Genetic transformation of chinese cabbage with a inducible potato pin gene and the bioassay for pieris rapae l . resistance 大白菜的马铃薯蛋白酶抑制剂基因转化及抗菜青虫性的鉴定
4 . individual transgenic plants containing the same construction exhibited a wide range of gus activity because of position effect . 5 由位置效应引起而非转基因拷贝数的不同导致同一基因转化的株系中基因表达水平有差异。
The achievement of transgenetic plants would provide a scientific basis and lay firm foundation for the transformation of hfl and hf2 gene into other ornamental flowers 转基因植株的获得，将为以后hf1 、 hf2基因转化其它名贵花卉作物提供科学依据，并打下良好的基础。
The recent advances about laser microbeam in plant transformation of exogenous gene , key techniques and applications are introduced . and the prospects is anticipated 摘要本文概述了近年来激光微束在植物外源基因转化上的最新进展，激光微束转化法的关键技术及应用。并对其今后的应用前景作了展望。
This thesis was aimed to study the cloning and expression of the luxs from bacillus thuringiensis and the effects of the ai - 2 signal molecular biosynthesis on plant disease resistance 本论文研究了苏云金芽孢杆菌( bacillusthuringiensis ， bt )中luxs基因的克隆表达及将该基因转化烟草后对抗病的影响。
The suitable concentration of hyg to screen for resistant shoots was 50 mg / l . the kind of antibiotics to inhibit the growth of agrobacterium eha105 was cef , of which concentration was 250 mg / l 以洋桔梗叶盘为外植体，通过根瘤农杆菌菌株eha105介导，用构建于质粒pcambia1301的npr1基因转化洋桔梗。
In the present study , an omanental flower sinningia speciosa was transformed with tmek2 and tmek2mut : , the wild type and mutant type of mapkk from tomato , by agrobacterium tumefaciens 本研究用野生型、突变型mapkk基因转化观赏花卉大岩桐，为进一步研究mapkk基因的功能奠定基础，也为花卉植物的转基因提供实验系统。
We reviewed the advances on the rice transgenic study including applications of transformation , applications of transgenic technology , and the inheritance and expression of exogenous genes in transgenic off - springs 综述了水稻基因转化的方法、转基因技术在水稻上的应用及外源基因在转基因后代中的遗传表达的研究进展。
Based on this , a reasonable hypothesis was put forward that primary genetic law in ion beam - transformation was decided by random integration of multiple genes controlling the same trait on receipt chromosomes and the mendel heredity of these genes with located chromosomes 实验结果表明，通过离子束介导外源全dna转化可以把供体中控制某一复杂性状的多个基因转化到受体细胞，并协调表达。
