Foundation plants shape the composition of local biotic communities and abiotic environments, but the impact of a plant’s intraspecific variations on these processes is poorly understood. We examined these links in the alpine cushion moss campion (Silene acaulis) on two neighboring mountain ranges in the French Alps. Genotyping of cushion plants revealed two genetic clusters matching known subspecies. The exscapa subspecies was found on both limestone and granite while the longiscapa one was only found on limestone. Even on similar limestone bedrock, cushion soils from the two S. acaulis subspecies deeply differed in their impact on soil abiotic conditions. They further strikingly differed from each other and from the surrounding bare soils in fungal community composition. Plant genotype variations accounted for a large part of the fungal composition variability in cushion soils, even when considering geography or soil chemistry, and particularly for the dominant molecular operational taxonomic units ... : README1a file describing the content of the other files in this archive_README1.txtTable S1_SiteDescriptionGeographical site coordinatesAFLPdataPresence/absence data of 345 AFLP markers for 85 Silene acaulis cushion plantsFungITS1_mrseq98.ecotag.unite.fastaMost represented fungal ITS1 sequence for each of the 9379 MOTUs defined at the 98% identity threshold.
