我们报道了从植物病原菌尖孢镰刀菌中克隆的重复DNA序列Foret1的分离。该克隆与逆转录病毒Pol1基因具有高度的序列相似性。与蛋白酶、逆转录酶、核糖核酸酶H同源的序列按此顺序被发现。整个结构与‘吉普赛’类的LTR-逆转录转座子同源。它与广泛存在于不同生物体中的元素的相似性可能是由于它在最近的进化时间里水平传递的结果。
We report here the isolation of Foret1, a repeated DNA sequence cloned from the fungal plant pathogen Fusarium oxysporum. This clone exhibits a high degree of sequence similarity with the retroviral pol genes. Sequences homologous to protease, reverse transcriptase, ribonuclease H are found in that order. The overall structure is homologous to the 'gypsy' class of LTR-retrotransposons. Its similarity to elements present in widely different organisms may result from its horizontal transmission in recent evolutionary time.
