Transgenic Brassica napus plants overexpressing AtNHX1, a vacuolar Na + /H antiport from Arabidopsis thaliana, were able to grow, flower, and produce seeds in the presence of 200 mM sodium chloride. Although transgenic grown high salinity accumulated up 6% their dry weight, growth these was only marginally affected by salt concentration. Moreover, seed yields oil quality not soil. Our results demonstrate potential use for agricultural saline soils. findings, showing that modification single trait significantly improved tolerance this crop plant, suggest with combination breeding it could be possible salt-tolerant crops far fewer target traits than had been anticipated.
