Important Disease

Strawberry anthracnose caused by Colletotrichum species is an important disease that may cause significant economic losses. Based on multilocus sequence analyses and morphological characteristics, 64 isolates from strawberry anthracnose samples collected from nine Chinese provinces and municipalities were identified as three species: Colletotrichum fructicola (29 isolates), Colletotrichum siamense (23 isolates), and Colletotrichum nymphaeae (12 isolates). Isolates of C. siamense showed strong aggressiveness to fruit and leaves. Isolates of C. fructicola showed strong aggressiveness to crowns. Isolates of C. nymphaeae were weakly or not pathogenic to fruit, leaves, or crowns. Sensitivity to carbendazim was determined for a total of 75 isolates, including 11 previously preserved. Two isolates of C. siamense were highly resistant (HR) and 21 were moderately resistant (MR). Nine isolates of C. fructicola were sensitive (S), 24 were HR, and four were MR. All 15 isolates of C. nymphaeae were insensitive, and their mycelial growth was not completely inhibited on potato dextrose agar amended with 500 μg/ml carbendazim. Beta-tubulin (TUB2) of representative isolates was amplified and sequenced, revealing a glutamic acid substituted by alanine at codon 198 in HR isolates of C. siamense and C. fructicola. MR isolates of C. siamense and C. fructicola had a point mutation at codon 200, causing a replacement of phenylalanine acid by tyrosine. No point mutation was detected at codons 50, 167, 198, 200, or 240 in TUB2 of C. nymphaeae insensitive isolates. Overall, this study revealed that C. fructicola was the dominant species causing anthracnose on strawberry and could improve the understanding of the management of fungicide resistance in Colletotrichum species on strawberry in China.

Identification And Characterization

Mango (Mangifera indica) is widely grown across southern China, especially in the provinces of Guangxi, Hainan, Yunnan, Sichuan, and Taiwan. Guangxi itself has over 86,667 ha of mango production. The purpose of this study was to identify Colletotrichum species associated with mango in different parts of Guangxi and examine their pathogenicity on leaves and fruits of mango in vitro. Diseased leaves were collected from 25 mango orchards in different areas of Guangxi province. Sixty-five isolates were obtained from mango leaves with anthracnose symptoms, and these were further characterized based on morphology and DNA sequencing. Twenty-nine isolates from different areas were selected for sequencing and analyses of the internal transcribed spacer region, glyceraldehyde-3-phosphate dehydrogenase, partial actin, β-tubulin, and chitin synthase genomic regions. The most common fungal isolates were these three species: Colletotrichum asianum, C. fructicola, and C. siamense. C. asianum was the most common and widely distributed in Guangxi (51.7%), followed by C. fructicola (37.9%) and C. siamense (10.2%), both found in Tiandong, Tianyang, and Wuming counties. There was no evidence of geographical specialization of the different species. Pathogenicity assays showed that all isolates were pathogenic to mango leaves and fruit (cultivar Tainong). No relationship was found between origin of isolates and their virulence. This is the first description of C. asianum, C. fructicola, and C. siamense as causal agents of mango leaf anthracnose from Guangxi province, China.
