Pythium vexans Assembly and Gene Annotation

About the Pythium vexans Genome

Pythium vexans is a plant pathogen and it causes canker, damping-off and rot disease in many economically important crops including rubber trees, potato and sugar cane. It belongs to the group oomycetes which was originally classified among the fungi, due to its morphological and functional similarities. They are now classifed as protists based on modern insights on phylogentic relationship with photosynthetic organisms such as brown algae and diatoms.


The assembly for the genome was provided by Pythium Genome Database and is also available from the EMBL/Genbank/DDBJ databases under the accession GCA_000387545.2 . The genome is ~33Mb and is assembled into 3685 scaffolds.


11,957 gene models were imported from Pythium Genome Database and 35 ncRNA were predicted by Ensembl pipeline.
