First report of rhizopus soft rot of sweet potato (Ipomoea batatas) caused by Rhizopus microsporus in Korea.

Abstract

In 2016, a soft rot diseased sweet potato was collected from a farmer's field in Haenam region, Jeonnam province, Korea Republic. Blackish sporangia along with fungal mycelia were observed at the surface of sweet potato roots. The fungus was isolated and identified as Rhizopus microsporus based on morphological, molecular and pathogenicity analyses. The obtained sequence was deposited in GenBank (accession No. KY606252). This is thought to be the first report of R. microsporus on sweet potato in Korea Republic.
