Using Herbarium‐Derived DNAs to Assemble a Large‐Scale DNA Barcode Library for the Vascular Plants of Canada

Abstract

Our DNA barcode library represents an unparalleled resource for metagenomic and ecological genetic research working on temperate and arctic biomes. An observed decline in sequence recovery with specimen age may be associated with poor primer matches, intragenomic variation (for ITS2), or inhibitory secondary compounds in some taxa.
