Controlo biológico do cancro do castanheiro. Deteção, identificação e caracterização do Hypovirus - CHV1

Abstract

O cancro do castanheiro é provocado pelo fungo Cryphonectria parasitica é considerado a principal causa do declínio dos castanheiros na Europa. C. parasitica é um ascomiceta (Diaporthales) nativo do continente asiático. A infeção do castanheiro manifesta-se pelo aparecimento de necroses extensas na casca dos ramos e troncos, que resulta na morte dos castanheiros. A hipovirulência é um método seletivo de controlo biológico do Cancro do Castanheiro, trata-se de uma infeção do fungo C. parasitica com Cryphonectria hypovirus 1 (CHV1), um vírus de dsRNA não encapsulado do género Hypovirus. O controlo biológico com estirpes hipovirulentas é considerado um método eficaz no controlo da doença e promove a recuperação dos castanheiros. A aplicação necessita da produção em laboratório de estirpes hipovirulentas compatíveis com a estirpe virulenta presente no campo e a sua introdução na margem de cancros ativos. Neste estudo pretendeu-se detetar, identificar e caracterizar o hipovirus CHV1 com potencial para integrar programas de controlo biológico do Cancro do castanheiro em Portugal. Com a utilização de métodos moleculares foram identificados e caracterizados 11 hipovirus em isolados brancos de C. parasitica obtidos em cancros no nordeste de Portugal.
