Is There a Key Primer for Amplification of Core Land Plant DNA Barcode Regions (rbcL and matK)? [PDF]

open access: yesEcol Evol
We use in silico PCR to select and measure the amplification capability of primer. We tested 366 and 489 published primers for the rbcL and matK regions, respectively, using sequences from 8463 different land plant species. Our results indicate a set of primers that effectively cover all land plant sequences, particularly for the rbcL region.
