DNA BARCODING

Some DNA fragments are well conserved within a species and variable between species. These are the genetic markers or barcodes.

 

DNA METABARCODING = Next generation sequencing technology (NGS)

DNA metabarcoding is a barcoding extension using the NGS technology. It allows to identify blindly every species present in the sample.

Two types of markers 

– The  “universal” markers allow to do botanical identification blindly on any sample.
– The specific markers created for a particular family or genus.
These markers allow a very precise attribution for the species, even until the sub species of interest
