dc.description.abstract | 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 particularly true for wild plants
in arcto-alpine biomes. Here, we hypothesized that the bacterial communities
associated with pioneer plants in these regions have major roles in plant health
support, and this is reflected in the formation of climate and host plant specific
endophytic communities. We thus compared the bacteriomes associated with the
native perennial plants Oxyria digyna and Saxifraga oppositifolia in three arcto-alpine
regions (alpine, low Arctic and high Arctic) with those in the corresponding bulk
soils. As expected, the bulk soil bacterial communities in the three regions were
significantly different. The relative abundances of Proteobacteria decreased
progressively from the alpine to the high-arctic soils, whereas those of Actinobacteria
increased. The candidate division AD3 and Acidobacteria abounded in the low Arctic
soils. Furthermore, plant species and geographic region were the major determinants
of the structures of the endophere communities. The plants in the alpine region had
higher relative abundances of Proteobacteria, while plants from the low- and high-
arctic regions were dominated by Firmicutes. 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. | |
