虾池微藻定向培育及其对养殖环境因子的影响 - The result worked out here will provide strong scientific foundation and effective research approach when it comes to the research of wood quality and it ' s forming mechanism , wood transgene and directive breeding
这一结果将为木材性质研究、木材性质形成机理、树木优质种质资源培育、树木转基因工程、定向培育材质改良的树木新品种提供强有力的科学依据及研究方法。 - Gene engineering technology is more superior than the cross breeding and directive breeding technology with its short cycle , low cost and high benefit . though traditional breeding technology has been used for a long time . now the direct reports for the changes of the flower color by the chi ( chalcone isomerase ) gene are a few what we known .
关于花色结构基因查尔酮异构酶chi ( chalconeisomerase )基因对花色改变的直接报道很少，因此，本论文选用了chi基因为目的基因，以纯深红色和纯白色矮牵牛( petuniahybidavilm . )为材料，研究了chi基因的共抑制和反义抑制以及表达产物增加对花色改良的作用，并在花色改变植株中首次观察到花器官变异。
