Green fluorescent protein gene was conjugated to the 3 end of the PAP gene in order to screen easily of the transgenic cotton plants. The combined gene was cloned into plant expression vector pBI121 and then transformed. About 5000 seeds of the transgenic cotton were obtained and the some seedlings of the transgenic cotton could give a bright green fluorescence in the dark condition when the cotton seedlings were irradiated with ultraviolet rays. This result reflected that the GFP gene was expressed in the transgenic cotton; dot-blot result also demonstrated that PAP gene was exactly transformed into the cotton. The capacity of the Verticillium dahliae-resistance is being analyzed.

为了便于转基因棉花后代的筛选，在 PAP基因的 3'端融入了绿色荧光蛋白GFP）基因，然后将融合基因克隆在植物表达载体PBI 121上，再进行遗传转化，得转基因棉花种子5000余粒，将种子播种长到于叶展开时，先在黑暗中用紫外灯照射，查找表现绿色荧光的幼苗，然后再用地高辛标记的PAP基因特异性探针对这些棉花进行点杂交，最后发现有8株棉花表现阳性反应，说明PAP基因的确己经转到了棉花的基因组中，其棉花黄萎病的抗性鉴定正在进行之中。
