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 . 關于花色結構基因查爾酮異構酶chi ( chalconeisomerase )基因對花色改變的直接報道很少,因此,本論文選用了chi基因為目的基因,以純深紅色和純白色矮牽牛( petuniahybidavilm . )為材料,研究了chi基因的共抑制和反義抑制以及表達產物增加對花色改良的作用,并在花色改變植株中首次觀察到花器官變異。
