Involvement of nitric oxide synthase-dependent nitric oxide and exogenous nitric oxide in alleviating NaCl induced osmotic and oxidative stress in Arabidopsis thaliana

To elucidate the roles of endogenous nitric oxide on Arabidopsis thaliana tolerance to salt stress, a moderate concentration of NaCl was applied to wild-type (WT) and mutant (Atnoa1) plants which have an impaired in vivo nitric oxide synthase and reduced endogenous nitric oxide content due to T-DNA insertion in the first exon of the NOA1 gene. The exhibited greater inhibition of root growth, higher leaf...
