“…In addition to infecting coffee, C. siamense a wide host range, including on fruit of Persea americana, Carica papaya and Capsicum annuum , leaves of Hymenocallis americana , Hevea brasiliensis and Camellia sinensis , and seed of Dioscorea rotundata (Liu et al, ; Wang et al, ; Weir et al, ). It has been confirmed that C. siamense can infect more than 60 plant species worldwide (Ji et al, ).…”

Sterculia nobilis is an important tropical woody plant with high ornamental and economic value. At present, there are few reports of diseases on this plant. In August 2018, an unknown leaf spot disease was observed on S. nobilis in Nanning, China, affecting the inner leaves of the canopy and causing considerable defoliation. The pathogen was isolated, and pathogenicity tests carried out on detached leaves to verify Koch's postulates. Based on morphological observations and polygenic analyses, the pathogen causing leaf spots on S. nobilis was identified as Colletotrichum siamense.

“…The pathogen responsible for leaf spot on S. tonkinensis in China has been identified in this study as C. siamense based on morphological and molecular studies. Colletotrichum siamense can infect more than 60 species of plants worldwide (Ji et al 2019), but there have been no previous reports of the pathogen on S. tonkinensis. In China, various diseases caused by C. siamense can infect other hosts include Sterculia nobilis (Zhang et al 2020a, b), Sterculia lanceolata (Zhang et al 2020a, b), Hevea brasiliensis (rubber tree) (Cao et al 2019), Mallotus oblongifolius (Partridge tea) (Liu et al 2018), Macadamia sp.…”

A leaf spot, found on Sophora tonkinensis in Hechi city, Guangxi province, China was identified as Colletotrichum siamense based on morphological and molecular phylogenetic analysis of the internal transcribed spacer (ITS) of ribosomal DNA, β-tublin (TUB2), the translation elongation factor 1-alpha (TEF1-α), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), actin (ACT), chitin synthase 1 (CHS-1), calmodulin (CAL) and glutamine synthetase (GS) genes. Koch's postulates were satisfied by successful reisolation of C. siamense only from plants inoculated with the pathogen. This is the first report of leaf spot caused by C. siamense on Sophora tonkinensis.
