Survey and analysis of microsatellites from transcript sequences in Phythoptora species: frequency distribution and potential as markers for the phylum Oomycota.

Members of the genus Phytophthora are notorious pathogens with world-wide distribution. The most devastating species include P. infestans, P. ramorum and P. sojae.
In order to develop molecular methods for routinely characterizing their populations and to gain a better insight into the organization and evolution of their genomes, we used an in silico approach to survey simple sequence repeats (SSRs) content in transcript sequences from these three species.
Primers were designed for the SSRs detected, and all SSR-containing sequences along with their corresponding primers and a brief description of the SSR and the virtual PCR product were deposited in this database. Searches can be performed by organism in combination with SSR repeat type, motif and length. Sequences are freely accessible and can be downloaded in FASTA format.
