Responses of Plant Proteins to Heavy Metal Stress—A Review
Plants respond to environmental pollutants such as heavy metal(s) by triggering the expression of genes that encode proteins involved in stress response. Toxic metal ions profoundly affect the cellular protein homeostasis by interfering with the folding process and aggregation of nascent or non-native proteins leading to decreased cell viability. However, plants possess a range of ubiquitous ce...
متن کاملNitric oxide induces stomatal closure and enhances the adaptive plant responses against drought stress.
Nitric oxide (NO) is a very active molecule involved in many and diverse biological pathways where it has proved to be protective against damages provoked by oxidative stress conditions. In this work, we studied the effect of two NO donors, sodium nitroprusside (SNP) and S-nitroso-N-acetylpenicillamine SNP-treated on the response of wheat (Triticum aestivum) to water stress conditions. After 2 ...
متن کاملPlant Responses to Drought and Stress Tolerance
In the natural environment plants are well adapted to minimize damages which only occurs under extreme conditions. In the frame of “physiological window” mild drought induces in plants regulation of water loss and uptake allowing maintenance of their leaf relative water content within the limits where the photosynthetic capacity shows no or little changes. But severe drought induces in plants u...
متن کاملEvaluating the physiological and hormonal responses of caper plant (Capparis spinosa) subjected to drought and salinity
In order to investigate the effect of drought and salinity stress on caper plant (Capparis spinosa), a factorial experiment including two factors consisting of drought and salinity levels based on randomized complete block design (RCBD) with five blocks were carried out at College of Agriculture, Shiraz University, Shiraz, Iran. After pretreatment, seeds were germinated in petri dishes and then...
متن کاملPlant Responses to Heavy Metal Toxicity
Plants, like all other organisms, have evolved different mechanisms to maintain physiological concentrations of essential metal ions and to minimize exposure to non-essential heavy metals. Some mechanisms are ubiquitous because they are also required for general metal homeostasis, and they minimize the damage caused by high concentrations of heavy metals in plants by detoxification, thereby con...
