Abstract/Summary

Following fungicide treatment of young Scots pine trees in Scotland targeted at Dothistroma septosporum, foliar fungal endophytic communities were investigated with culture-based methods and metabarcoding of cDNA. Compared to negative controls, application of fungicides resulted in significant reductions in the size and diversity of endophytic communities with alterations to their taxonomic composition. While most taxa showed reductions in frequency and abundance across samples, Anthostomella pinea and a Preussia sp. temporarily increased. Thirteen taxa were identified using culturing, compared to 569 by metabarcoding (with 41 taxa accounting for 89.4 % of the total reads). Dothistroma septosporum and the reportedly unculturable Lophodermella conjuncta both contributed significantly to differences observed using metabarcoding but occurred at low levels or were absent, respectively, in the culture-based study. The persistent effects we observed of fungicides on the endophytic fungal community have possible practical implications for management of tree seedlings in the nursery.
