15 صفحه اولEffects of two iron sources on iron and cadmium allocation in poplar (Populus alba) plants exposed to cadmium.
Effects of 10 microM cadmium (supplied as Cd nitrate) on the utilization and allocation of iron (Fe) were investigated in poplar (Populus alba L.) plants grown in nutrient solution with Fe(III)-EDTA or Fe(III)-citrate as the Fe source. The effects of Cd were also compared with those of Fe deprivation. The accumulation of Fe in roots was 10-fold higher in plants grown with Fe-citrate than with F...
متن کاملRapidly Evolving Genes and Stress Adaptation of Two Desert Poplars, Populus euphratica and P. pruinosa
Understanding which genes have evolved rapidly with the recent tree speciation in arid habitats can provide valuable insights into different adaptation mechanisms. We employed a comparative evolutionary analysis of expressed sequence tags (ESTs) from two desert poplars, Populus pruinosa and P. euphratica, which diverged in the recent past. Following an approach taken previously with P. euphrati...

Cavitation vulnerability in roots and shoots: does Populus euphratica Oliv., a poplar from arid areas of Central Asia, differ from other poplar species?
Populus euphratica is a poplar species growing in arid regions of Central Asia, where its distribution remains nevertheless restricted to river-banks or to areas with an access to deep water tables. To test whether the hydraulic architecture of this species differs from that of other poplars with respect to this ecological distribution, the vulnerability to cavitation of P. euphratica was compa...
