Genetic Engineering for Salinity Stress Tolerance

摘要: Multiple biotic and abiotic environmental factors may constitute stresses that affect plant growth yield in crop species. With a focus on ionic stress exerted by the presence of sodium, associated water deficit, recent advances our understanding are reviewed. Established physiological, biochemical, genetic approaches made more meaningful inclusion genomics‐type tools, which have been most helpful making available global view transcriptome responses to salinity stress, providing lines from mutagenesis model species, particular for Arabidopsis thaliana. Many elements assure ion homeostasis transport become known, as several control homeostasis. Genes respond identified through mutant screens, comparative functional studies relied known physiological phenotypic parameters. Until now, resulting concepts strategies engineering tolerance their majority targeted single genes biochemical pathways, represent end points response cascades, but upstream master switches regulate activity many downstream proteins is increasingly attempted. The rapidly growing body results (salinity) sensing signaling promises lead identification those superior significance salt general.
