Abstract:

In order to improve plant salt tolerance, full use of saline-alkali soil, through the use of Agrobacterium tumefaciens ultra xeric salt-tolerant plants Haloxylon (Haloxylon ammodendron) of betaine aldehyde dehydrogenase gene (HaBADH) into Japonica rice of Ningxia, its positive seedings to salt tolerance in plants related to physiological research. The results showed that high concentrations of NaCl (5.0, 7.0 g/L) stress, compared with the control, transfer HaBADH gene rice seedings superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) activity was significantly increased; malondialdehyde (MDA) levels were significantly reduced. The results showed that, transfer HaBADH gene could increase Japonica rice of Ningxia tolerance to salt stress.
