Protein-tyrosine kinases play pivotal roles in cell signal transduction. We have isolated a cDNA clone encoding a novel human intracytoplasmic tyrosine kinase, termed matk (megakaryocyte-associated tyrosine kinase). Expression of matk mRNA was predominantly found in cells of megakaryocytic lineage. The matk cDNA clone encodes a polypeptide of 527 amino acids and has closest sequence similarity ...

Abstract The aim of DNA barcoding is to enable fast and accurate species identification. However, universal plant barcodes often do not provide species-level discrimination, especially in taxonomically complex groups. Here we use Lauraceae for the design evaluation strategies, considering: (1) efficacy taxon-specific barcode regions compared with discrimination; (2) how extent intra- interspeci...

A DNA barcode is a DNA fragment used to identify species. For land plants, DNA fragments of plastid genome could be the primary consideration. Unfortunately, most of the plastid candidate barcodes lack species-level resolution. The identification of DNA barcodes of high resolution at species level is critical to the success of DNA barcoding in plants. We searched the available plastid genomes f...

Caryophyllaceae is a large angiosperm family, with many species being utilized as ornamental or medicinal plants in Korea, addition to several endangered that are managed by the government. In this study, we used DNA barcoding for accurate identification of Korean Caryophyllaceae. A total 78 taxa (n = 215) were sequenced based on three chloroplast regions (rbcL, matK, and psbA–trnH) nuclear rib...

Dryopteris blanfordii (C.Hope) C.Chr. is a member of the Dryopteridaceae, growing in high altitude Picea or Abies forests (2900-3500 m) in China and India. Phylogenetic relationships between D. blanfordii subsp. nigrosquamosa and closely related species of Dryopteris were investigated using a combined analysis of multiple molecular data sets (the protein-coding region of rbcL and matK genes and...

The genus Stachys is one of the largest in Lamiaceae family. Representatives are among most ancient medicinal plants used ethnomedicine. Balkan endemic species S. thracica , bulgarica and scardica included Red Data Book Bulgaria due to their endangered status scarcely studied. aim present work was examine genetic these three during process ex situ conservation. To gain information about taxonom...

Tripterygium wilfordii (Celastraceae) is a traditional Chinese medicine; and the dried root and rhizome constitute the main officinal parts. Tripterygium wilfordii has been identified as a potential candidate for the treatment of systemic lupus erythematosus, rheumatoid arthritis, nephritis, asthma, leprosy, and cancer. The phylogenetic relationships within the Tripterygium genus are ambiguous;...
