The structure of the mycobiota in seed samples from different host tree species. PCA plots are based on fungal genera revealed by the Taylor, Tedersoo and ONT dataset and their CLR-normalized abundances. The samples are colored according to host tree species, with filled points representing angiosperm and hollow points representing gymnosperm samples. The full set of genera identified within each dataset were used for the genus-level PCA analyses (Taylor: n = 244, Tedersoo: n = 217, ONT: n = 226)
