Figure S4 Identification of ITS-VTs from IIS of Glomus genus with maximum likelihood method. ITS-VTs were determined with representative IIS sequence clusters (97% similarity) based on 50% support value; for sequence clusters under 50% bootstrap support, further 90% similarity was used to assign these sequences into ITS-VTs.
