马铃薯转 GhABF2转录因子苗耐盐性研究
Characteristics of salt tolerance capability of potato seedlings overexpressing GhABF2
摘要
Abstract
In order to improve adaptability of crops to adversity ,transgenic potato seedlings with GhABF2 gene were employed as study materials to investigate their drought tolerance capability .Results showed that under the conditions of NaCl stress ,two lines with GhABF2 transgene displayed similar variations to the control plants in terms of dry weight , fresh weight ,physiological and biochemical indexes .Based on the phenotypic variations ,it was found that the transgenic plants were significantly strong in drought resistance .With the increase of NaCl concentrations ,compared with non-trans-genic plants ,biomass of two transgenic plants appeared to be significantly increased .In addition ,with the increase of NaCl concentrations ,chlorophyll content of all seedlings investigated became decreased ,whereas soluble sugar ,MDA , proline ,SOD activity ,and POD activity all appeared to be increased .Soluble protein content did not display significant variations .On basis of the plant growth status and its physiological and biochemical indexes , two transgenic plants showed stronger resistance than non-transgenic plants .关键词
