First report of brown rhizome rot of ginger (Zingiber officinale) caused by Musidium stromaticum

Brown lesions observed on ginger rhizomes in Kochi Prefecture, Japan, appeared to be symptoms of a previously unknown disease. A filamentous fungus was isolated at high frequency from the lesions and identified as Musidium stromaticum based on its morphology and molecular analyses of ITS, LSU, TEF1-...

Description
Summary:Brown lesions observed on ginger rhizomes in Kochi Prefecture, Japan, appeared to be symptoms of a previously unknown disease. A filamentous fungus was isolated at high frequency from the lesions and identified as Musidium stromaticum based on its morphology and molecular analyses of ITS, LSU, TEF1-α , and RPB2 . Rhizomes developed the same symptoms after inoculation with the fungus. We propose the name “brown rhizome rot” to describe this new disease of ginger. This study is the first report of M. stromaticum as a plant pathogen of ginger.
