Abstract:
Salinity is one of the major environmental factors that limit the worldwide productivity and distribution of crops. In plants one of the main mechanisms to overcome unfavorable environmental factors, such as water deficit and high salinity, is the accumulation of organic compounds of low molecular weight known as compatible solutes.
Which biosynthetic pathways one of them is glycinebetaine have been characterized in higher plants and in microorganisms.
In Uzbekistan salinity is one of the major problem for plant breeders. Taking the above into consideration, development of salt tolerant crops in Uzbekistan is of great importance and development of local commercial salt tolerant crop varieties prioritized.
Moreover, improved tolerance of glycinebetaine-biosynthetic transgenic plants (cotton, maize and wheat) have been observed only to water stress. There are no reports about improved tolerance of GB transgenic plants (mentioned above) to salinity.
Since a number of salt tolerance genes have been characterized in some plant species. We designed degenerative primers for plant salt tolerance genes (SOS1, SOS 3 and HKT 1) to identify and characterize their homologs in genomes of cotton species.
Moreover, genetic construct of modified codA gene from A.globiformis is under development. This construct will be used for development of local salt tolerant crop varieties.
