Salt tolerance in Salicornia
Salinization of agricultural land is an increasing problem. Because of their high tolerance to salinity, Salicornia spp. could become model species to study salt tolerance. Moreover, they also represent promising saline crops. The salinity-growth response curve for Salicornia dolichostachya Moss was evaluated at 10 different salt concentrations in a hydroponic study in a greenhouse and at 5 dif...
متن کاملCandidate salt tolerance genes in Salicornia
To date, no gene expression comparisons have been conducted between highly salt tolerant halophytes and related glycophytes. Therefore, I investigated the effects of salinity on ion accumulation and expression of candidate salt tolerance genes in the highly tolerant salt accumulating halophyte Salicornia dolichostachya and the taxonomically related glycophytic Spinacia oleracea. S. dolichostach...
متن کاملMechanisms of salinity tolerance.
The physiological and molecular mechanisms of tolerance to osmotic and ionic components of salinity stress are reviewed at the cellular, organ, and whole-plant level. Plant growth responds to salinity in two phases: a rapid, osmotic phase that inhibits growth of young leaves, and a slower, ionic phase that accelerates senescence of mature leaves. Plant adaptations to salinity are of three disti...
متن کاملSalinity Stress and Salt Tolerance
Salinity is one of the most serious factors limiting the productivity of agricultural crops, with adverse effects on germination, plant vigour and crop yield (R Munns & Tester, 2008). Salinization affects many irrigated areas mainly due to the use of brackish water. Worldwide, more than 45 million hectares of irrigated land have been damaged by salt, and 1.5 million hectares are taken out of pr...
متن کاملSalt and Crops: Salinity Tolerance
Soils are delicate structures, and careless agricultural practices can destroy them. Crop decline resulting from increased soil salinity can be traced back thousands of years to Sumer and Babylonia. There, the original “Fertile Crescent” eventually turned into desert, destroyed by deforestation, unwise planting, and irrigation-induced soil salinity. Such decline in soil productivity also was ev...
