Online World Phytophthora Genetic Resource
Collection Database at UCR
The World Phytophthora Collection at the University of California
, Riverside currently contains about 7500 isolates (March 2007) representing
over 90 described species and many undescribed taxa. These isolates
are from worldwide sources and a wide range of hosts. The collection
is the only truly global resource for research on Phytophthora, one
of the most devastating plant pathogens on this planet. As such it
is now the only remaining comprehensive collection of genetic diversity
representative of this extremely important group of plant pathogens.
It was started around 1962 and gradually became established as an
important resource for Phytophthora research. Since 1981 it has been
under the curatorship of Professor Michael Coffey and in the last
25 years it has increased dramatically both in size and genetic diversity.
It has acquired important collections from worldwide sources. The
collection includes a genetically diverse of collection of ~2000 isolates
of P. infestans, cause of late blight of both potatoes and tomatoes.
This species is one of the most dangerous plant pathogens in the world.
PhytID - Identification of Plant Pathogenic Phytophthora
Species by ITS Fingerprinting
A database of molecular data, represents a novel and highly effective
method of species determination based on comparisons of restriction
enzyme digest products of the internal transcribed spacer (ITS)
regions of rDNA.
Joint Genome Institute
A Unique resources for Genome sequence assembly. Genome sequencing
efforts at JGI have focused on two species, Phytophthora sojae and
P. ramorum. P. sojae has been developed as a model species for the
genus, having in place excellent genetic and genomics resources
(including genetic maps, BAC libraries, and EST sequences), as well
as having a well organized community of researchers. The genome
assembly version 1.0 of the P. ramorum genome, was generated using
the whole genome shotgun strategy. This assembly release was annotated
using the JGI automated annotation pipeline. Gene models and associated
transcripts/proteins are predicted or mapped using a variety of
tools based on cDNA, protein homology and ab initio methods. Conservation
between the genomic sequences of P. sojae and P. ramorum provided
additional support for the predicted gene models. Gene functions
have been automatically assigned based on homology to known genes.
Phytophthora infestans Database
The Phytophthora infestans sequencing project, Their goal is to
release an annotated assembly with 8X genome sequence coverage for
Phytophthora infestans strain T30-4.
Phytophthora functional genome databse
The Phytophthora Functional Genomics Database is a publicly accessible
resource that will include functional assays and expression data,
combined with transcript analysis and annotation. PFGD builds upon
data available from the Phytophthora Genome Consortium and the Syngenta
Phytophthora Consortium as well as all publicly available P. infestans
transcript data that are analyzed and annotated using NCGR's XGI
System. Gene-sequences derived from XGI will be linked to the full-length
ORF's used in the functional assays and expression experiments.
PFGD will also contain all pertinent metadata and curated annotations
concerning these experiments. The knowledge gained from these studies
will provide significant insight into key molecular processes regulating
an economically important pathosystem and will provide novel tools
for improvement of disease resistance in crop plants.
Oomycete Genomics Database
The Oomycete Genomics Database is a publicly accessible resource
that includes functional assays and expression data, combined with
transcript and genomic analysis and annotation. OGD builds upon
data available from the Phytophthora Genome Consortium, Syngenta
Phytophthora Consortium and the Phytophthora Functional Genomics
Database. Data are analyzed and annotated using NCGR's XGI System.
VBI Microbial Database And Phytophthora Soybean EST database
VBI Microbial Database at VBI hosts data from a range of plant pathogenic
oomycetes, fungi and bacteria primarily those under study at VBI.
The phytophthora soybean EST database, contains 10 libraries from
P.sojae (sHA,sHB,sMA,sML,sMY,sMC,sZG,sZO,sZS,iMY) having 33350 raw
sequences. These sequences were clustered and assembled and data
analysised. Recently all publicly avaialble soybean unigenes(37,465)
are added to this database. The whole dataset had interproscan and
signalP analysis. The Phytophthora sequences are linked to the genome
The Wellcome Trust Sanger Institute Pathogen Genomics Group
Pathogen Genomics aims to sequence the genomes of organisms relevant to human and animal health.
It has a large portfolio of projects ranging from bacterial plasmids and phage, through
bacterial genomes and protist parasites to helminths and insect vectors. The projects
themselves range from EST sequencing through comparative genomic sequencing, to fully
Virginia Bioinformatics Institute - Oomycete Molecular Genetics Research Collaboration Network (OMGN)
The oomycete molecular genetics community has a strong culture of collaboration and communication, and sharing of techniques
and resources. With the recent blossoming of genetic and genomic tools for oomycetes, many new
investigators, from a variety of backgrounds, have become interested in oomycete molecular genetics
and genomics. The goals of the Oomycete Molecular Genetics Research Collaboration Network is to
facilitate the integration of these investigators into the community and to further strengthen the
cooperative culture of this community.
Virginia Bioinformatics Institute - Dissecting Soybean Resistance to Phytophthora
The Dissecting Soybean Resistance to Phytophthora project focuses on the mechanisms of
quantitative resistance of soybean against the oomycete pathogen Phytophthora sojae, which
is one of the most damaging pathogens of soybean crop. .
United States Department of Agriculture (Global Phytophthora Network)
The objective of this project is to develop a fully integrated website for the genus
Phytophthora that would include full species description, host ranges of specific species,
their distribution and molcular characterization.
Phytophthora infestans Mitochondrial Genome Project - TIGR Database
North Carolina State University and TIGR are collaborating on sequencing and annotation of haplotypes of the mitochondrial genome P. infestans.
Haplotypes could be correlated with virulence and resistance to pesticides and used in epidemiological
studies. In addition, whole mitochondrial genome sequence analysis will be useful in studies to examine
molecular evolution in the pathogen.

Department of Plant Pathology, Michigan State University - Controlling Phytophthora Disease on Vegetable Crops
Phytophthora capsici, a soil mold that causes crown, fruit, and root rot, can be easily spread across and
within regions via water. It infects cucumber, melon, squash, pumpkin, tomato, pepper, eggplant, lima, snap and wax
bean crops. The goal of this project is to develop and implement a comprehensive management strategy for Phytophthora
that relies on multiple tools rather than intensive pesticide use. Objectives include: limit the spread of Phytophthora,
identify and develop Phytophthora-resistant varieties, develop new techniques for Phytophthora control including soil
amendments, mulches, crop rotation, and water management, test currently labeled fungicides, biological control agents,
and new chemistries for activity against Phytophthora, integrate chemical, biological, and cultural growing techniques
and conduct on-farm research trials and extension meetings.
