  • Methods : ( 1 ) the segregation of foreign target gene in the t1 by histochmical gus assays ; ( 2 ) identification of pure line from transgenic tomatoes ( tl ) through examining gus expression in pollens in conjunction with pcr analysis of marker gene ( npt ) ; ( 3 ) the transcript levels of leetrl or leetr2 in anti - sense transgenic plants ; ( 4 ) the phenotypes of the transgenic plants in tomato during whole life cycle under ethylene - treated and non - treated conditions
    本研究以反义乙烯受体leetr1 , leetr2基因番茄t _ 0代种子为实验材料,利用gus基因表达研究外源基因的遗传规律,并借助于pcr技术对目的和标记基因的鉴定获得转基因t _ 1代材料。利用gus基因在t1花粉中的表达鉴定获得转基因纯合植株。研究了转基因后代的生长发育模式、对外源乙烯敏感性,以及靶基因的表达特性,初步探明了它们在乙烯受体系统中的功能。
  • These results demonstrated that merely examining the segregation of reporter gene in pollens is a reliable method that could avoid the laborious testing process of the pure line from transformed plants ; ( 3 ) the transcript levels of leetrl and leetrl were checked by northern blotting analysis
    ( 3 )两个基因在反义植株里的表达都受到不同程度的抑制。在反义leetr1植株里, leetr1表达被抑制后, leetr2的表达也受到不同程度的抑制。同时,反义leetr2植株里也有相似的结果。
