Differential expression of Lead accumulation during two growing seasons by desert shrub Acacia victoriae L.
In desert reclamation strainer plants can be used for improvement and decrease pollution of soil and water. This technology can be used to remove both inorganic and organic contaminants in soil. In this study, one year old Acacia victoriae seedlings were exposed to Pb (NO3)2 in 5 different concentrations; 0, 50, 250, 500 and 1000 mg Pb L-1 for 45 days in two growing seasons. Subsequently, the h...
متن کاملLight-dependent induction of proline biosynthesis by abscisic acid and salt stress is inhibited by brassinosteroid in <Emphasis Type="Italic">Arabidopsis</Emphasis>
Osmotic stress-induced accumulation of proline, an important protective osmolyte in higher plants, is dependent on the expression of 1-pyrroline-5-carboxylate synthase (P5CS) and proline dehydrogenase (PDH) enzymes that catalyze the rate-limiting steps of proline biosynthesis and degradation, respectively. Proline metabolism is modulated by differential regulation of organ specific expression o...
متن کاملQuantitative expression analysis of P5CS and BADH genes in cultivated wheat plants under salt and ABA treatments
Plants encounter various stresses such as drought and salinity which adversely affect growth, development and crop productivity. The expression of the genes Delta -1- pyr-roline – 5 - carboxylate synthetase (P5CS) and Betaine aldehyde dehydrogenase (BADH) extends throughout various protec-tive mechanisms in plants and allows them to adapt to unfavorable environmental condi-tions. P5CS and BADH ...
متن کاملProline accumulation and osmotic stress: an overview of P5CS gene in plants
Under osmotic stresses, proline accumulation is an important response of plants to these conditions. Proline is a compatible osmolyte which affects many cellular and molecular aspects of plant in both normal and stressful situations. Proline is shown to be involved in plant development in normal condition and in conferring resistance to plant under biotic and abiotic stresses. Therefore, many s...
متن کاملRole of abscisic acid (ABA) and Arabidopsis thaliana ABA-insensitive loci in low water potential-induced ABA and proline accumulation.
The mechanisms by which plants respond to reduced water availability (low water potential) include both ABA-dependent and ABA-independent processes. Pro accumulation and osmotic adjustment are two important traits for which the mechanisms of regulation by low water potential, and the involvement of ABA, is not well understood. The ABA-deficient mutant, aba2-1, was used to investigate the regula...
