Molecular Detection of Phytophthora ramorum, the Causal Agent of Sudden Oak Death in California, and Two Additional Species Commonly Recovered from Diseased Plant Material.

ABSTRACT Sudden oak death is a disease currently devastating forest ecosystems in several coastal areas of California. The pathogen causing this is Phy-tophthora ramorum, although species such as P. nemorosa and P. pseudo-syringae often are recovered from symptomatic plants as well. A molecular marker system was developed based on mitochondrial sequences of the cox I and II genes for detection ...

DNA Fingerprinting Based on Repetitive Sequences of Iranian Indigenous Lactobacilli Species by (GTG)5- REP-PCR

Background and Objective: The use of lactobacilli as probiotics requires the application of accurate and reliable methods for the detection and identification of bacteria at the strain level. Repetitive sequence-based polymerase chain reaction (rep-PCR), a DNA fingerprinting technique, has been successfully used as a powerful molecular typing method to determine taxonomic and phylogenetic relat...

Development and application of a PCR-based ‘molecular tool box’ for the identification of Phytophthora species damaging forests and natural ecosystems

A PCR-based ‘molecular tool box’, based on a region of the ras-related protein gene Ypt 1, was developed for the identification of 15 Phytophthora species that damage forests and trees: P. cactorum , P. cambivora , P. cinnamomi , P. citricola , P. europaea , P. inundata , P. lateralis , P. megasperma , P. nemorosa , P. kernoviae , P. pseudosyringae , P. psychrophila , P. quercina , P. ramorum a...

Molecular diversity of Symbiodinium spp. within six coral species in Larak Island, the Persian Gulf

Reef-building coral harbor communities of photosynthetic taxa of the genus Symbiodinium (zooxanthellae). The genus Symbiodinium is currently classified into nine genetic clades (A–I). Various corals harbor different Symbiodinium clades; some show specificity to a single strain. Coral and their zooxanthellae are sensitive to environmental stresses. In the Persian Gulf, coral reefs are subject to...
