Plants Assemble Species Specific Bacterial Communities From Common Core Taxa in Three Arcto-Alpine Climate Zones
Evidence for the pivotal role of plant-associated bacteria to plant health and productivity has accumulated rapidly in the last years. However, key questions related to what drives plant bacteriomes remain unanswered, among which is the impact of climate zones on plant-associated microbiota. This is...

A highly-conserved shared set of ubiquitous bacterial taxa (core bacteriome) was found to occur in the two plant species. Burkholderiales, Actinomycetales and Rhizobiales were the main taxa in this core, and they were also the main contributors to the differences in the endosphere bacterial community structures across compartments as well as regions. We postulate that the composition of this core is driven by selection by the two plants. peerReviewed Article in Journal/Newspaper Arctic Oxyria digyna Saxifraga oppositifolia JYX - Jyväskylä University Digital Archive Arctic |
