Reaction conditions are studied, and the result shows that it is better to adopt mercuric oxide or mercuric fluoride as fluorination catalyst with reaction temperature -20~-10℃.

结果表明，采用氧化汞或氟化汞作氟化催化剂、氟化氢作溶剂较好，适宜的反应温度为－20~-10℃，较长的反应时间(48 h)和增加氟化氢和催化剂的量有利于氟化。2-氯－5-三氯甲基吡啶的转化率和选择率均可达到97%以上。

The multiple alignment and phylogenetic analysis demonstrated that each genewas a member of a multigene family. 3. The function of 3GT gene was confirmed by Agrobacterium-mediatedtransformation of arabidopsis thaliana. Arabidopsis thaliana was transformed by floral dip method with AgrobacteriumGV3101 carrying expression vector pG3GT. Four transformants were selected for theirgrowth ability on 1/2MS medium containing 50mg/L kanamycin.

马铃薯野生种3GT基因的功能验证为了验证马铃薯野生种3GT基因的功能，构建带CaMV 35S启动子的表达载体pG3GT，转化农杆菌GV3101，用茵液浸泡花序法对拟南芥进行遗传转化，在含50mg／LKan的1／2MS培养基上筛选，得到4个抗性幼苗，转化率为0.13％，对移栽成活的3株进行PCR检测为阳性，Southern blot分析2株表现为阳性并为单拷贝整合。

The industrial application showed that the key process parameters, such as the regenerator dense phase temperature and the temperature under the first tray of the fractionator bottom, etc.
