Transformation of cucumber plant expression vecor pbet and pbemt were transferred to cucumber and pcr positive transgenic plants was obtained 黄瓜遗传转化将上述结果中的植物表达载体pbet和pbemt转化黄瓜获得pcr阳性植株。
This paper reports hairy roots induced by agrobacterium rhizogenes and production of regenerative plants from hairy root cultures in maize 本文利用发根农杆菌遗传转化玉米，通过毛状根的诱导、毛状根的分化培养获得再生植株。
During the last twenty years , the technology of plant genetic transformation has experienced a great advance and vast application 植物遗传转化的研究和应用在近二十年中取得了巨大的发展，但是木本植物的遗传转化却远远落后于大田作物和其他草本植物。
The primary results of our experiment as list below : 1 . we established the agrobacterium - mediated transformation system used suspension embryogenic callus for infection 主要的实验结果如下： 1 、建立了保定苜蓿的农杆菌介导悬浮胚性愈伤遗传转化体系。
Rose plants could be regenerated by both organogenesis or somatic embryogenesis , but somatic embryogenesis was mainly used for the regeneration of transgenic rose plants 月季通过器官和体细胞胚发生途径都能再生植株，但遗传转化主要是利用体细胞胚发生途径。
In our experiments , we transformed the grifola frondos ( bacidiomycete ) trehalose synthase gene ( tsase ) into tobacco to make further study to verify the function of the gene 本研究利用担子菌灰树花海藻糖合酶基因( tsase )遗传转化烟草，以进一步验证该基因的功能。
Tissue culture of soybean ( glycine max l ) and stem mustard ( brassica juncea mao ) in vitro and genetic transformation of soybean by agrobacterium tumefaciens were studied in this experiment 本论文研究了大豆的离体再生和根癌农杆菌介导的遗传转化及榨菜的离体培养。
3 . the factors influencing the transformation efficiency for agrobacterium - mediated methods were mainly studied the pre - culture , the concentration of agrobacterium , the time of infection and the effect of as 影响遗传转化的因素主要探讨了预培养、菌液浓度和侵染时间、 as 。
Armed with modified antibacterial peptide ( spcema and mcema ) and plant defensin afp , transgenic plants with broad - spectrum and strong disease resistance may be obtained 以上三个单价和一个双价抗菌肽表达载体在植物中的遗传转化，有望获得对病源真菌有广谱抗性的转基因植株。
