The results showed that the wheat growth was increased with lower concentration of Cu; but with higher concentration of Cu, the activities of diastase and the mitotic index of root tip cell of wheat were reduced, the content of pro was increased.

朱云集等研究了Cu对小麦根系生长发育及生理特性的影响，指出随Cu浓度的提高，小麦胚根、次生根条数减少，根系SOD与POD活性呈下降趋势[7]。

Three kinds of plant expressing vector pC1304- CamV35S+ Cbcor15b, pC1304-cold-induced promotor+ Cbcor15b*, pC1304- CamV35S+ Cbcbf for transforming dicotyledon plants was constructed successfully by substituting the report gene of pC1304 with the coding sequence of our destination gene. The recombinant vector was introduced into Agrobacterium tumefaciens with freeze-thaw method. The leaf discs of tobacco plants infected by A. tumefaciens were selected with hygromycin. The regenerated plants were tested by PCR.

The best optimum conditions of the Agrobacterium mediated genetic transfornation were that leaves explants were immersed in the diluter 10 times Agrobacterium bacilli at OD600 of 0.6 for 8 minutes after being pre-cultured for 2 days,and then co-cultivated for 3 days.Then these explants were transferred to selected and rooting medium which contained 50 mg/L Kanamycin and 500 mg/L Carbenicillin.According to the transformation system, 54 transgenic plants were initially screened,then after PCR analysis and RT-PCR analysis 25 transgenic plants were obtained.

根癌农杆菌介导的芪合酶基因遗传转化的最佳条件为：将预培养2 d的烟草外植体，用稀释10倍的GV3101菌株菌液（OD600=0.6）浸染8 min后，共培养3 d，然后转入含卡那霉素50 mg/L和羧苄青霉素500 mg/L的筛选分化培养基上诱导分化，待抗性芽长到2～3 cm后，转入含Km 50 mg/L和Cb 500 mg/L的筛选生根培养基上进行筛选，在以上最佳遗传转化条件下，初步筛选到54株转化体，经PCR和RT-PCR检测获得25株转化烟草植株。
