Resumo: |
In the current study the Colletotrichum species isolated from mango in Pernambuco state in Brazil are described, as well as their distribution in different plant tissues. The Colletotrichum isolates are characterized through cultural, morphological, patogenicty and vivirulence data, and from phylogenetic analyses based on a partial sequence of the gene glyceraldehyde-3-phosphate dehydrogenase (GPDH). There was significant difference in isolament frequency among sites and plant tissues. In the locality of Aldeia (site III) it was observed the highest isolation frequency. The old limb was the part of plant most colonized in a higher number of sites. Colletotrichum asianum, C. fructicola, C. cliviae, C. boninense and two unidentified species were found as endophyte in mango, and C. asianum was prevalent over the other. All isolates were pathogenic in mango fruits. The phylogenetic analysis revealed groupings that were congruent with morphological characters, but did not group isolates according to phenotypic characters. There was no distribution pattern of species in different areas, neither in plant tissues. |
