Description
Krawczyk and co-authors test whether chloroplast genomes can serve as universal ID cards for grasses and their kin. DNA barcoding promises species identification from tissue scraps, but only if each species' genome carries marks its relatives lack. The team aligned full plastid genomes for 793 species across 96 genera of the order Poales and catalogued each species' unique mutations.
The spread was wide. Many species carry plenty of diagnostic marks, yet some carry none at all, making them invisible to this method however complete the genome. Certain genera are repeat offenders. The study, the largest of its kind, tells practitioners where super-barcoding works, where it fails, and where other markers must take over.
