  cotyledon regeneration
The effect of the embryonic axis, BA, and TDZ on cotyledon regeneration was investigated in detail.
      
The addition of auxin in the cotyledon regeneration assayreduces the differences.
      


The morphogenesis of explants cultured in vitro was affected by three different antibiotics, i.e. Carbenicillin, Claforan, and Keflodin. All of them showed an unfavorable effect on microspore embryogenesis in isolated microspore culture of Brassica napus cv. Topaz. For Carbenicillin, within the range of 0-500mg/L, the higher the concentration, the less the embryos were produced. The best concentration of Carbenicillin seemed to be 50mg/L for inhibiting bacteria growth and achieving favourable production of embryos....

The morphogenesis of explants cultured in vitro was affected by three different antibiotics, i.e. Carbenicillin, Claforan, and Keflodin. All of them showed an unfavorable effect on microspore embryogenesis in isolated microspore culture of Brassica napus cv. Topaz. For Carbenicillin, within the range of 0-500mg/L, the higher the concentration, the less the embryos were produced. The best concentration of Carbenicillin seemed to be 50mg/L for inhibiting bacteria growth and achieving favourable production of embryos. Carbenicillin also had some stimulative effects on callus formation of pepper cotyledon explants, and on rooting of regenerated plants resulting in shorter and thicker roots or even roots with tumors.

抗生素羧苄青霉素(Carbenicillin),头孢霉素Ⅱ(Keflodin)和Claforan影响甘蓝型油菜(Brassica napus L.)游离小孢子培养胚胎发生,其浓度越高,影响越大.羧苄青霉素促进辣椒(Capsicum annuum L.)子叶外植体愈伤组织发生,同时,还影响油菜小孢子胚再生植株及辣椒子叶再生株的生根,产生粗短根甚或发育为瘤状物.

An efficent and high regeneration frequency system was established for hypocotyl of cauliflower, in which the regeneration frequency up to 100% . The main effect factors to be studied are BA、NAA、AgNO3 etc. The best medium is MS + BA4.5mg/L+ NAA0. 10mg/L + AgNO35.0-10.0mg/L.

本文研究了BA、NAA、AgNO_3、子叶龄、培养密度以及Km对花椰菜子叶再生系统的影响,建立了一个高频再生系统,使再生频率达100%,其最佳各成分的配比是:MS+BA4.5mg/L+NAA0.1mg/L+AgNO_35.0~10.0mg/L.

The cotyledons,cotyledon petioles and leaves of Brassica chinensis cv.Aijiaohuang and Suzhouqin were used as transformation recipients.The regenerated plants were obtained on the modified MS medium with growth regulators.The presence of 2-20 mg/L AgNO 3 on the shoot induction medium markedly enhanced shoot regeneration frequencies from cotyledons.The percentage of shoot regeneration and the number of shoots per cotyledon were increased on the medium...

The cotyledons,cotyledon petioles and leaves of Brassica chinensis cv.Aijiaohuang and Suzhouqin were used as transformation recipients.The regenerated plants were obtained on the modified MS medium with growth regulators.The presence of 2-20 mg/L AgNO 3 on the shoot induction medium markedly enhanced shoot regeneration frequencies from cotyledons.The percentage of shoot regeneration and the number of shoots per cotyledon were increased on the medium supplemented with 0 1 mg/L NAA and 1 to 2 mg/L CPPU. By means of Agrobacterium mediated transformation,plantlets resistant to kanamycin were obtained from cotyledons of Brassica chinensis. The Agrobacterium tumefaciens strain LBA4404 harbouring mini Ti plasmid pRCL27 carrying the CpTI gene and NPTII gene was used for transformation.Carbenicillin could increase percent shoot regeneration, while cefotaxime reduced shoot regeneration.The test also showed that shoot regeneration from cotyledons was inhibited by kanamycin.All of shoots turned white on the medium with 10 mg/L kanamycin.Therefore,10 mg/L kanamycin was applied to the selection of transformed shoots.

以青菜地方品种矮脚黄、苏州青的子叶、子叶柄、真叶为外植体,在改良MS培养基上离体培养获得再生植株。在不定芽诱导培养基中添加2~20mg/LAgNO3可显著提高子叶不定芽诱导频率;添加0.1mg/LNAA和1~2mg/LCPPU既可提高不定芽诱导频率,又可获得较多数量的不定芽。用含CpTI基因和NPTII基因的农杆菌感染子叶,获得了具有卡那霉素抗性的再生植株。培养基中添加羧苄青霉素促进子叶再生不定芽,头孢霉素和卡那霉素则抑制子叶再生。卡那霉素敏感性测定结果表明,当培养基中含卡那霉素10mg/L时,非转化再生植株100%白化
