Resumo: In Brazil, Colletotrichum gloeosporioides is associated with a complex of symptoms in coffee culture. Although this pathogen had its pathogenesis observed and identified, its importance has still been questioned due to its several endophytic forms, raising doubts as to the real importance of the pathosystem. The aim of this study was to demonstrate, by using an isolate transformed with the gene gfp, the infection and colonization capability of C. gloeosporioides in coffee seedlings. After the fourth day of inoculation, manifestation of symptoms as punctual necrosis could be observed, which progressed during the evaluation period, culminating in the death of seedlings. Epifluorescence microscopy confirmed the presence of the pathogen in the seedlings, as well as the visualization of internal colonization of tissues, acervulus formation and conidium production, confirming that it was responsible for the observed symptoms.

Apesar da observação e da identificação da patogenicidade deste, o patógeno ainda tem sua importância questionada, devido às várias formas endofíticas do mesmo, levantando dúvidas sobre a real importância do patossistema. O presente trabalho teve como objetivo demonstrar por meio da utilização de um isolado transformado com o gene gfp a capacidade de infecção e colonização de C. gloeosporioides em plântulas de café. Pode-se observar após o quarto dia da inoculação a exteriorização de sintomas como necrose pontuais as quais progrediram durante o período de avaliação, culminando na morte das plântulas. Por meio de microscopia de epifluorescencia pode-se confirmar a presença do patógeno nas plântulas, assim como visualizar a colonização interna do tecido, a formação de acérvulos e produção de conídios, confirmando que o mesmo foi o responsável pelos sintomas observados.Grupo Paulista de Fitopatologia2018-05-15T16:37:00Z2018-05-15T16:37:00Z2015-04info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfARMESTO, C. et al.
