Genomics, Physiology, and Molecular Breeding Approaches for Improving Salt Tolerance.
Salt stress reduces land and water productivity and contributes to poverty and food insecurity. Increased salinization caused by human practices and climate change is progressively reducing agriculture productivity despite escalating calls for more food. Plant responses to salt stress are well understood, involving numerous critical processes that are each controlled by multiple genes. Knowledg...
متن کاملIn vitro screening for salt tolerance in Rice ( Oryza sativa )
An experiment was conducted to study the performance of rice genotypes for salt tolerance under in vitro condition. Seven genotypes include salt tolerant (Pokkali, CSR 10, TRY 1 and TRY2), moderately tolerant to salt (White Ponni and BPT 5204) and susceptible (IR 29) were used for this study through embryo culture technique. Callus was initiated in MS medium + 2 mgl 2,4D + 0.5 mgl Kin and diffe...

in this study, 40 genotypes and breeding lines in the vegetative stage was conducted in a factorial arrangement based on a complete randomized block design with 3 replications in greenhouse at sari university agricultural science and natural resource, iran, 2008. seventeen genotypes were selected and tested in seedling stage in 2009. the results showed that genotypes had significant difference ...
متن کاملEctopic Expression of OsSta2 Enhances Salt Stress Tolerance in Rice
Salt stress can severely reduce crop yields. To understand how rice (Oryza sativa) plants respond to this environmental challenge, we investigated the genes involved in conferring salt tolerance by screening T-DNA tagging lines and identified OsSta2-D (Oryza sativa Salt tolerance activation 2-Dominant). In that line, expression of OsSta2 was enhanced by approximately eightfold when compared wit...
متن کاملMolecular Breeding to Improve Salt Tolerance of Rice (Oryza sativa L.) in the Red River Delta of Vietnam
Rice is a stable food in Vietnam and plays a key role in the economy of the country. However, the production and the cultivating areas are adversely affected from the threats of devastation caused by the rise of sea level. Using marker-assisted backcrossing (MABC) to develop a new salt tolerance rice cultivar is one of the feasible methods to cope with these devastating changes. To improve rice...
