Colonies on PDA apricot coloured from the aerial view, reverse orange, aerial mycelium sparse, growth rate at 25 °C 5.7–6.3 mm.dia(average 5.9 ± 0.3 mm. dia-1). Conidiogenous cells hyaline, smooth-walled, cylindrical to ampulliform, often extending to form a new conidiogenous locus (percurrent proliferation).

Conidia one-celled, hyaline, smooth-walled, cylindrical with rounded ends, contents appearing granular. Conidia on PDA 9.6–13.8 × 3.4–4.4 μm (av. 10.7 ± 1.1 × 3.8 ± 0.3 μm).

No. of bitstreams: 1 Willie Anderson dos Santos Vieira.pdf: 939430 bytes, checksum: b3f788b1dafa1b55d7a74abaf64a9110 (MD5) Previous issue date: 2012-02-28 Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq 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. No presente estudo são relatadas as espécies de isolados de Colletotrichum endofíticos associados a mangueiras no Estado de Pernambuco/Brasil, e sua distribuição nos diferentes tecidos da planta em cinco diferentes áreas. Isolados foram caracterizados cultural e morfologicamente, quanto à patogenicidade e virulência, e através de inferências filogenéticas baseadas na sequência parcial do gene gliceraldeído-3-fosfato desidrogenase (GPDH). Houve diferença significativa na freqüência de isolamento de Colletotrichum em função da área de coleta e do tecido da planta. Na localidade de Aldeia (área III) foi observada a maior freqüência de isolamento de Colletotrichum. O limbo maduro foi a parte da planta mais colonizada por Colletotrichum em um maior número de áreas. Colletotrichum asianum, C. fructicola, C. cliviae, C. boninense e duas espécies não identificadas ocorrem como endófitas em mangueira, e C. asianum foi prevalente sobre as demais. Todos os isolados foram patogênicos em frutos de manga. A análise filogenética revelou agrupamentos que foram congruentes com os caracteres morfológicos analisados, porém não agrupou isolados conforme características fenotípicas. Também não foi observado padrão de distribuição das espécies nas diferentes áreas, nem nos tecidos vegetais.
