Quality and metadata annotations of fungal ITS sequences by mycorrhiza types.

1

all sequences belonging to EcM lineages regardless of isolation source;

2

all sequences belonging to Glomeromycota, except Geosiphon;

3

all sequences derived from roots (with or without a culturing step) of the respective host plants;

4

Chimeric sequences consist of two or more fragments of fungal sequences and are therefore not assigned below the kingdom level;

5

nd, not determined;

6

Annotated–sum of original annotations and metadata provided in the course of this study;

7

formation of coils in ErM, formation of pelotons, stimulation of germination or development in OM.
