Endangered Uyghur Medicinal Plant Ferula Identification through the Second Internal Transcribed Spacer.

ABSTRACT: The medicinal plant Ferula has been widely used in Asian medicine, especially in Uyghur medicine in Xinjiang, China. Given that various substitutes and closely related species have similar morphological characteristics, Ferula is difficult to distinguish based on morphology alone, thereby causing confusion and threatening the safe use of Ferula. In this study, internal transcribed spacer 2 (ITS2) sequences were analyzed and assessed for the accurate identification of two salable Ferula species (Ferula sinkiangensis and Ferula fukangensis) and eight substitutes or closely related species. Results showed that the sequence length of ITS2 ranged from 451 bp to 45 bp, whereas guanine and cytosine contents (GC) were from 53.6% to 56.2%. A total of 77 variation sites were detected, including 63 b
