Subtitle of news article in Nature, February 2014Prologue
Over the past decade, the various potential practical benefits offered by DNA ‘barcoding’ have been rehearsed ad nauseam, typically with at least modest exaggeration. However, definitions of barcoding, most of which remain rooted in the already passé holy grail of identifying the perfect genic region to characterize (and thereby identify) all life, have failed to keep pace with developments in sequencing technology. Solid-state desktop sequencers are becoming de rigueur in molecular laboratories, and palmtop sequencers are literally undergoing field trials – albeit field trials that are proving disappointingly protracted. Discussion of the implications of the eventual (hopefully imminent) widespread availability of such pocket sequencers has been extraordinarily limited and unidirectional, focusing on the advances that technologists can offer likely professional users, notably field ecologists. But even less consideration has been given to the converse flow of information – specifically, the immense benefits that field biologists could feed into today's ailing global taxonomic enterprise. We have also ignored the likely consequences of the literal deluge of DNA sequences and associated data that will be generated by the overlooked majority of users of such devices who will be ‘non-professionals’, notably students and enthusiastic amateur natural historians.
The ideal palmtop device will not only gather DNA sequences from appropriate barcoding regions but will also record fixed-scale images of the material taken prior to analysis, together with metre-accuracy GPS coordinates. The palmtop will communicate instantly via satellite with major DNA and image databases, providing the field analyst with a hierarchy of likely identifications while s/he is still present at the field locality. If correctly organized and populated with accurate data, both molecular and morphological, core databases such as GenBank could also assess the potential scientific interest of the analysed material, and when appropriate, request immediate acquisition of morphological and/or molecular vouchers for subsequent deposition in major natural history collections.
