The root rot complex caused by various pathogens is a main constraint in faba bean production. In April 2021, a severe disease of faba bean with symptoms of black necrosis on roots occurred in experimental fields at the Linxia Institute of Agricultural Sciences, Gansu Province, China. This study aimed to identify the pathogen and evaluate the resistance of faba bean cultivars. The pathogen was isolated from infected soils, and five representative isolates were identified as <i>Berkeleyomyces rouxiae</i> based on morphological characteristics, pathogenicity, and molecular phylogenetic analyses. A host range test showed that chickpea, common bean, cowpea, mung bean, rice bean, lentil, and hyacinth bean wFrontiers in plant science989517https://www.ebi.ac.uk/biostudies/studies/S-EPMC9774499biostudies-literature<i>Berkeleyomyces rouxiae</i> is a causal agent of root rot complex on faba bean (<i>Vicia faba L</i>.).PMC9774499Zhu ZShao YGuo YLong JSun SDuan CWu Wfalse<i>Berkeleyomyces rouxiae</i> is a causal agent of root rot complex on faba bean (<i>Vicia faba L</i>.).Faba bean (<i>Vicia faba</i> L.) is an important food and feed legume crop in the world.
