| 摘 要： | 以黄瓜无菌苗子叶切段为外植体,通过叶盘转化法与根瘤农杆菌进行共培养建立了黄瓜的遗传转化体系.比较了不同苗龄,不同侵染时间对黄瓜离体再生的影响,并做了潮霉素敏感性测试.结果表明:苗龄3～4 d的子叶,侵染时间为15min,潮霉素浓度为25 mg/L最适分化出抗性小苗.最终获得3株抗性植株,经过PCR和PT-PCR检测,初步确定均为阳性转化植株.

| Abstract: | In this experiment,we chose cotyledon segments of Cucumis sativus L.as explants,and transformation was mediated by Agrobacterium tumefaciens.We compared the effect of different seeding age,different infection time on cucumber in vitro regeneration,and made a test of hygromycin for screening.The results were as follows: seeding age were 3 or 4 day,infection time was 15 minutes,the concentration of hygromycin was 25 mg/L,could best obtain putative transgenic adventitious bud differentiation.Finally,we got thr... |
