Adaptations to particular stresses may occur only in populations experiencing those stresses or may be widespread within a species. Nickel hyperaccumulation is viewed as an adaptation to high-Ni (serpentine) soils, but few studies have determined if hyperaccumulation ability is restricted to populations from high-Ni soils or if it is a constitutive trait found in populations on both high- and l...
A comprehensive set of transcript sequences of the heavy metal hyperaccumulator Noccaea caerulescens
The role of endophytic fungi isolated from different populations European Ni hyperaccumulators was investigated in regard to the microorganisms' ability enhance hyperaccumulation Noccaea caerulescens. Effects particular species on adaptation N. caerulescens excess were tested by co-cultivation with single strains fungi. Seven these had a positive effect plant biomass production, whereas two inh...
A phytochemical study on the bark of Neisosperma oppositifolia (Apocynaceae) yielded two new beta-carboline indole alkaloids, oppositinines A (1) and B (2), together with five known alkaloids, isoreserpiline, isocarapanaubine, vobasine, 10-methoxydihydrocorynantheol-N-oxide, and ochropposinine oxindole. Structural elucidation of 1 and 2 was performed using 2D NMR methods. Oppositinines A (1) an...
