The phylogenetic position of Myxobolus carnaticus (Myxozoa, Myxosporea, Bivalvulida) infecting gill lamellae of Cirrhinus mrigala (Hamilton, 1822) based on 18S rRNA sequence analysis
Myxozoans are an economically important group of microscopic parasites best known for the diseases they cause in commercially important fish hosts. The classification of myxosporeans is generally based on the morphology of their myxospores. Without molecular data, it is very difficult to identify new or existing species. DNA sequence information is therefore, a prerequisite to taxonomic and phy...
متن کاملPhylogenetic analysis of Lymnaeid snails based on 18S rDNA sequences.
The 18S rDNA sequences of the six most common European Lymnaeidae species (Mollusca:Gastropoda:Basommatophora) have been obtained by direct PCR cycle sequencing and silver staining methods. The sequence alignment and secondary structures of the 18S rRNA gene of Lymnaea stagnalis, L. auricularia, L. peregra, L. palustris, L. glabra, and L. truncatula are analyzed. This gene proves to be a good m...
متن کاملfrom 18S rRNA Sequences
Several families in the beetle suborder Adephaga have an aquatic life style and are commonly grouped in the “Hydradephaga,” but their monophyly is contentious and relationships between and within these families are poorly understood. Here we present fulllength 18S rRNA sequence for 84 species of Hydradephaga, including representatives of most major groups down to the tribal level, and a total o...
متن کاملPhylogenetic analysis based on 18S rRNA gene and matK gene sequences of Panax vietnamensis and five related species.
Panax vietnamensis was discovered recently in Vietnam. Its bamboo-like rhizomes, called Vietnamese Ginseng, have attracted considerable attention because of their specific pharmacological activities. In order to define the taxonomic position of this new species and include it in the molecular authentication of Ginseng drugs, the 18S ribosomal RNA gene and matK gene sequences of P. vietnamensis ...
متن کاملMolecular Identification of Polychaetes Based on 18s rRNA Gene 103 7. MOLECULAR IDENTIFICATION OF POLYCHAETES BASED ON 18S rRNA GENE
Molecular tools have revolutionized the exploration of biodiversity, especially in organisms for which traditional taxonomy is difficult (Tang et al., 2012). The small subunit (SSU) 18S rRNA gene is one of the most frequently used genes in phylogenetic studies and an important marker for random target PCR in environmental biodiversity screening. 18S rDNA is a nuclear ribosomal gene, commonly re...
