DNA barcoding exposes a case of mistaken identity in the fern horticultural trade.
Abstract
Using cheilanthoid ferns, we provide an example of how DNA barcoding approaches can
be useful to the horticultural community for keeping plants in the trade accurately
identified. We use plastid rbcL, atpA, and trnG-R sequence data to demonstrate that
a fern marketed as Cheilanthes wrightii (endemic to the southwestern USA and northern
Mexico) in the horticultural trade is, in fact, Cheilanthes distans (endemic to Australia
and adjacent islands). Public and private (accessible with permission) databases contain
a wealth of DNA sequence data that are linked to vouchered plant material. These data
have uses beyond those for which they were originally generated, and they provide
an important resource for fostering collaborations between the academic and horticultural
communities. We strongly advocate the barcoding approach as a valuable new technology
available to the horticulture industry to help correct plant identification errors
in the international trade.
