A duplicate gene rooting of seed plants and the phylogenetic position of flowering plants.
Flowering plants represent the most significant branch in the tree of land plants, with respect to the number of extant species, their impact on the shaping of modern ecosystems and their economic importance. However, unlike so many persistent phylogenetic problems that have yielded to insights from DNA sequence data, the mystery surrounding the origin of angiosperms has deepened with the adven...

متن کاملRefining the DNA barcode for land plants.
T he goal of DNA barcoding is conceptually simple: Find one or a few regions of DNA that will distinguish among the majority of the world’s species, and sequence these from diverse sample sets to produce a large-scale reference library of life on earth (1). This approach can then be used as a tool for species identification and to help in the discovery of new species (2). Since the first DNA ba...
متن کاملDNA barcoding methods for land plants.
DNA barcoding in the land plants presents a number of challenges compared to DNA barcoding in many animal clades. The CO1 animal DNA barcode is not effective for plants. Plant species hybridize frequently, and there are many cases of recent speciation via mechanisms, such as polyploidy and breeding system transitions. Additionally, there are many life-history trait combinations, which combine t...
متن کاملA DNA barcode for land plants.
DNA barcoding involves sequencing a standard region of DNA as a tool for species identification. However, there has been no agreement on which region(s) should be used for barcoding land plants. To provide a community recommendation on a standard plant barcode, we have compared the performance of 7 leading candidate plastid DNA regions (atpF-atpH spacer, matK gene, rbcL gene, rpoB gene, rpoC1 g...
