Ecology of Phytophthora nemorosa and Phytophthora pseudosyringae in Mixed- Evergreen Forests
Recent research has shown that Phytophthora ramorum is a major threat to California’s coast live oak (Quercus agrifolia) dominated, mixed-evergreen forests (Rizzo and Garbelotto 2003). However, the role that diseases caused by other Phytophthora species play in the ecology of these forest communities is less evident. Surveys in mixed-evergreen forests have revealed two additional Phytophthora s...
متن کاملChemical composition of chestnut cultivars from Spain
Chestnut cultivation and production in Spain has employed grafted seedlings from selected local cultivars. Previously, we have characterised the Spanish cultivars by morphological and molecular markers. We are presenting in this paper the proximate analysis and mineral content for the main Spanish cultivars.A total of 131 sampleswere collected from47cultivars in six important Spanish chestnut p...
متن کاملReal-Time Fluorescent Polymerase Chain Reaction Detection of Phytophthora ramorum and Phytophthora pseudosyringae Using Mitochondrial Gene Regions.
ABSTRACT A real-time fluorescent polymerase chain reaction (PCR) detection method for the sudden oak death pathogen Phytophthora ramorum was developed based on mitochondrial DNA sequence with an ABI Prism 7700 (TaqMan) Sequence Detection System. Primers and probes were also developed for detecting P. pseudosyringae, a newly described species that causes symptoms similar to P. ramorum on certain...
متن کاملDistribution of Phytophthora ramorum, P. nemorosa, and P. pseudosyringae in Native Coastal California Forest Communities
Phytophthora ramorum, causal agent of sudden oak death, is well established over approximately 450 km of native forest along the California coast. In the course of research on this invasive exotic pathogen, two other putatively exotic aerial Phytophthora species, P. nemorosa and P. pseudosyringae, were discovered (Ivors and others 2004, Linzer and others 2006). Little is known about the ecology...
متن کاملSeptoria Canker on Nursery Stock of Populus Deltoides
Septoria musiva Peck is capable of establishing itself on unwounded first-ye ar stems of eastern cottonwood. Natural infections have been observed since 1969 in three forest nurse ries in Mississippi, and inoculations have confirmed that both conidia and ascospores are capable of causing stem infections . This paper offers evide n ce that the fungus Septoria musiva Peck is capable of causing ca...
