Molecular and biochemical responses to salinity. Functionality of aquaporins

Objective

Salinity constitutes the most severe agricultural problem in many parts of the world and is the major factor limiting crop production. For this reason, plant response to salinity is one of the most widely researched subjects in plant physiology. Aquaporins are membrane channel proteins that facilitate the permeation of water across biological membranes. Water relations are rather complex and aquaporin regulation can be one of the mechanisms for optimal water balance under changing environmental and developmental conditions.

In this project we will determine the biochemical and molecular mechanisms involves in water uptake in different plants irrigated with water containing high salinity level. Therefore, we will study the tolerance to salinity in pepper plan ts and for this, we will try to isolate and characterize some aquaporin genes in pepper plants and study the changes in their expression under different stress conditions. Changes in membrane water permeability may part of a general response to various abiotic and biotic stresses, such as pathogen attack or oxidative damage and may be related to aquaporin activation or inactivation.

In consequent, we will analyse the effect of H2O2 in aquaporins regulation and the correlation between the oxidative stress and aquaporin functionality. In order to elucidate the aquaporins function, the effect of virus on their regulation will be studied.
