Abiotic Stress Tolerance in Plants with Emphasizing on Drought and Salinity Stresses in Walnut
Drought and salt stress, together with low temperature, are major problems for agriculture because these adverse environmental factors prevent plants from realizing their full genetic potential. Salt stress afflicts agriculture in many parts of the world, particularly irrigated lands [4]. Compared to salt stress, the problem of drought is even more pervasive and economically damaging [1; 3]. Te...
متن کاملPhysiology and molecular biology of salinity stress tolerance in plants
The productivity of plants is greatly affected by various environmental stresses. Soil salinity affects plant growth and development by way of osmotic stress, injurious effects of toxic Na and Cl – ions and to some extent Cl – and SO4 2 – of Mg and nutrient imbalance caused by excess of Na and Cl – ions. Salinity stress response is multigenic, as a number of processes involved in the tolerance ...
متن کاملGenomics Approaches For Improving Salinity Stress Tolerance in Crop Plants
Salinity is one of the major factors which reduces crop production worldwide. Plant responses to salinity are highly complex and involve a plethora of genes. Due to its multigenicity, it has been difficult to attain a complete understanding of how plants respond to salinity. Genomics has progressed tremendously over the past decade and has played a crucial role towards providing necessary knowl...
متن کاملGenetics of Drought Stress Tolerance in Crop Plants
Ensuring stable crop yields in an era where climate change threatens traditional agricultural practices through altered rainfall patterns and increased urban consumption has become a vital concern in global food security. Projected freshwater availability for irrigation indicates that between 20 and 60 Mha of irrigated cropland may have to be reverted to rainfed management [57]. Formerly irriga...
متن کاملEngineering drought and salinity tolerance in plants: lessons from genome-wide expression profiling in Arabidopsis.
World food security is increasingly dependent on continuous crop improvement and, in particular, the development of crops with increased drought and salinity tolerance. The completed genomic sequence of the model plant Arabidopsis thaliana and the development of whole-genome microarrays, together with increasing repositories of publicly available data and data analysis tools, have opened new av...
