Genetic diversity analysis of lychnis mottle virus and first identification of Angelica sinensis infection.

ABSTRACT: Gansu Province is a district renowned for the cultivation of Angelica sinensis (Oliv.) Diels, accounting for greater than 90% of China's total annual production. However, virus infection has caused a reduction in A. sinensis yield. Here, we collected suspected virus-infected A. sinensis leaf samples from Gansu Province's A. sinensis cultivation area. For the first time, using small RNA deep sequencing and RT-PCR, lychnis mottle virus (LycMoV) was found to naturally infect A. sinensis. The coat protein (cp) gene of the Gansu A. sinensis LycMoV isolate was obtained through cloning, where its nucleotide and amino acid identity was highest while having the closest affinity to the China Pearl (i.e., Prunus persica) isolate.
