Taxonomical Study of Noteworthy Species of Botryosphaeria in Japan

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-a, b-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.

Toward a Natural Classification of Botryosphaeriaceae: A Study of the Type Specimens of Botryosphaeria sensu lato

“…Based on the phylogenetic analysis of 28S rDNA sequences, Crous et al (2006) recognized ten clades in the Botryosphaeriaceae , and noted that the morphology of the conidial morphs was more informative in generic circumscription. Thus far, Botryosphaeria sensu lato was reported being highly polyphyletic with only eight species being treated in Botryosphaeria sensu stricto ( Crous et al, 2006 ; Phillips et al, 2008 , 2013 ; Slippers et al, 2014 ; Ariyawansa et al, 2016 ; Zhou et al, 2016 , 2017 ; Hattori et al, 2021 ; Zhang et al, 2021 ).…”

“…В последние годы была проведена ревизия рода Botryosphaeria и описано более десяти новых видов (Liu et al, 2012;Slippers et al, 2014;Zhou et al, 2016Zhou et al, , 2017Li et al, 2018;Chu et al, 2021;Hattori et al, 2021). Использование только морфологических характеристик для точной идентификации видов Botryosphaeria недостаточно, поскольку признаки могут перекрываться с другими видами Botryosphaeriaceae (Marsberg et al, 2017).…”

The first detection of Botryosphaeria sinensis on white lupine

“…Для точной идентификации штаммов Botryosphaeria spp. молекулярными методами применяют филогенетический анализ последовательностей нескольких участков генома гриба (Crous et al, 2006;Zhou et al, 2017;Hattori et al, 2021).…”
