Distribution, Morphological Variations and cpDNA PCR-RFLP Analysis of Dendranthema yoshinaganthum.

Molecular identification of Sinopodophyllum hexandrum and Dysosma species using cpDNA sequences and PCR-RFLP markers.

Rhizomes of Sinopodophyllum hexandrum and Dysosma species, which have long been used in the traditional Chinese herbal medicine, have similar morphology and chemical composition. However, the podophyllotoxin content is higher in the rhizomes of S. hexandrum than in those of Dysosma species. The PCR-amplified fragments of trnT -trnL showed length variation between S. hexandrum and Dysosma specie...

PCR and RFLP Analysis for Identification and Typing of Helicobacter pylori Strains from Gastric Biopsy Specimens

Identification of gadoid species (Pisces, Gadidae) by PCR-RFLP analysis.

A rapid PCR-RFLP analysis was optimized to identify the presence of 3 closely related gadoid fish species: Alaska pollack Theragra chalcogramma, Pacific cod Gadus macrocephalus and Atlantic cod Gadus morhua in commercial seafood products. Gadoid universal primers were designed for PCR amplification of a 558-bp fragment encoding the mitochondrial cytochrome b gene. Without purification of the PC...
