根据GenBank上已发表的NDHB氨基酸序列，设计合成了一对简并引物，采用RT-PCR技术对绒毛白蜡NADH还原酶第二亚基基因进行扩增，将扩增的PCR产物与pMD18-T连接后转化至E。

Oneyear old poted Fraxinus velutina and Robinia pseudoacacia seedings were tested by neutral salt and mixed salt solutions.The dynamic changes of a,b and total contents of chlorophyll were studied and the correlation of chlorophyll with MDA and Pro was analysed.

用不同浓度的中性盐和碱性盐(NaCl、NaHCO3、Na2SO4、 Na2CO3)溶液处理1 a生刺槐和绒毛白蜡，研究了两树种叶片中叶绿素a、叶绿素b和总叶绿素含量的动态变化以及叶绿素和丙二醛、脯氨酸的相关性。

A novel cDNA encoding the second subunit of NADH dehydrogenase was cloned from Fraxinus velutina Torr by RT-PCR and designated as FvndhB.

采用RT-PCR 技术克隆了绒毛白蜡NADH还原酶第二亚基cDNA 序列。

EAB attacked ash species in the Section Fraxinus and Section Meliodes of Subgen. Fraxinus, such as F. americana, F. pennsylvanica var. subintegerrima, F. velutina, F. nigra, and F. mandshurica. Contrary to reports in the early literature, EAB was rarely found infesting native species F.

Effects of extragenous enzymes on the development of gut, digesta pH value, vili structure of small intestine, growth performance of piglets, effects of extragenous digestive enzymes and polysaccharide enzymes on endogenous enzymes activities were also determined.

试验研究了外源酶对仔猪消化道组织生长、食糜pH值、小肠绒毛形态结构及生长性能的影响及添加消化酶和聚糖酶对仔猪消化系统内源酶活（胃蛋白酶、胰蛋白酶、胰淀粉酶和粘膜二糖酶）的影响。

Objective To study the relationship of different kinds of digestive enzyme with villiform cell culture and chromosome preparation.

目的 探讨绒毛组织培养及染色体制备的理想方法。

Results The time of villiform cell culture was obviously related to the kinds of digestive enzyme, but not to the number of karyotypes. The villiform cells of 68 specimens (93.15%) were cultured successfully and 30 abnormal karyotypes were tested.

结果 经不同消化酶处理后，绒毛细胞培养时间具有显著相关性，但与核分裂相的数目无相关性。73例中，68例培养成功，成功率93.15%，检出异常核型30例。

A: This situation is more and more generally the first villous grow hair, and slowly blackened, the new black hair, large individual differences in the time.
