Taxonomical Study of Noteworthy Species of Botryosphaeria in Japan

Mycobiology. 2021 Mar 23;49(2):122-132. doi: 10.1080/12298093.2021.1895486. eCollection 2021.

Abstract

The reexamination of the fungal genus Botryosphaeria on 12 plant species of 10 families was carried out based on molecular phylogenetic analyses using the regions of translation elongation factor 1-α, β-tubulin, DNA-directed RNA polymerase II subunit, and internal transcribed spacer region of rDNA and morphological characteristics. Japanese isolates were divided into five clades and include Botryosphaeria dothidea, B. qingyuanensis, B. sinensis, and Botryosphaeria spp. Two species, B. qingyuanensis and B. sinensis have been newly added to the Japanese mycoflora, but their host plants are not specified. Botryosphaeria tenuispora isolated from Leucothoe fontanesiana and insect galls on fruits of Aucuba japonica has been proposed as a new species.

Keywords: Botryosphaeriaceae; new species; phylogeny; plant pathogen; systematics.
