Investigating the Spatiotemporal Genetic Structure of Phytophthora capsici in Michigan.
ABSTRACT Phytophthora capsici isolates were recovered from pepper and cucurbit hosts at seven locations in Michigan from 1998 to 2000. Isolates were characterized for compatibility type (CT), mefenoxam sensitivity (MS), and amplified fragment length polymorphism (AFLP) marker profiles. In total, 94 AFLP bands were resolved. Individual populations were highly variable. Within populations, 39 to ...
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 کاملMefenoxam Insensitivity and the Sexual Stage of Phytophthora capsici in Michigan Cucurbit Fields.
ABSTRACT The potential for outcrossing, occurrence of oospores, and inheritance of mefenoxam sensitivity was assessed in naturally occurring populations of Phytophthora capsici. Between 1997 and 1998, 14 farms were sampled, with 473 isolates recovered from cucurbit hosts and 30 from bell pepper. The A1 and A2 compatibility types were recovered in a roughly 1:1 ratio in 8 of 14 farms with sample...
متن کاملInterspecific 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 کاملMolecular characterization and functional analysis of the Nep1-like protein-encoding gene from Phytophthora capsici.
Phytophthora capsici is an aggressive plant pathogen that affects solanaceous and cucurbitaceous hosts. Nep1-like proteins (NLPs) are a group of effectors found particularly in oomycetes and considered important virulence factors. We identified an NLP gene (phcnlp1) from the highly virulent P. capsici strain Phyc12 that had an encoded polypeptide of 476-amino acid residues and a predicted molec...
