Proteomic and phosphoproteomic analysis of polyethylene glycol-induced osmotic stress in root tips of common bean (Phaseolus vulgaris L.)
Previous studies have shown that polyethylene glycol (PEG)-induced osmotic stress (OS) reduces cell-wall (CW) porosity and limits aluminium (Al) uptake by root tips of common bean (Phaseolus vulgaris L.). A subsequent transcriptomic study suggested that genes related to CW processes are involved in adjustment to OS. In this study, a proteomic and phosphoproteomic approach was applied to identif...
متن کاملComparing the effects of polyethylene glycol-induced drought stress and paclobutrazol on six cultivars of Medicago sativa
This investigation was carried out with the aim of determining the effect of polyethylene glycol 6000 (PEG; 0, 3%, 6% and 9% w/v) treatment on six cultivars of Medicago sativa. PEG treatment significantly decreased the germination index in cultivars of Isfahani, Hamedani, Bami, Baghdadi, Yazdi and Ghare-Medicago, with the highest reduction in Ghare-Medicago and Hamedani cultivars by about 50% a...
متن کاملEffect of silicon application on wheat seedlings growth under water-deficit stress induced by polyethylene glycol
Silicon is known to ameliorate the deleterious effects of drought on plant growth. We evaluated growth of wheat (Triticum aestivum L. CV. Chamran) under Water-Deficit Stress Induced by Polyethylene Glycol as affected by Si application. In this article, the effects of Si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (RWC), electrol...
متن کاملA stomatal optimization theory to describe the effects of atmospheric CO2 on leaf photosynthesis and transpiration.
BACKGROUND AND AIMS Global climate models predict decreases in leaf stomatal conductance and transpiration due to increases in atmospheric CO2. The consequences of these reductions are increases in soil moisture availability and continental scale run-off at decadal time-scales. Thus, a theory explaining the differential sensitivity of stomata to changing atmospheric CO2 and other environmental ...
متن کاملAerosol-induced thermal effects increase modelled terrestrial photosynthesis and transpiration
Previous studies suggest that the radiative effects of atmospheric aerosols (reducing total radiation while increasing the diffuse fraction) can enhance terrestrial productivity. Here, simulations using a regional climate/terrestrial biosphere model suggest that atmospheric aerosols could also enhance terrestrial photosynthesis and transpiration through an interaction between solar radiation, l...
