Mechanisms of high salinity tolerance in plants.
Among abiotic stresses, high salinity stress is the most severe environmental stress, which impairs crop production on at least 20% of irrigated land worldwide. In response to high salinity stress, various genes get upregulated, the products of which are involved either directly or indirectly in plant protection. Some of the genes encoding osmolytes, ion channels, receptors, components of calci...
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 کاملHumic Acid Confers HIGH-AFFINITY K+ TRANSPORTER 1-Mediated Salinity Stress Tolerance in Arabidopsis
Excessive salt disrupts intracellular ion homeostasis and inhibits plant growth, which poses a serious threat to global food security. Plants have adapted various strategies to survive in unfavorable saline soil conditions. Here, we show that humic acid (HA) is a good soil amendment that can be used to help overcome salinity stress because it markedly reduces the adverse effects of salinity on ...
متن کاملIn silico analysis of high affinity potassium transporter (HKT) isoforms in different plants
BACKGROUND High affinity potassium transporters (HKTs) are located in the plasma membrane of the vessels and have significant influence on salt tolerance in some plants. They exclude Na(+) from the parenchyma cells to reduce Na(+) concentration. Despite many studies, the underlying regulatory mechanisms and the exact functions of HKTs within different genomic backgrounds are relatively unknown....
متن کاملThe Role of HKT Transporters in Salinity Tolerance of Tomato
Salinity stress is the most widespread and the most severe abiotic stress that plants face. More than 800 million hectares worldwide, representing more than 6% of world's land area, are affected by salinity. Tomato is one of the most important horticultural crops. However, due to the progressive salinization of irrigated land, areas for optimal growth of tomato are being reduced all over the wo...
