共抑制 meaning in Chinese

cosupression

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。
