Antioxidant enzymes Arabidopsis thaliana reactive oxygen species
2011/1/11
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...
Trehalose as Osmoprotectant for Maize Under Salinity-Induced Stress
Hill-reaction ion leakage K/Na ratio organic solutes photosynthetic pigments protein
2010/11/15
Response of maize grains (Giza 2) to the pre-soaking treatment with 10 mM trehalose was
studied under salinity-induced stress conditions. Trehalose treatment induced growth of salt-stressed and unstr...
