摘要(Abstract)：

【目的】克隆Ty3-gypsy类反转录转座子反转录酶(RT)序列并分析其特性,为火龙果遗传变异和进化研究提供新的信息。【方法】根据Ty3-gypsy类反转录转座子RT保守区设计简并引物,从红肉和白肉火龙果及其突变体中扩增出430 bp左右的目标片段,回收、克隆、测序获得RT序列,并进行生物信息学分析;采用RT-PCR检测其转录活性。【结果】共获得82条RT序列,其中有55条序列发生终止密码子突变,5条序列发生移码突变;经RT序列对比,火龙果与水稻、拟南芥有较高的同源性;3条RT序列具有转录活性。【结论】火龙果Ty3-gypsy类反转录转座子RT序列具有高度异质性,部分序列具有转录活性,与其他物种存在反转录转座子的横向传递。
