RT Journal Article SR Electronic(1) A1 Hugenholtz, Philip A1 Huber, ThomasYR 2003 T1 Chimeric 16S rDNA sequences of diverse origin are accumulating in the public databases JF International Journal of Systematic and Evolutionary Microbiology, VO 53 IS 1 SP 289 OP 293 DO https://doi.org/10.1099/ijs.0.02441-0 PB Microbiology Society, SN 1466-5034, AB A significant number of chimeric 16S rDNA sequences of diverse origin were identified in the public databases by partial treeing analysis. This suggests that chimeric sequences, representing phylogenetically novel non-existent organisms, are routinely being overlooked in molecular phylogenetic surveys despite a general awareness of PCR-generated artefacts amongst researchers., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.02441-0
