Spartina rhizosphere Raw sequence reads

Here, we hypothesized that the heightened resistance of polyploid Spartina species to PAH contaminants is partly related to concomitant shifts in the root-associated microorganisms. We selected four Spartina species: the parental species Spartina alterniflora (2n=6x=62) and S. maritima (2n=6x=60), their interspecific sterile hybrid S. x townsendii (2n=6x=62) that appeared and emerged at the end of the 19th century and the allopolyploid derivative S. anglica that subsequently appeared following genome doubling (2n=12x=120, 122, 124). These different Spartina species were grown in salt marsh sediments contaminated or not with phenanthrene, after which the bacterial 16S rRNA gene and fungal ITS region of the rhizosphere soil were amplified and sequenced.
