Ribosomal DNA (rDNA) reportedly has multiple copies in the fungal genome. The internal transcribed spacer (ITS) region in rDNA is useful for investigating relationships between close taxonomic relatives. Thus, ITS has been widely used as a target gene in medical mycology for the detection of pathogenic fungi and identification of fungal species. However, the rDNA copy number in a genome of Trichophyton interdigitale, the pathogen causing dermatophytosis, currently remains unknown.

指间毛癣菌基因组中核糖体DNA拷贝数的变化

据报道，核糖体 DNA (rDNA) 在真菌基因组中有多个拷贝。rDNA 中的内部转录间隔区 (ITS) 区域可用于研究近亲分类关系之间的关系。因此，ITS已被广泛用作医学真菌学中的靶基因，用​​于病原真菌的检测和真菌物种的鉴定。然而，引起皮肤癣菌病的病原体叉指毛癣菌基因组中的 rDNA 拷贝数目前仍然未知。
