Mitochondrial genome sequences and comparative genomics of Phytophthora ramorum and P. sojae

Comparative analysis of expressed sequences in Phytophthora sojae.

Phytophthora sojae (Kaufmann and Gerdemann) is an oomycete that causes stem and root rot on soybean (Glycine max L. Merr) plants. We have constructed three cDNA libraries using mRNA isolated from axenically grown mycelium and zoospores and from tissue isolated from plant hypocotyls 48 h after inoculation with zoospores. A total of 3,035 expressed sequence tags (ESTs) were generated from the thr...

Cross-species global proteomics reveals conserved and unique processes in Phytophthora sojae and Phytophthora ramorum.

Phytophthora ramorum and Phytophthora sojae are destructive plant pathogens. P. sojae has a narrow host range, whereas P. ramorum has a wide host range. A global proteomics comparison of the vegetative (mycelium) and infective (germinating cyst) life stages of P. sojae and P. ramorum was conducted to identify candidate proteins involved in host range, early infection, and vegetative growth. Six...

Draft genome sequences of Phytophthora kernoviae and Phytophthora ramorum lineage EU2 from Scotland

Newly discovered Phytophthora species include invasive pathogens that threaten trees and shrubs. We present draft genome assemblies for three isolates of Phytophthora kernoviae and one isolate of the EU2 lineage of Phytophthora ramorum, collected from outbreak sites in Scotland.

Phytophthora ramorum + P. kernoviae = International Biosecurity Failure

Introduction For a scientist, my title may seem a little sensationalist in tone. This is deliberate to draw attention to my issue. And here’s the issue. About six years ago the previously unknown invasive pathogen P. ramorum sp. nov. was found spreading on trees and shrubs in North America and Europe. Almost simultaneously in the U.K. we found another previously unknown invasive Phytophthora on...
