Use of DNA barcodes to identify flowering plants.
Comparison of the total plastid genomes of tobacco and deadly nightshade enhanced with trials on widely divergent angiosperm taxa suggest that the sequences in this pair of loci have the potential to discriminate among the largest number of plant species for barcoding purposes. Expand
Angiosperm phylogeny inferred from 18S rDNA, rbcL, and atpB sequences
A phylogenetic analysis of a combined data set for 560 angiosperms and seven outgroups based on three genes, 18S rDNA, rbcL, and atpB representing a total of 4733 bp is presented, resulting in the most highly resolved and strongly supported topology yet obtained for angiosPerms. Expand
A DNA barcode for land plants
The 2-locus combination of rbcL+matK will provide a universal framework for the routine use of DNA sequence data to identify specimens and contribute toward the discovery of overlooked species of land plants. Expand
Leafsnap: A Computer Vision System for Automatic Plant Species Identification
The first mobile app for identifying plant species using automatic visual recognition from photographs of their leaves is described, which obtains state-of-the-art performance on the real-world images from the new Leafsnap Dataset --- the largest of its kind. Expand
A Two-Locus Global DNA Barcode for Land Plants: The Coding rbcL Gene Complements the Non-Coding trnH-psbA Spacer Region
A combination of the non-coding trnH-psbA spacer region and a portion of the coding rbcL gene is recommended as a two-locus global land plant barcode that provides the necessary universality and species discrimination. Expand
Plant DNA barcodes and a community phylogeny of a tropical forest dynamics plot in Panama
It is demonstrated that a three-locus DNA barcode when applied to 296 species of woody trees, shrubs, and palms found within the 50-ha Forest Dynamics Plot on Barro Colorado Island, Panama, resulted in >98% correct identifications. Expand
The phylogeny and a new classification of the gingers (Zingiberaceae): evidence from molecular data.
New phylogenetic analyses based on DNA sequences of the nuclear internal transcribed spacer (ITS) and plastid matK regions suggest that at least some of these morphological traits are homoplasious and three of the tribes are paraphyletic. Expand
Medical Archives and Manuscripts News, 2005
Background. A useful DNA barcode requires sufficient sequence variation to distinguish between species and ease of application across a broad range of taxa. Discovery of a DNA barcode for land plantsExpand
The evolution of bat pollination: a phylogenetic perspective.
It is proposed that flower-visiting bats provide two important benefits to plants: they deposit large amounts of pollen and a variety of pollen genotypes on plant stigmas and, compared with many other pollinators, they are long-distance pollen dispersers. Expand
