The matK gene is named according to its possible maturase function and its location within the trnK gene encoding the tRNA (UUU). A 509 open reading frame was found to reside in an intron when the trnK gene was sequenced in tobacco (Nicotiana tabacum) (Sugita et al., 1985). Later, a complete sequence of the liverwort Marchantia polymorpha confirmed the existence of this open reading frame in th...

All higher plant plastid genomes have six classes of tRNA genes containing introns. One of those is the tRNALysUUU gene, which encodes maturase protein. In the case of liverwort species from the genus Porella and mosses from the genus Plagiomnium, the maturase coding gene (matK) represents a truncated form of other plant matK genes: several subdomains of the reverse transcriptase-like domain an...

Homalium glandulosum Tagane & V. H. Nguyen, from Vu Quang National Park in northern Vietnam, is newly described. This species is characterized by distinct glands, often stalked, at the base of the lamina and along the margin of the stipules and bracteoles. Illustrations, DNA barcodes of the two regions of rbcL and matK, and a key to the species of Homalium in Vietnam are also provided.

this study included 81 samples which belonged to 13 speices from myriophyllum genus. both nrdna its1 and its2 and cpdna matk, rbcl and trnh-psba loci were used for diagnose of invasive from native plant. the nrdna its1and its2 data proved highly variable and could differentiate between all but had low pcr amplification success,based on these result they would not recommend as a suitable barcode...

Ocotea species present economic importance and biological activities attributed to their essential oils (EOs) and extracts. For this reason, various strategies have been developed for their conservation. The chemical compositions of the essential oils and matK DNA sequences of O. caudata, O. cujumary, and O. caniculata were subjected to comparison with data from O. floribunda, O. veraguensis, a...

Phylogenetic relationships were examined within the "higher" Hamamelididae using 21 species representing eight families and related outgroups. Chloroplast DNA sequences encoding the matK gene (/1 kilobase) provided 258 informative nucleotide sites. Phylogenetic analysis of this variation produced one most parsimonious tree supporting three monophyletic groups. In this tree, Nothofagus was basal...

Polygalaceae is a large family with cosmopolitan distribution, comprising ca. 1,200 species in 27 genera. However, similar to many plant groups, the identification of mostly depends on floral and fruit characteristics; therefore, DNA barcoding could easily warrant corect sterile material. In current study, utility six widely employed barcode loci, namely rbcL, matK, trnL-F region (including trn...

BACKGROUND Widespread uptake of DNA barcoding technology for vascular plants has been slow due to the relatively poor resolution of species discrimination (∼70%) and low sequencing and amplification success of one of the two official barcoding loci, matK. Studies to date have mostly focused on finding a solution to these intrinsic limitations of the markers, rather than posing questions that ca...
