摘要:

Bacillus subtilisstrain GB03 has been shown to confer salt tolerance inArabidopsis thaliana.In this study,the potential for GB03 to promote biomass accumulation and increase salt tolerance was investigated in wheat (Triticum aestivum). Soil-grown wheat seedlings were assayed for dry-weight increase. Endogenous Na+and K+contents weredetermined in plants with or without soil inoculation with GB03 along with 0, 25 or 100 mMNaCl solution added to thesoil. We demonstrated that the introduction of GB03 in the soil triggered wheat biomass accumulation. Furthermore,GB03 improved salt tolerance as measured by increased tissue mass, lower Na+accumulation and improved K+/Na+ratio when GB03-inoculated plants were grown under elevated salt conditions. This study provides insight for theapplication of selected bacteria to monocot crops to combat saline toxicity
