“…The present study revealed high Colletotrichum species diversity associated with mango from the six major mango-grown areas in China. The Colletotrichum isolates examined here also showed high diversity, which may correlate with the diversity of environmental conditions such as temperature and rainfall 26 and the sample collection time and isolate source. Colletotrichum asianum , C. fructicola and C. siamense were found to be the major species associated with mango anthracnose in China.…”

Mango (Mangifera indica L.) is an economically significant fruit crop in provinces of southern China including Hainan, Yunnan, Sichuan, Guizhou, Guangdong and Fujian. The objective of this study was to examine the diversity of Colletotrichum species infecting mango cultivars in major growing areas in China, using morphological and molecular techniques together with pathogenicity tests on detached leaves and fruits. Over 200 Colletotrichum isolates were obtained across all mango orchards investigated, and 128 of them were selected for sequencing and analyses of actin (ACT), chitin synthase (CHS-1), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), the internal transcribed spacer (ITS) region, β-tubulin (TUB2) genomic regions. Our results showed that the most common fungal isolates associated with mango in southern China involved 13 species: Colletotrichum asianum, C. cliviicola, C. cordylinicola, C. endophytica, C. fructicola, C. gigasporum, C. gloeosporioides, C. karstii, C. liaoningense, C. musae, C. scovillei, C. siamense and C. tropicale. The dominant species were C. asianum and C. siamense each accounting for 30%, and C. fructicola for 25%. Only C. asianum, C. fructicola, C. scovillei and C. siamense have previously been reported on mango, while the other nine Colletotrichum species listed above were first reports associated with mango in China. From this study, five Colletotrichum species, namely C. cordylinicola, C. endophytica, C. gigasporum, C. liaoningense and C. musae were the first report on mango worldwide. Pathogenicity tests revealed that all 13 species caused symptoms on artificially wounded mango fruit and leaves (cv. Tainong). There was no obvious relationship between aggressiveness and the geographic origin of the isolates. These findings will help in mango disease management and future disease resistance breeding.

“…Other publications have shown behavioural differences within and among populations of Colletotrichum spp. in response to environmental conditions (Estrada et al, 2000;Leandro et al, 2003;Moral et al, 2012;Miles et al, 2013;Wang et al, 2015), thus highlighting their pheno- species represented only 1.4% of the 280 isolates collected from cashew plants in Brazil (Veloso et al, 2018). This species was revealed as aggressive as C. chrysophilum, C. fragariae, and C. tropicale on wounded cashew leaves, while C. siamense and C. fructicola induced the largest and the smallest lesions, respectively.…”

“…A series of experiments was performed using 21 representative isolates of seven Colletotrichum species (C. chrysophilum, C. fragariae, C. fructicola, C. gloeosporioides, C. queenslandicum, C. siamense, and C. tropicale) associated with anthracnose on cultivated and noncultivated cashew plants in Brazil (Table 1).

Native to South America, Anacardium occidentale (Anacardiaceae), popularly known as the cashew tree, is a plant species widely distributed throughout the Brazilian territory. It grows as a crop or in non-agricultural habitats along with noncultivated Anacardium species, such as A. corymbosum, A. humile, A. nanum, and A. othonianum (Barros et al., 2002; Agostini-Costa et al., 2006). The fully ripened cashew fruit consists of a soft yellow and/or reddish edible hypocarp (5-11 cm in length), known as a "cashew apple", with

“…It is a ubiquitous species, commonly associated with anthracnose on fruits and leaves, but also a prevalent endophyte (Farr & Rossman, 2020). Reports of C. siamense causing anthracnose and leaf necrosis in Brazil include the fruit trees Annona squamosa and A. muricata , and cashew trees (Costa et al., 2019; Veloso, Câmara, Lima, Michereff, & Doyle, 2018). Colletotrichum siamense was also reported as a common leaf endophyte of mango in the north‐eastern region of the country (Vieira, Michereff, Morais, Hyde, & Câmara, 2014).…”

Cenostigma tocantinum, a new host of Colletotrichum siamense

Cenostigma tocantinum Ducke (Fabaceae), popularly known as "pau-pretinho," is a tropical tree native to the Amazon region, also found in the biomes Cerrado and Mata Atlantica in Brazil. This tree species is commonly found in different Amazonian landscapes, including primary forests, highland and seasonally flooded forests (Warwick & Lewis, 2009). In the northern region of Brazil, Ce. tocantinum is used for reforestation of degraded areas and urban afforestation projects, due to its rapid growth, straight trunk and leafy crown (Garcia, De Moraes, & De Lima, 2008). The wood of Ce. tocantinum is commonly used as raw material in the construction sector (Warwick & Lewis, 2009). A foliar disease of Ce. tocantinum was recently observed in a forest nursery and surrounding areas inside the main campus of the Federal University of Amazonas, Brazil. Disease symptoms included irregular brown spots surrounded by chlorotic areas. The production of orange spore masses in acervuli on the leaves suggested that the causative agent was a fungal pathogen. The aim of this work was to investigate the aetiology of this disease.
