Poplar demand.
Trichloroethylene (TCE) is a common industrial solvent that poses a particular pollution problem in groundwater; while TCE disappears from surface water within a few weeks, groundwater contamination can take months or years to degrade. Humans have not conclusively been shown to develop cancer in response to TCE exposure, but rats and mice exposed to TCE have an increased incidence of liver and ...
متن کاملTranspirational demand affects aquaporin expression in poplar roots
Isohydric plants tend to maintain a water potential homeostasis primarily by controlling water loss via stomatal conductance. However, there is accumulating evidence that plants can also modulate water uptake in a dynamic manner. The dynamics of water uptake are influenced by aquaporin-mediated changes in root hydraulics. Most studies in this area have been conducted on herbaceous plants, and l...
متن کاملInfluence of evaporative demand on aquaporin expression and root hydraulics of hybrid poplar.
When light levels and evaporative demand increase, dynamic physiological changes in roots may be required to restore the water balance at the whole plant level. We hypothesized that a dynamic increase in root hydraulic conductance (L(P)) and aquaporin (AQP) expression could moderate the transpiration-induced drop in water potential (Ψ), allowing continued gas exchange in hybrid poplar (Populus ...
متن کاملThe Poplar-Poplar Rust Interaction: Insights from Genomics and Transcriptomics
Poplars are extensively cultivated worldwide, and their susceptibility to the leaf rust fungus Melampsora larici-populina leads to considerable damages in plantations. Despite a good knowledge of the poplar rust life cycle, and particularly the epidemics on poplar, the perennial status of the plant host and the obligate biotrophic lifestyle of the rust fungus are bottlenecks for molecular inves...
متن کاملPoplar (Populus spp.).
Although species within the genus Populus are, in general, easier to transform and regenerate in vitro than most other trees, many poplar species are very recalcitrant. Many protocols that previously have been reported were developed for a specific genotype or species. Thus, it has often been necessary to re-optimize a protocol each time research is initiated with a new genotype. The method pre...
