Phytophthora infestans Assembly and Gene Annotation
About the Phytophtora infestans genome
Phytophthora infestans is the causal agent of the late potato blight disease and also infects tomatoes and other members of the Solanaceae. This oomycete caused several major crop losses including the Great Famine in Ireland. This pathogen can affect a large area reproducing asexually through spores. P. infestans sporangia are carried by the wind until they land in plant tissue. If the conditions are wet and cool they release their zoospores that can swim until encysting in the host. If conditions are warmer a germ tube from the sporangium can penetrate the plant.
The assembly is available from the EMBL/Genbank/DDBJ databases under the accession GCA_000142945.1
The protein coding genes in this site are a direct import from Broad Institute and MIT under the "Phytophthora infestans Sequencing Project". The data was imported in December 2010. Non coding RNA genes have been annotated using tRNAScan-SE (Lowe, T.M. and Eddy, S.R. 1997), RFAM (Griffiths-Jones et al 2005), and RNAmmer (Lagesen K.,et al 2007); additional analysis tools have also been applied.
The ESTs sequenced from different stages of pathogen infection were also downloaded from dbEST and aligned to the genome using exonerate.
