Long-Read Sequencing Could Improve the Sensitivity and Precision of 16S Studies Says Jackson Lab Study

It’s time to revisit the way scientists are using 16S rRNA gene sequencing to study microorganisms, according to a team of Jackson Laboratory researchers.  Popular targets for taxonomy and phylogeny studies because of their highly conserved nature, amplified sequences of the 16S ribosomal RNA genes can be compared with reference databases to determine the identity of the microorganisms that comprise a metagenomic sample. Sequences with a > 95% match are generally considered to represent the same genus, for example, while > 97% matches are considered the same species. However, these matches are often made by sequencing only part of the nine-region, ~1500 bp…
