Welcome to PiriformosporaDB, the Piriformospora indica database.

Piriformospora indica belongs to heterobasidiomycetous order Sebacinales. This group of fungi has a basal position in the Agaricomycotina and includes a wide spectrum of lifestyles ranging from ectomycorrhizae, ericoid, orchid mycorrhizae, to root endophytes.
Recently, Weiss et al., (2004) divided it in two subgroups:

P. indica was positioned by phylogenetic analysis in the subgroup B.

Since then, environmental molecular analyses have unraveled a ubiquitous distribution of very similar sequences within various plants world wide.

This fungus is not an obligate biotroph, but rather facultatively interacts with plants and can grow readily on various synthetic media. It was first isolated from an arbuscular mycorrhizal fungal spore in the 1998 from a desert soil in India (Verma et al.). Its ability to colonize inter- and intracellularly the root cortex of a wide range of vascular plants and to promote their growth makes it an interesting organism for studying mutualistic symbioses, symbiont evolution, and genomic mechanisms accounting for variations in host preferences and microbial lifestyles.

We have therefore sequenced the 24 Mb genome and transcriptome of Piriformospora indica by using 454 pyrosequencing. After automated gene prediction using GeneMark, Augustus and fGenesH, 12,000 gene models were predicted and manually validated in cooperation with the Institute of Bioinformatics and Systems Biology / MIPS, Helmholtz Zentrum München.
Investigating sebacinoid interactions with host plants can greatly improve our understanding of the molecular and biological differences accounting for endophytism, saprophytism and symbiosis.
