evolved in genus Alyssum. Here we study perennial Alyssum populations Western Alps, distributed Aosta Valley region, which hosts species diversity, although are rare. We addressed recently described stenoendemic A. rossetii t...

Metal hyperaccumulator plants like Alyssum murale have a remarkable ability to hyperaccumulate Ni from soils containing mostly insoluble Ni. We have shown some rhizobacteria increase the phytoavailability of Ni in soils, thus enhancing Ni accumulation by A. murale. Nine bacterial strains, originally isolated from the rhizosphere of A. murale grown in serpentine Ni-rich soil, were examined for t...

Plant species were collected in the botanical-geographic regions of Lankaran-Mughan and Lankaran lowland located on sou­thern part Caspian coast. During ecological-geobotanical studies we conducted southern coast, obtained information about morphological features systematic taxa wild flora Lankaran-Mugan botanical-geographical regions.
