查询词典 betaine

As an important plant osmotic regulators, glycine betaine in plants, under the osmotic stress, can be accumulated in order to give the plants high salt-tolerance by reducing osmotic pressure and maintaining proteinic structure in cell.

甘氨酸甜菜碱是一种重要的调渗物质，在盐胁迫下有些植物能通过体内甘氨酸甜菜碱的积累保护细胞内蛋白质的结构和功能，降低细胞水势，从而来增加自身的耐盐能力。

Salicornia europaea is a dicot halophyte,which could grow in marsh with salinities greater than 3.5%and the major osmotica in its fleshy stems was Na~+ and g lycine betaine.

The open reading frame of Spinacia oleracea Betaine Aldehyde Dehydrogenase was retrieved from Spinacia oleracea and inserted into the Agrobacterium tumefaciens binary vector pBin438, which was driven by CaMV35S promoter, and produced the new binary vector pBSB. A. tumefaciens LBA4404 carrying this plasmid was used in genetic transformation of plants. Forty-five primary transgenic plants were detected by PCR and verified by the Southern blotting from 65 regenerated plants, of which 27 transgenic plants had only one copy of T-DNA.

摘 要：分离出菠菜甜菜碱醛脱氢酶基因构建成由CaMV35S驱动的双元植物表达载体pBSB，农杆菌菌株LBA4404携带该载体转化棉花，获得转基因棉花植株。65株转基因植株经过PCR筛选、Southern blotting分析证明有45株为成功的转化株，外源基因已经被整合到棉花的染色体组中，并以单拷贝插入居多。

Using TAV CP cDNA clones as templates, the reaction conditions such as Mg(superscript 2+ dNTPs, betaine and primers concentrations optimized and the sensitivities of LAMP and RT-PCR were compared in detecting TAV.

设计能识别TAV CP序列6个特定区域的4种LAMP特异引物，对MgCl2、dNTPs、甜菜碱等LAMP反应条件进行优化，利用新建的LAMP法检测TAV，比较LAMP和RT-PCR2种不同方法的检测灵敏度。

The different foaming performance of sodium laureth sulfate, cocamidopropyl betaine and their compounds under different active concentrations, water hardnesses and temperatures were investigated. The results show that the foaming performance of SLES doesn't change under different water hardness, but that of CAB changes with different concentration, and the compounds of SLES and CAB have much better foaming performance and synergetic effect under different conditions.

通过实验主要考察了在不同活性物浓度，不同水硬度条件和不同体系温度下，SLES、CAB和它们的复合物的泡沫性能，结果表明，SLES的泡沫性能受硬水影响不大，CAB的泡沫性能随浓度的变化而有所不同，SLES和CAB的复合物有更优秀的泡沫性能，表现出良好的协同增效性。
