摘  要:
Harpin蛋白能激活植物的多种防卫通路,从而使植物产生对逆境的广谱抗性。hrf2编码Harpin_(Xooc)蛋白,具有与Harpin蛋白类似的功能。对转hrf2基因的大豆进行抗胞囊线虫病鉴定,结果表明:转hrf2基因大豆的2个株系的单株胞囊线虫数均极显著低于受体植株天隆一号,说明hrf2能够提高大豆对胞囊线虫病1号小种的抗性。

摘  要:
The Harpin protein could make plants produce broad-spectrum resistance to stress by activating the defense pathways of plants. Harpin_(Xooc) protein encoded by hrf2 gene has similar function to Harpin protein. In this study, the evaluation was performed to estimate the resistance to soybean cyst nematode(SCN) of transgenic soybean with hrf2 gene. The result showed that the SCN number of two lines of transgenic soybean with hrf2 gene was significantly lower than that of the receptor plant Tianlong 1, indicating that hrf2 gene might improve soybean resistance to SCN race 1.
