All generated raw HTS sequences are deposited in the Sequence Read Archive under the BioProject PRJNA611057. A database including 1160 unique 5S-IGS sequences (unaligned fasta file), the corresponding taxonomy file (in Mothur compatible format), and an Excel file (providing correspondence between clone codes, GenBank accessions and geographic origin) can be downloaded at (https://doi.org/10.6084/m9.figshare.12016272.v1).
All RAxML inferred trees can be downloaded in NEWICK format at (https://doi.org/10.6084/m9.figshare.12016317.v1). Other relevant data are within the paper and its Supplementary Files.
