Salt-related Genes Expression Pattern in Salt-Tolerant and Salt-Sensitive Cultivars of Cotton (Gossypium sp.) under NaCl Stress
Salinity is one of the most important limitation factors in development of agricultural products. Cotton has a relative tolerance to salinity; however, salinity reduces its growth during germination and seedling stages. In this research, split-factorial design of time based on randomized complete block design with 3 replications was used. The real-time PCR results for, root, stem, and leaves of...
متن کاملSalt Tolerant and Sensitive Rice Varieties Display Differential Methylome Flexibility under Salt Stress
DNA methylation has been referred as an important player in plant genomic responses to environmental stresses but correlations between the methylome plasticity and specific traits of interest are still far from being understood. In this study, we inspected global DNA methylation levels in salt tolerant and sensitive rice varieties upon salt stress imposition. Global DNA methylation was quantifi...
متن کاملDevelopment and characterization of salt tolerant somaclones in rice cultivar pokkali.
Primary regenerants (1190) of a tall traditional salt tolerant rice cultivar pokkali were produced through in vitro culture from mature seed derived calli of fourth subculture. Out of 35000 SC2 regenerants, 26 promising lines with superior agronomic traits were chosen initially for evaluation. SC3 and SC4 generations were stringently evaluated under hydroponics with excess salt stress as well a...
متن کاملusing growth parameters for in-vitro screening of potato varieties tolerant to salt stress
salt stress negatively impacts crops yield throughout the world. nine varieties of potato (solanum tuberosum l.) were screened for salt stress tolerance by measuring in-vitro growth of the aerial plant parts, as well as roots. salt stress was evaluated by adding 25, 50, 75, 100, 125, 150 and 200 mm of nacl to murashige- skoog (ms) medium and compared to ms medium without nacl. plant length and ...
متن کاملAssessment of agro-physiological traits for salt tolerance in drought-tolerant wheat genotypes
Salt stress is one of the major constraints for wheat cultivation inIranand leads to a considerable loss in crop yield each year. In high salinity soils, the reduced osmotic potential of soil solutes may cause physiological drought. In this study the salt tolerance of different drought-tolerant bread wheat genotypes were studied by examining various agronomic and physiological traits, inclu...
