Um bioensaio rápido e sensível na deteção de Phytophthora a partir do solo de c...
Machado, Júlia Melo; Coelho, Valentim; Gouveia, Maria EugéniaA doença da tinta do castanheiro (DTC) é uma doença endémica nos soutos portugueses apresentando surtos epidémicos cíclicos que causam grande mortalidade. Os Oomicetas, Phytophthora cinnamomi e Phytophthora cambivora são os parasitas mais frequentemente associados com a DTC embora outras espécies de Phytophthora possam também estar presentes. Os parasitas atacam as raízes e todo o seu ciclo de vida ocorre na ri...

Gouveia, Maria Eugénia; Moura, Luísa; Machado, Júlia Melo; Coelho, ValentimChestnut Ink Disease (CID) is a destructive and a lethal disease of sweet chestnut (Castanea sativa Mill.) that is associated with different soil borne Phytophthora species. CID is very difficult to control because cultural and chemical measures provide limited effects and didn´t prevent disease spread. The aim of this study was to validate different methodologies used for Phytophthora detection from soil, symp...
Detection and identification of Phytophthora sp. associated with ink disease of...
Machado, Júlia MeloOne of the biggest threats for the chestnut tree in Portugal and in Europe is the ink disease. The disease is caused by two Phytophthora species (Phytophthora cinnamomi and Phytophthora cambivora). These root parasites have biological and epidemiological characteristics that provide them with rapid adaptation to the environmental conditions and have a high capacity for survival. With this work we intend to deve...
In vitro antagonism evaluation of endophyte Chaetomium aureum against Cryphonec...
Coelho, Valentim; Machado, Júlia Melo; Guerra, Inês; Gouveia, Maria EugéniaThe European chestnut tree (Castanea sativa Mill.) is threatened by various microfungi that affect its production. In the trunk and branches infected by chestnut blight (Cryphonectria parasitica (Murril) Barr.) it was observed the presence of several microfungi that co-occur in the presence of the disease among which the endophytic fungus Chaetomium aureum Chivers. Many species of the genus Chaetomium are descr...
