The results were showed that embryogenic calli were induced from young leaves, which were cultured on MS medium supplemented with 2,4-D 2mg/L and KT 0.2mg/L. For the proliferation of embryogenic calli, the suitable culture medium was MS+BA 8mg/L +NAA 1mg/L. The development and maturation of somatic embryo could be much improved by using the medium of MS+ZT 2mg/L or BA 5mg/L +IAA 0.2mg/L. For the induction of secondary somatic embryo from integral somatic embryo, the suitable culture medium was MS+KT 0.1mg/L+NAA 0.01 mg/L or MS+ZT 0.1mg/L+NAA 0.01 mg/L, the proliferation frequency is 214%, 256% respectively. The cotyledonary generated from somatic embryos of Aesculus hippocastanum L.

本文就欧洲七叶树的组织培养和体细胞胚发生以及植株再生进行了系统研究，主要结果如下：以植物细胞具有全能性的理论为依据，以欧洲七叶树幼嫩叶片为外植体，进行体细胞胚胎发生研究，研究结果表明，诱导愈伤组织的适宜培养基是MS+2，4-D 2mg／L+KT0.2mg／L，MS+BA 8mg／L+NAA 1mg／L有利于胚性愈伤组织的诱导和增殖，添加ZT 2mg／L或BA 5mg／L和IAA 0.2mg／L的MS培养基有利于体细胞胚发育和成熟，体细胞胚可直接诱导次生胚发生，MS+KT 0.1mg／L+NAA 0.01 mg／L或MS+ZT 0.1mg／L+NAA 0.01 mg／L培养基诱导效果最好，增殖频率分别为214％、256％。

Otherwise, the high expression level of PmSERK1 was detected in the regenerated cotyledonary embryos.

另外，在再生的子叶胚中，PmSERK1的表达量也很高。

In the present study, different genotypes of provided soybeans were screened via the cotyledonary node regeneration system.

本研究的主要结论如下： 1、子叶节器官发生途径的再生频率在不同大豆基因型之间差异较大。

The embryos at cotyledonary stage were taken to grow on glyphosate- and haloxyfop-contained MS-2 medium for two weeks.

WOX3 specifies the cell fate at the margins of cotyledonary primordia and regulates the rate of cell division in the margins of meristem in Arabidopsis.

阿拉伯芥的PRS/WOX3基因参与子叶原基边缘细胞专一性的决定，及调控分生组织边缘细胞分裂的速度。

Two-dimensional electrophoresis (2-DE) was used to study the variation expression of proteins of cucumber cotyledonary nodes induced with PP333. The characteristics and functions of differentially expressed proteins were analyzed with MALDI-TOF-TOF/MS and Protein Data Bank.

应用双向凝胶电泳技术研究PP333处理后黄瓜离体子叶节培养物差异蛋白的表达，结合质谱分析和蛋白质数据库检索，确定所检出差异蛋白质的性质和功能。
