| Abstract： | Background and aimsThe introduced lineage of Phragmites australis (haplotype M) in North America outcompetes the native lineage (haplotype E). Previous studies have found that haplotype M is situated on the fast side of the trait economic spectrum compared to haplotype E in North America and Europe. The present study evaluated the plant traits and associated soil microbes of introduced and native Phragmites lineages using a common garden experiment.MethodsFour geographic groups, including the introduced lineage of North America (NAint, haplotype M), native lineage of North America (NAnat, haplotype E), European group (EU, haplotype M) and northwestern China group (CHN, haplotype M), were studied in two life-history stages - growing period and withering period.ResultsNo trait differences were observed among the four groups. The difference existed in the soil microbial structure. The soils derived from the four groups had different bacterial generic structures. NAnat gathered more plant pathogenic and ectomycorrhizal fungi in the growing period. In the withering period, NAint accumulated more plant pathogenic fungi, while NAnat accumulated more arbuscular mycorrhizal fungi. The soil microbial structure was different among NAint, EU and CHN despite the same haplotype.ConclusionThe interaction between plant traits and the soil microbes seemed weak. However, the long-term effects of microbial transition on the introduced and native lineages are unknown, and the potential plant-soil interactions need further exploration. |
