Abstract:
Colletotrichum gloeosporioides sensu lato has been associated with anthracnose in diverse commercial crops. It is now established that C. gloeosporioides sensu lato comprises 33 phylogenetic species and C. gloeosporioides sensu stricto is not a common pathogen of tropical fruits. In this study, we investigated the phylogenetic relationships of 85 Colletotrichum isolates associated with select tropical fruits and flowering plants from India. In the ApMat marker analysis, the 85 isolates clustered with 7 known Colletotrichum species (C. aotearoa, C. dianesei, C. endomangiferae, C. musae, C. siamense, C. theobromicola, Glomerella cingulata f. sp. camelliae) and six novel lineages. One of the novel lineages is described and illustrated in this paper as Colletotrichum communis sp. nov., while new-host pathogen associations for C. aotearoa, C. endomangiferae, C. dianesei and C. theobromicola are reported from India. Out of the 85 isolates analysed in this paper, 73 isolates clustered within the C. siamense species complex, indicating that C. siamense species complex, not C. gloeosporioides sensu stricto, is common on tropical fruits. In comparison with act, cal, gapdh, ITS and tub2 gene markers, we recommend the use of the ApMat marker for accurate identification of cryptic species within the C. siamense species complex. We believe that the ApMat marker, in combination with one or two similar ‘phylogenetically superior’ gene markers, is a better candidate for species-level classification of fungi that were traditionally identified as ‘Colletotrichum gloeosporioides’. © 2014, School of Science.
