Expression profiling is one of the most important tools for dissecting biological functions of genes and the upregulation or downregulation of gene expression is sufficient for recreating phenotypic differences. Expression divergence of genes significantly contributes to phenotypic variations. However, little is known on the molecular basis of expression divergence and evolution among rice geno...

screening methods that are effective in the early stage of growth will potentially provide the largest quantity of breeding material. although various screening methods under greenhouse have been proposed, potential effective approaches must be described a good correlation with results under field conditions. this study was aimed to assess the correlations between traits obtained from four salt...

this study was carried out in order to evaluate allelic diversity of microsatellite markers in qtl region for salinity tolerance on chromosome 10 in rice and evaluation of agronomical traits of some iranian rice cultivars in salinity stress along with two tolerant (pokkali) and sensitive (ir29) check varieties, and association analysis for morphological traits using microsatellite markers.based...

Salinity, along with drought, is one of the key abiotic stressors that has posed a danger to advancement and evolution cereal crops like rice wheat. Water shortage lack irrigation water availability are main causes salty soil formation. Rice salt sensitive glycophyte, wheat moderately tolerant. Wild tolerant cultivars Oryza coarctata alta more than traditional such as Pokkali Nona Bokra in rice...

Salinity is one of the major environmental factors limiting growth and productivity of crop plants in coastal areas and irrigated farmlands. Salinity tolerance is a very complex trait. Plants adapt to salinity stress by coordinated and orchestrated functioning of various complex mechanisms. In Arabidopsis thaliana, SOS (Salt Overly Sensitive) pathway has been established as a major player in io...

Soil salinity is one of the most challenging problems that restricts the normal growth and production of rice worldwide. It has therefore become very important to produce more saline tolerant rice varieties. This study shows constitutive over-expression of the vacuolar Na(+)/H(+) antiporter gene (OsNHX1) from the rice landrace (Pokkali) and attainment of enhanced level of salinity tolerance in ...
