Resumo: In the study of the fungi associated to Platypus cylindrus, several fungi were isolated from the insect and its galleries in cork oak, among which three species of Raffaelea. Morphological and cultural characteristics, sensitivity to cycloheximide and genetic variability had been evaluated in a set of isolates of this genus. On this basis R. ambrosiae and R. montetyi were identified and a third taxon segregated witch differs in morphological and molecular characteristics from the previous ones. In this work we present and discuss the parameters that allow the identification of specimens of the three taxa. The role that those ambrosia fungi can have in the cork oak decline is also discussed taking into account that Ophiostomatales fungi are pathogens of great importance in trees, namely in species of the genus Quercus.

Avaliaram-se características morfológicas e culturais, sensibilidade à ciclohexamida e variabilidade genética num conjunto de isolados do género. Foram identificados R. ambrosiae e R. montetyi e segregou-se um terceiro táxone que difere em características morfológicas e moleculares dos dois anteriores. No presente trabalho são apresentados e discutidos os parâmetros que permitem identificar espécimes dos três táxones. É ainda discutido o papel que estes fungos ambrósia podem ter no declínio do sobreiro, sabido que fungos Ophiostomatales são patogénios de grande importância em plantas lenhosas, nomeadamente em espécies do género Quercus.Sociedade de Ciências Agrárias de Portugal2018-11-18T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.19084/rca.15606por2183-041X0871-018XInácio, Maria de LurdesHenriques, JoanaLima, ArlindoSousa, Edmundoinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-06T09:23:46Zoai:ojs.revistas.rcaap.pt:article/15606Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:30:32.699288Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
