TL;DR: Results indicate a complex pattern of internal Cd allocation in P. × canescens resulting in higher ROS stress in wood than in bark and intermediate responses in roots and leaves, probably because of differential capacities of these tissues for the production of protective phenolic compounds.

TL;DR: The results suggest that orchestrated microstructural, transcriptomic, and physiological regulation may sustain cadmium hyperaccumulation in P. × canescens bark and provide new insights into engineering woody plants for phytoremediation.

TL;DR: It is concluded that P. cathayana (zhonghua 1) is superior to other five species for Cd phyto-remediation, and its well-coordinated physiological changes under Cd exposure confer the great Cd tolerance of this species.

TL;DR: The results suggest that growth, carbon and N physiology, and wood properties are more sensitive to increasing N availability in fast-growing poplars than in slow-growing ones, which is probably due to prioritized resource allocation to the leaves and accelerated N physiological processes infast-growingpoplars under higher N levels.

TL;DR: Net NH4+/NO3− fluxes and the interaction of net fluxes of both ions are tightly associated with H+ fluxes in poplar roots, indicating that root tips play a key role in NH4-/ NO3− uptake.
