Description
The oomycete, Phytophthora ramorum, is a plant pathogen which causes sudden oak death. This disease affects oak trees as well as over 40 other plant genera. It is an emerging plant pathogen first observed in North America but also widespread in Europe, causing stem cankers on trees, and leaf blight on ornamentals and forest shrub species. There are no treatments currently available that are effective against P. ramorum. While some fungicides can suppress the symptoms, none can kill the pathogen. The genome sequence was published in 2006 along with that of the soybean pathogen Phytophthora sojae. Comparison of the two genomes reveals a rapid expansion and diversification of many protein families associated with plant infection such as hydrolases, ABC transporters, protein toxins, proteinase inhibitors, and, in particular, a superfamily of 700 proteins with similarity to known oomycete avirulence genes.
