Interspecific hybridization and apomixis between Phytophthora capsici and Phytophthora tropicalis.
Phytophthora capsici and the closely related Phytophthora tropicalis infect different hosts that have documented overlapping geographical distributions. Phytophthora capsici attacks annual vegetable hosts whereas P. tropicalis has been recovered from woody perennial hosts. Our objective was to test whether interspecific hybridization is possible and to characterize the resulting progeny. Crosse...
متن کاملThermal inactivation of Phytophthora capsici oospores.
BACKGROUND Phytophthora capsici is a major fungal plant pathogen that causes root and crown rot of pepper crops and its oospores are the most resistant propagules. OBJECTIVES To evaluate the effect of different temperature regimes and exposure times on the survival of P. capsici oospores. METHODS Thermal inactivation treatments simulated field conditions, through the use of different consta...
متن کاملSurvival and spread of Phytophthora capsici in Coastal Peru.
Phytophthora capsici is a soilborne pathogen that causes significant losses to pepper production in Peru. Our objective was to investigate the mechanisms by which P. capsici is able to survive and spread. During 2005 to 2007, 227 isolates of P. capsici were collected from four species of pepper (Capsicum annum, C. baccatum, C. chinense, and C. pubescens) and tomato (Solanum lycopersicum) at 33 ...
متن کاملThe Spatiotemporal Genetic Structure of Phytophthora capsici in Michigan and Implications for Disease Management.
Root, crown, and fruit rot caused by Phytophthora capsici Leonian is a limiting factor for the production of peppers, tomatoes, and cucurbit crops in Michigan and the United States. Like many species in the genus Phytophthora, P. capsici has the potential for rapid polycyclic disease development from a limited amount of initial inoculum (6). P. capsici produces caducous sporangia that can be sp...
متن کاملThe expansion of Phytophthora clade 8b: three new species associated with winter grown vegetable crops
Despite its association with important agricultural crops, Phytophthora clade 8b is a poorly studied group of species. The clade currently consists of three officially described species (Phytophthora porri, P. brassicae and P. primulae) that are host-specific pathogens of leek, cabbages and Primula spp., respectively. However, over the past few decades, several other clade 8b-like Phytophthoras...
