As antioxidants, tocopherols deactivate reactive oxygen species and prevent lipids from oxidation in response to abiotic stresses. γ-Tocopherol methyltransferase (γ-TMT) catalyzes the conversion of γ-tocopherol into α-tocopherol which has the highest biological activity. To investigate roles of γ-TMT in seed germination under salinity stress, we heterologously overexpressed an alfalfa MsTMT gene in Arabidopsis. MsTMT transgenic seeds germinated much slower than that of Arabidopsis wild-type...[Show more]
