我们在这里报告发现的一个家庭的转座因子,我们称之为Fot1元素,在真菌植物病原体尖孢镰刀菌。 第一个元件被鉴定为编码硝酸还原酶的基因中的插入。 它长1928 bp,具有44 bp反向末端重复序列,包含一个大的开放阅读框,侧翼为2 bp(TA)靶位点重复。 该元件与包括秀丽隐杆线虫Tc1在内的一类转座子具有显著的结构相似性,因此代表了真菌中一类新的转座元件。
We report here the discovery of a family of transposable elements, which we refer to as Fot1 elements, in the fungal plant pathogen Fusarium oxysporum. The first element was identified as an insertion in the gene encoding nitrate reductase. It is 1928 bp long, has 44 bp inverted terminal repeats, contains a large open reading frame and is flanked by a 2 bp (TA) target site duplication. This element shares significant structural similarities with a class of transposons that includes Tc1 from Caenorhabditis elegans and therefore represents a new class of transposable elements in fungi.
