Abstract
Phytophthora parasitica is a soilborne oomycete pathogen capable of infecting a wide range of plants, including many solanaceous plants. In a first step towards large-scale gene discovery, we generated expressed sequence tags (ESTs) from a cDNA library constructed using mycelium grown in synthetic medium. A total of 3568 ESTs were assembled into 2269 contiguous sequences. Functional categorization could be performed for 65.45% of ESTs. A significant portion of the transcripts encodes proteins of common metabolic pathways. The most prominent sequences correspond to members of the elicitin family, and enzymes involved in the lipid metabolism. A number of genes potentially involved in pathogenesis were also identified, which may constitute virulence determinants.
