Species identification of medicinal pteridophytes by a DNA barcode marker, the chloroplast psbA-trnH intergenic region.
Medicinal pteridophytes are an important group used in traditional Chinese medicine; however, there is no simple and universal way to differentiate various species of this group by morphological traits. A novel technology termed "DNA barcoding" could discriminate species by a standard DNA sequence with universal primers and sufficient variation. To determine whether DNA barcoding would be effec...
متن کاملAn introduction to freshwater aquarium plants
Freshwater aquarium plants are one of the most popular components in freshwater aquariums. The aquarium plant trade is a lucrative trade in its producer countries. In fact, the aquarium is a closed and controlled environment that coordination between all its components is necessary to maintain the balance and stability of this small ecosystem. They beautify the interior of the aquarium, moreove...
متن کاملEfficient distinction of invasive aquatic plant species from non-invasive related species using DNA barcoding.
Biological invasions are regarded as threats to global biodiversity. Among invasive aliens, a number of plant species belonging to the genera Myriophyllum, Ludwigia and Cabomba, and to the Hydrocharitaceae family pose a particular ecological threat to water bodies. Therefore, one would try to prevent them from entering a country. However, many related species are commercially traded, and distin...
متن کاملA Two-Locus Global DNA Barcode for Land Plants: The Coding rbcL Gene Complements the Non-Coding trnH-psbA Spacer Region
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 plants has been limited by intrinsically lower rates of sequence evolution in plant genomes than that observed in animals. This low rate has complicated the trade-off in finding a locus that is universal a...
متن کاملIntraspecific Inversions Pose a Challenge for the trnH-psbA Plant DNA Barcode
BACKGROUND The chloroplast trnH-psbA spacer region has been proposed as a prime candidate for use in DNA barcoding of plants because of its high substitution rate. However, frequent inversions associated with palindromic sequences within this region have been found in multiple lineages of Angiosperms and may complicate its use as a barcode, especially if they occur within species. METHODOLOGY...
