Abstract

Abstract: Global warming is driving plant range shifts towards higher latitudes, where plants encounter different light environment (photoperiod and light spectral quality) than that to which they are adapted. Light environment may indirectly influence the belowground part of the plant, where trees associate with ectomycorrhizal (ECM) and other biotrophic fungi. We studied joint impacts of warming and light climate on Scots pine ( Pinus sylvestris ) and its root-associated fungi in a reciprocal transplantation study, where pine seedlings from southern and northern tree populations were grown under similar experimental temperature in southern (60°N) and northern (69°N) Finland. Based on fungal ITS rDNA, the abundance of Basidiomycota, and ECM fungi in particular, was highest in the roots of southern pines in the south and in northern pines in the north, and seedling biomass was determined by population origin. Our results imply that root-associated fungi may respond differentially in native vs. non-native light environment of the host plant.
