Multiple mycoviruses identified in Pestalotiopsis spp. from Chinese bayberry.

ABSTRACT:

Background

Chinese bayberry (Myrica rubra) is a subtropical fruit crop widely grown in southern China. Twig dieback is a disease of Chinese bayberry caused by Pestalotiopsis spp. and results in great economic losses to Chinese bayberry production. A virus survey was conducted in the population of Pestalotiopsis spp. infecting M. rubra in China. We explored the viral diversity in Pestalotiopsis spp., which may provide resources for further development as biocontrol agents of twig dieback.

Methods

Strains of Pestalotiopsis spp. were isolated from diseased twigs of M. rubra, and cultured on potato dextrose agar for RNA extraction. The total RNA of each strain was extracted, mixed, and used for RNA sequencing. The resulting sequences were deduplicated, annotated, and then used f
