“…The endoconidia were hyaline, cylindrical in shape, and produced from phialides, which measured 10.49-25.10 mm × 4.41-6.10 mm in size, and the phialide were measured 5.8-8.2 mm × 112.3-226.7 mm in size (Figures 2B, E). The colony characteristics, chlamydospores, and endoconidia size of the isolates were similar to those of B. rouxiae (Nakane et al, 2019;Le et al, 2022).…”

“…In this study, we identified the agent causing black root rot of faba beans in experimental field plots in Gansu Province, China. Combining morphological, pathogenic, and molecular characteristics, the faba bean isolates were identified as B. rouxiae (Nakane et al, 2019;Le et al, 2022). Based on molecular phylogenetic analysis, Nel et al (2018) classified the pathogens causing black root rot from Ipomoea batatas and P. sativum as B. rouxiae (Nel et al, 2018).…”

New hosts of B. rouxiae including Cannabis sativa (Rahnama et al, 2022), Cucumis melo (Wang et al, 2019), Gossypium hirsutum (Le et al, 2022), and Lactuca sativa (Nakane et al, 2019) were found or confirmed since 2018. In this study, our results showed that B. rouxiae isolate LXBR1 from faba bean was pathogenic to chickpea, common bean, cowpea, hyacinth bean, lentil, mung bean, and rice bean, and infective to adzuki bean, pea, and soybean, whereas it could not infect wheat and maize.…”

The phylogenetic trees for tandem sequences of ITS, LSU, MCM7, 60S and a phylogenetic tree for MCM7 were constructed using the Maximum likelihood method and the Tamura-Nei distance model in MEGA 11 with 1000 bootstrap repeats (Kumar et al, 2016).…”

“…Thielaviopsis basicola is a cosmopolitan soilborne plant pathogen that attacks more than 230 plant species and causes the disease known as black root rot, and the number of new hosts is increasing ( Pereg, 2013 ; Nakane et al., 2019 ; Le et al., 2022 ; Rahnama et al., 2022 ). The disease is characterized by black necrosis on various parts of the host roots, which leads to stunting, reduced vigor, wilt, and yield loss ( Noshad et al., 2006 ; Coumans et al., 2011 ).…”

Faba bean (Vicia faba L.) is an important food and feed legume crop in the world. 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 Berkeleyomyces rouxiae 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 were susceptible hosts of the faba bean isolate, whereas adzuki bean, pea, and soybean were non-susceptible hosts, and maize and wheat were non-hosts. Identification of resistance among 36 faba bean cultivars was carried out, and six cultivars were found to be moderately resistant to B. rouxiae. In this study, we first reported black root rot on faba bean caused by B. rouxiae, confirmed and expanded the host range of B. rouxiae, and identified resistant faba bean cultivars.

Black root rot (BRR) is a major seedling disease of cotton in Australia. The disease is caused by Berkeleyomyces rouxiae (formerly known as Thielaviopsis basicola), which is morphological identical to B. basicola. In this diagnostic guide, we aim to share current work and understanding of the B. rouxiae in cotton in Australia. This guide includes a comprehensive signs and symptoms to allow correct identification of the disease in the field. Methods and tricks to isolate and purify the pathogen from soil and diseased cotton were also discussed. Additionally, available molecular approaches for accurate identification of B. rouxiae were summarized. Last but not least, methods to preserve and assess pathogenicity of B. rouxiae on cotton were also presented.
