简介：细胞色素P450基因的新奇完整的长度被孤立在杀虫药剂抵抗(命名CYP6CX1v1)并且易受影响(命名CYP6CX1v2)Bemisiatabaci，作为B遗传因子型被识别，福建，中国(Sj)。CYP6CX1(1940bp包含了1557bp开的读框架)对CYP6成员普通的包括的保存领域在carboxyl附近的helix-K，氧绑定主题AGLDPV和保存顺序PEKFNP的通常认为的曲流绑定顺序ETLR和PERF例如heme有约束力的主题PFGEGPRFCIA，结束。有在R和SB之间的氨基酸残余的四不同代替。tabaci(Thr300翼，Thr354Pro，Arg486His和Ile503Thr)，在哪个之中替换Ile503Thr位于底层识别地点区域。CYP6CX1v1的mRNA抄写水平象CYP6CX1v2的一样高是2.38褶层。结果显示了从B遗传因子型B的CYP6CX1。在Sj的tabaci是CYP6成员之一，并且提高了CYP6CX1表示和氨基酸残余的代用品可能在域B涉及抵抗机制。tabaci。
