查询词典 triangularis

To improve the efficiency of Oxalis triangularis purpurea breeding, this study is done by leaf explant. 0.5 mg/L 6-BA and 0.5 mg/L NAA are added to the culture based on the last study. KT and 2,4-D concentrations impact on Oxalis triangularis purpurea regeneration system by "one-step method" are further studied.

Study on Tissue Culture and Rapid Propagation of Oxalis triangularis

以三角紫叶酢浆草丛生芽和叶片为外植体，研究不同激素水平对三角紫叶酢浆草组织培养的影响，探讨三角紫叶酢浆草快速繁殖的最佳途径。

Producing PHAs,and then were orientationally inserted into a prokaryotic expression vector pBV220. By analyzing the bioactibity and function of their products, the biological function of phaA, phaB and phaC was confirmed. These have been done in our laboratory. To make better use of the three genes by plant bioreactor, two groups of different plant expression vectors that can be used to produce PHAs in different plants were constructed, and the transformation of PHA in Oxalis triangnlaris has been preliminarily reseached.The following is the main results:Three plant expression vectors pBI121-A,pBI121-B and ubquiting-C, which can be used to be transformed into Oxalis triangularis were respectively constructed by using the phaA, phaB and phaC.

菌株的亚克隆基因组片段中，分离出phaA、phaB和phaC三个基因片段，定向克隆至原核表达载体pBV220，通过对其生物活性与功能分析，确证了基因phaA、phaB和phaC的生物学功能；为了通过植物生物反应器对这三个基因进一步研究利用，本实验利用这三个基因构建了两组可用于不同植物生产PHA的真核表达载体，并对紫叶酢浆草进行PHA基因遗传转化的初步研究，获得主要结果如下：利用克隆的phaA、phaB、phaC三个基因分别构建了可用于转化紫叶酢浆草表达载体pBI121-A、pBI121-B、uBquiting-C；可用于玉米转化的种子特异性表达载体p7S-A、pBI121-S-B、uBquiting-C。

The distribution of Na(superscript +) in intracellular and extracellular spaces in leaves of arrowleaf saltbush subjected to salt stresses was investigated by using a scanning electron microscope facilitated with an Auger electron spectrometer.
