PCR assays that identify the grapevine dieback fungus Eutypa lata.
Eutypa lata is the causal fungal agent of Eutypa dieback, a serious grapevine necrotic disease. The erratic and delayed (1 to 2 months) appearance of characteristic conidia on culture media and the presence of numerous microorganisms in decaying wood make it difficult either to identify or to detect E. lata in grapevine wood samples. We designed six pairs of PCR primers for diagnosis of E. lata...
متن کاملIdentification of gadoid species (Pisces, Gadidae) by PCR-RFLP analysis.
A rapid PCR-RFLP analysis was optimized to identify the presence of 3 closely related gadoid fish species: Alaska pollack Theragra chalcogramma, Pacific cod Gadus macrocephalus and Atlantic cod Gadus morhua in commercial seafood products. Gadoid universal primers were designed for PCR amplification of a 558-bp fragment encoding the mitochondrial cytochrome b gene. Without purification of the PC...
متن کاملPathogenesis of Eutypa lata in grapevine: identification of virulence factors and biochemical characterization of cordon dieback.
Eutypa lata is a vascular pathogen of woody plants. In the present study we (i) determined which component(s) of the cell wall polymers were degraded in naturally infected grapevines and in artificially inoculated grape wood blocks; (ii) compared the pattern of wood decay in the tolerant grape cv. Merlot versus the susceptible cv. Cabernet Sauvignon; and (iii) identified secondary metabolites a...
متن کاملidentification of sarcocystis gigantea by pcr- rflp
sarcocyst is one of the most important protozoa belonged to apicomplexa. this parasite is prevalent among warm blooded animals throughout the world. in the present work, sarcocystis gigantea was identified by amplification of 18s rrna gene using pcr- rflp. in this regard macroscopic cysts of sarcocystis were collected from esophagus and intra costal muscles of sheep in shahriar slaughterhouse. ...
متن کاملMicrosatellite markers for the grapevine pathogen, Eutypa lata.
We isolated and characterized nine polymorphic microsatellite markers for Eutypa lata, a fungal pathogen responsible for Eutypa dieback of grapevine, in populations from two California vineyards (24 isolates per vineyard). Allele frequency ranged from two to 11 alleles per locus and haploid gene diversity ranged from 0.33 to 0.83. All samples comprised unique haplotypes. Our results suggest tha...
