Population genomics of the eastern cottonwood (Populus deltoides)
Despite its economic importance as a bioenergy crop and key role in riparian ecosystems, little is known about genetic diversity and adaptation of the eastern cottonwood (Populus deltoides). Here, we report the first population genomics study for this species, conducted on a sample of 425 unrelated individuals collected in 13 states of the southeastern United States. The trees were genotyped by...
متن کاملMercuric ion reduction and resistance in transgenic Arabidopsis thaliana plants expressing a modified bacterial merA gene.
With global heavy metal contamination increasing, plants that can process heavy metals might provide efficient and ecologically sound approaches to sequestration and removal. Mercuric ion reductase, MerA, converts toxic Hg2+ to the less toxic, relatively inert metallic mercury (Hg0) The bacterial merA sequence is rich in CpG dinucleotides and has a highly skewed codon usage, both of which are p...
متن کاملBiochemical and Structural Properties of a Thermostable Mercuric Ion Reductase from Metallosphaera sedula
Mercuric ion reductase (MerA), a mercury detoxification enzyme, has been tuned by evolution to have high specificity for mercuric ions (Hg(2+)) and to catalyze their reduction to a more volatile, less toxic elemental form. Here, we present a biochemical and structural characterization of MerA from the thermophilic crenarchaeon Metallosphaera sedula. MerA from M. sedula is a thermostable enzyme,...
متن کامل’ Economics of Afforestation with Eastern Cottonwood (populus Deltoides) on Agricultural Land in the Lower
Higher prices for hardwood stumpage and changes in agricultural policies may favor afforestation on sites in the Lower Mississippi Alluvial Valley (LMAV) which are suitable for Eastern cottonwood (Popu/us de/toides Bartr.). We examined the potential returns to a landowner growing cottonwood on three soil classes common to the LMAV. We specified the conditions under which we think such afforesta...
متن کاملPlasmid-encoded mercuric reductase in Mycobacterium scrofulaceum.
A Chesapeake Bay water isolate of Mycobacterium scrofulaceum containing a 115-megadalton plasmid (pVT1) grew in the presence of 100 microM HgCl2 and converted soluble 203Hg2+ to volatile mercury at a rate of 50 pmol/10(8) cells per min. Cell extracts contained a soluble mercuric reductase whose activity was not dependent on exogenously supplied thiol compounds. The enzyme displayed nearly ident...
