Fungal plant pathogens in Portugal: Alternaria dauci.
A leaf blight of carrot (Daucus carota) caused by Alternaria dauci was found in Alentejo (Ourique, Portugal). Morphological characteristics of the fungus are described.
متن کاملAntifungal activity of diketopiperazines extracted from Alternaria alternata against Plasmopara viticola: an ultrastructural study.
Three dipeptides, belonging to the family of diketopiperazines (DKPs), were extracted from broth culture of the grapevine endophyte Alternaria alternata, and were tested against Plasmopara viticola on leaves of grapevine plants grown in greenhouse. DKPs, used at different concentrations (10(-3), 10(-4), 10(-5) and 10(-6)M) both singularly and in mixtures, demonstrated real effectiveness in inhi...
متن کاملFitness effects of Alternaria dauci on wild carrot in The Netherlands.
In a field experiment with a susceptible population of annual wild carrot (Daucus carota) from Iran, artificial inoculations with the fungal pathogen A. dauci led to a strong and very significant increase of the diseased leaf area. The pathogen caused a very significant decrease in fecundity and seed survival of the host. This considerable fitness reduction by A. dauci would suggest that introg...
متن کاملPartial Resistance of Carrot to Alternaria dauci Correlates with In Vitro Cultured Carrot Cell Resistance to Fungal Exudates
Although different mechanisms have been proposed in the recent years, plant pathogen partial resistance is still poorly understood. Components of the chemical warfare, including the production of plant defense compounds and plant resistance to pathogen-produced toxins, are likely to play a role. Toxins are indeed recognized as important determinants of pathogenicity in necrotrophic fungi. Parti...
متن کاملAn Update on 2,5-Diketopiperazines from Marine Organisms
2,5-Diketopiperazines (2,5-DKPs) are an important category of structurally diverse cyclic dipeptides with prominent biological properties. These 2,5-DKPs have been obtained from a variety of natural resources, including marine organisms. Because of the increasing numbers and biological importance of these compounds, this review covers 90 marine originated 2,5-DKPs that were reported from 2009 t...
