  • a Endophytic sequences with >300 bp were retrieved from peer-reviewed manuscripts available in the ISI Web of Science and PubMed databases (as of 1 March 2014).

  • b Based on comparison with the small-subunit rRNA SILVA database (version 115) (372) by using the SINA aligner (364).

  • c Candidate division phyla.
