Plant chitinase responses to different metal-type stresses reveal specificity.

Chitinases in Glycine max roots specifically respond to different metal types and reveal a polymorphism that coincides with sensitivity to metal toxicity. Plants evolved various defense mechanisms to cope with metal toxicity. Chitinases (EC 3.

Defense responses of soybean roots during exposure to cadmium, excess of nitrogen supply and combinations of these stressors.

Heavy metal pollution is a serious environmental problem in agricultural soils since the uptake of heavy metals by plants represents an entry point into the food chain and is influenced by the form and amount of nitrogen (N) fertilization. Here we studied the defense responses in soybean roots exposed to ions of cadmium (applied as 50 mg l(-1) Cd(2+)) when combined with an excessive dose of N in form of NH(4)NO(3). Our data indicate that despite of stunted root growth, several stress symptoms typically observed upon cadmium treatment, e.

Characterization of variable EST SSR markers for Norway spruce (Picea abies L.).

Background: Norway spruce is widely distributed across Europe and the predominant tree of the Alpine region. Fast growth and the fact that timber can be harvested cost-effectively in relatively young populations define its status as one of the economically most important tree species of Northern Europe. In this study, EST derived simple sequence repeat (SSR) markers were developed for the assessment of putative functional diversity in Austrian Norway spruce stands.

One dry summer: a leaf proteome study on the response of oak to drought exposure.

One of the most prominent hallmarks of the expected climate change in Europe is the higher prevalence of longer and more intense periods of summer drought. To preserve European oak forests, of considerable importance for European economical and ecological development, under these conditions knowledge on the mechanisms by which broad-leaved trees cope with drought is needed. In this study the effect of one season of drought stress, corresponding in length and soil water content to a dry summer, on young pedunculate oak trees (Quercus robur L.
