The biggest figure is dicotyledon wild liane,the small families and single species genera have a larger quantity than the big ones,and the herbage and twinning-stem plants are in a dominant position.

其基本特点是：双子叶植物科属种较多，小型科和单种属占的比例较高，草本植物和缠绕型植物占优势。

The results indicated that the pattern of reserving broad-leaved tree in Chinese fir stand has a flora of 57 families, 102 generas and 138 species more than that of pure stand, which is dominated by dicotyledon that occupied 61.4%and 68.6%of total families numbers and total generas numbers, respectively.

双子叶植物在群落植物组成中占优势，分别占总科数和总属数的61.4％和68.6％。

The conserved regions of rRNA and tRNA genes exhibited higher sequence similarity among plant species. Five primer pairs were designed from the conserved regions distributing in psbA~trnK, psbB~psbH, rpl23~trnI, trnR-ACG~trnN-GUU and trnY-GUA~trnD-GUC, respectively to amplify sequences about 500~600 bp, 800~900 bp, 650~700 bp (350 bp, not legume species), 700~800 bp (400 bp in dicotyledon), and 500~600 bp.

经由上述比对分析后设计出5引子对，位於叶绿体基因体的位置分别为psbA~trnK、psbB~psbH、rpl23~trnI、trnR-ACG~trnN-GUU及trnY-GUA~ trnD-GUC，预期实际应用在其他物种上所能增幅之变异序列长度分别约为500~600 bp、800~900 bp、650~700 bp (豆科以外物种为350 bp)、700~800 bp (双子叶植物为400 bp)及500~600 bp。

This research used genetic engineering techniques to insert hsf8 gene to dicotyledon expression vector pCAMBIA3300 that contains the selection marker gene bar. And pCAMBIA 3300-HSF8 has been transfered into new soybean lines Hajiao5337 and Hajiao5489 by A grobacterium tumefaciens.

本文将热激转录因子8(hsf8)基因构建在植物表达载体pCAMBIA3300电以大豆子叶节作为受体，通过农杆菌介导法将hsf8基因导入品质性状优良的两个高产大豆新品系哈交5337和哈交5489中，最后获得转基因植株。

Vector pDLBRBNPT contained plant selective marker gene nptⅡ and vector pCDMAR-Hyg contained plant selective marker hygramycin phosphotransferase gene , they fitted to dicotyledon and monocotyledon transformation respectively.

载体pDLBRBNPT含有植物选择标记基因nptⅡ，适合双子叶植物转化；而载体pCDMAR-Hyg的植物选择标记潮霉素磷酸转移酶(Hygramycinphosphotransferase，Hyg)分离，主要用于单子叶植物转化。

The methods disclosed herein can be used with a variety of host cells, including for example, dicotyledonous and monocotyledonous plant cells.

这里所公开的方法可以与各种宿主细胞，包括例如双子叶和单子叶植物细胞一起使用。

An order of dicotyledonous plants.

双子叶植物的一个目。

Family of more or less advanced dicotyledonous trees and shrubs and herbs.

或多或少先进的双子叶乔木灌木和草本植物科。

Since the plasmid is capable of independent replication in host cells of many dicotyledonous plants, it has been used as a cloning vector in GNETIC ENGINEERING.

在许多双子叶植物中质粒在寄主细胞中是独立的复制单元，所以可以在基因工程中用作克隆载体。

Dicotyledonous plants retain a series of strands.

双子叶植物中保留着一系列的束。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
