Response to cadmium in higher plants
It is proposed that, above all in response to acute cadmium stress, various mechanisms might operate both in an additive and in a potentiating way, and a holistic and integrated approach seems to be necessary in the study of the response of higher plants to Cadmium. Expand
Overexpression of Arabidopsis phytochelatin synthase in tobacco plants enhances Cd2+ tolerance and accumulation but not translocation to the shoot
The increase in Cd2+ tolerance and accumulation of PCS1 overexpressing plants is directly related to the availability of GSH, while overexpression of phytochelatin synthase does not enhance long distance root-to-shoot Cd 2+ transport. Expand
Phytochelatins govern zinc/copper homeostasis and cadmium detoxification in Cuscuta campestris parasitizing Daucus carota
This work showed that Cuscuta campestris Yuncker establishes effective haustorial connections with leaf petioles and blades of Daucus carota L. (carrot), with the consequent transfer of Cd and essential metals from the host vascular bundles to the parasite, and detected the presence in the parasite of significant amounts of glutathione and phytochelatins.

Lichens respond to heavy metals by phytochelatin synthesis
The trebouxioid lichens may gain an ecological advantage from their capability to counter heavy metal stress with prompt phytochelatin synthesis. Expand
Response to cadmium in carrot in vitro plants and cell suspension cultures
In vitro grown plants and cell suspension cultures of carrot were treated with various Cd concentrations and absence of ethylene caused both a decrease in the phytochelatin synthase activity of cell suspensions and a strong lowering in the Cd-induced SH groups in plants. Expand
The morphogenic responses and phytochelatin complexes induced by arsenic in Pteris vittata change in the presence of cadmium
Data show that Cd alters the natural capabilities of the fern to hyperaccumulate As, but also suggest that P.vittata is able to contrast the toxicity due to As plus Cd, at least within defined limits. Expand
Response to Heavy Metals in Plants: A Molecular Approach
Heavy metal pollution causes a number of toxic symptoms both in higher plants and algae, e.g. growth retardation, inhibition of photosynthesis, induction and inhibition of enzymes, generation ofExpand
Metal chelating peptides and proteins in plants
A group of metals having a density higher than 5 g cm−3 are generally termed as heavy metals (HM) and are toxic to plants when available in excess. However, a subset of them, at low concentrations,Expand
Elevated atmospheric CO2 decreases oxidative stress and increases essential oil yield in leaves of Thymus vulgaris grown in a mini-FACE system
Abstract Potted one-year-old plants of Thymus vulgaris L. (thyme, Lamiaceae, C3 metabolism), were grown for three months (10 June–10 September, 2004) in a “mini-free-air-CO 2 -enrichment”Expand
