| 摘 要： | 为了提高三倍体毛白杨的生根能力,把rolB基因转入三倍体毛白杨中,获得20个转化植株,在无激素培养基上,转化植株的生根率达到100%,而未转化植株的生根率只有15%~20%。PCR扩增证明目的基因已经插入到植物的基因组中。对部分rolB基因转化植株进行了GUS组织化学染色检测,转化植株叶片中有GUS活性的表达。

| Abstract: | To improve the rooting ability of the triploid Populus tomentosa,the rolB gene was transformed into the plant and 20 transgenic clones were obtained.The in vitro rooting results showed that the rooting rate of transgenic clones recheached 100% without auxin,while only 15% to 20 % for those without transformation.PCR analysis confirmed the integration of rolB gene sequence in the transformed plants.The leaves from part of pCMB-B:GUS transformed plants were analyzed for GUS gene expression.Histochemical GUS a... |
