effect of exogenous application of proline and glycine betaine on biochemical alterations in grapevine under drought stress
proline and glycine betaine are the most common compatible solutes that prevent plants from destructive effects of osmotic stresses by osmotic adjustment and protection of membranes, proteins and enzymes. it has been reported that exogenous application of these compounds, can increase plant resistance to drought stress. therefore a factorial experiment based on randomized complete block design ...
متن کاملeffect of proline and glycine betaine application on some physiological characteristics in grapevine under drought stress
drought, as an abiotic stress inflicts destructive and harmful effects on plants at their different growth stages. plants react differently to drought. among their reactions is the production of such osmolytes as proline and glycine betaine. it seems that, through exogenous application of these materials, plant resistance to drought stress can be increased. therefore, a factorial experiment, ba...
متن کاملGenetic engineering of glycine betaine biosynthesis to enhance abiotic stress tolerance in plants
Glycine betaine (GB) is an important compatible solute that protects plants against the damaging effects of abiotic stresses. A number of plants have been engineered to contain genes of the GB biosynthetic pathway, which confers enhanced tolerance to a range of abiotic stresses during various plant developmental stages. Unlike natural accumulators, the transgenic plants accumulate very low GB c...
متن کاملCompatible Solute Engineering in Plants for Abiotic Stress Tolerance - Role of Glycine Betaine
Abiotic stresses collectively are responsible for crop losses worldwide. Among these, drought and salinity are the most destructive. Different strategies have been proposed for management of these stresses. Being a complex trait, conventional breeding approaches have resulted in less success. Biotechnology has emerged as an additional and novel tool for deciphering the mechanism behind these st...
متن کاملDissecting the Role of Glycine Betaine in Plants under Abiotic Stress
Among the compatible solutes, glycine betaine (GB) is particularly an effective osmolyte against abiotic stress. Metabolic acclimation of GB is regarded as a basic strategy for the protection and survival of plants in harsh environmental conditions. Plant species vary in their capacity to synthesize GB. Some plants, such as spinach and barley, accumulate relatively higher levels of GB in their ...
