Oomycete genomics
Oomycete genomics
Genome sequence
drafts of a number of oomycete species have been completed and several others are in progress. The sequenced species include notorious plant pathogens of importance to world agriculture (see Lamour et al. 2007 for a recent review).
Phytophthora capsici, Phytophthora infestans, and Phytophthora sojae infect diverse crops,
such as pepper, potato, and soybean, respectively. Phytophthora ramorum affects native and
ornamental woody plants resulting in environmental damage. The downy mildew,
Hyaloperonospora arabidopsidis (previously H. parasitica), is a pathogen of Arabidopsis thaliana and figures prominently
in research on this model plant.
Phytophthora infestans genome project
Overview
The 240 Mbp genome of Phytophthora infestans was sequenced, assembled and annotated
by Chad Nusbaum's team at the MIT Broad Institute in collaboration with the P. infestans research
community. An analysis of the genome sequence, authored by over 90 scientists from 34 institutions, was published in September 2009:
