Organogenesis induction was induced in epicotyl segments of 2 weeks old seedlings of this cultivar.

采用2周苗龄的实生苗上胚轴进行器官诱导再生。

This research aimed to optimize the organogenesis of epicotyl segments and to efficiently obtain transgenic plants of 'Bingtang' sweet orange (Citrus sinensis L. Osb.), an elite citrus cultivar in China.

本研究的目的是对冰糖橙上胚轴再生芽的器官发生条件进行优化并且有效地获得转基因柑橘植株。

Seedling epicotyl segments of 'Xupu' sweet orange(Citrus sinensis L.Osb.)were used as explants to establish Agrobacterium-mediated transformation system with chit42 and phyB genes.

为改良柑桔品种，以普通溆浦甜橙实生苗上胚轴为外植体，建立了农杆菌介导的遗传转化体系，并把chit42基因和phyB基因导入其中。

The results showed that transformed buds could be obtained after the epicotyl segments were cultured on co-culture medium (MS+3mg/L BA) for 3 days and then on selective medium with 100 mg/L Kanamycin and 500 mg/L Cefotaxime for 2 weeks. The transformation efficency of Sweet orange with the chit42 and phyB genes reached 27.8% and 35.6%, respectively.

上胚轴经农杆菌工程菌液浸染后，在共培培养基(MS+3mg/LBA)上培养3d，然后分别转移到含有100mg/L Kan（卡那霉素，Kanamycin）和500mg/L Cef（头孢噻肟霉素，Cefotaxime）的选择培养基上培养14d后，上胚轴开始分化抗性芽，chit42基因和phyB基因的抗性芽再生率分别为27.8%和35.6%。

Distribution of new human beta-defensin genes clustered on chromosome 20 in functionally different segments of epididymis.

提示这一转录因子在人角膜上皮细胞中对HBD-2的上调的重要性。
