Plant Conservation Hologenomics in the Hartvig Group

The Plant Conservation Hologenomics system applies the hologenomics concept to understand the role of microbionts in ecology and evolution of wild plant species, and works on translating the findings into improved conservation plans for threatened taxa.

Distribution and adaptation

Does the range of microorganisms plants associate with, determine their habitat range? We compare distribution-wide microbiome associations among Platanthera orchid species.

Hologenomic orchid conservation

We investigate the correlation between soil types, genotypes and microbiont communities in native Danish orchids to understand their complex habitat requirements and improve conservation plans.

Orchid-mycorrhizal evolution

We investigate how specialization to different fungi across the large terrestrial orchid genus Platanthera has shaped diversification and speciation patterns.

Hybridization and conservation genomics

We apply population genomics to unravel how hybridization and landscape features shape speciation and diversity patterns in vulnerable orchids in North America and Northern Europe.
