Hyaloperonospora arabidopsidis (HyaAraEmoy2_2.0)

Hyaloperonospora arabidopsidis Assembly and Gene Annotation

About the Hyaloperonospora arabidopsidis genome

Hyaloperonospora arabidopsidis is a pathogen of the model plant Arabidopsis thaliana and food crops belonging to the family Cruciferae and cause downy mildew disease. They belong to the class Oomycetes, belong to the kingdom Stramenopila, which includes brown algae and diatoms. Although they share morphological and ecological similarities with fungi, they evolved independently to colonize plants. They belong to a group of “downy mildew” pathogens, comprising more than 800 species that cause disease on hundreds of plant species.


The is genome assembly is available from the EMBL/Genbank/DDBJ databases under the accession GCA_000173235.2.


The protein coding genes in this site are a direct import of annotation available at VBI Microbial database( V8.3.2). 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 007); additional analysis tools have also been applied.
