Molecular characterisation of plant parasitic nematode Longidorus poessneckensis Altherr, 1974 (Nematoda: Longidoridae)

Molecular characterisation of plant parasitic nematode Longidorus poessneckensis Altherr, 1974... The plant parasitic nematode Longidorus poessneckensis found in Austria, the Czech Republic, Germany, Poland and the Slovak Republic was molecularly characterized. Mitochondrial genes encoding cytochrome c oxidase subunit I (COI) and nicotinamide dehydrogenase subunit 4 (nad4), the D2 and D3 expansion segments of 28S rRNA and Internal transcribed spacer 1 (ITS1) rRNA were sequenced for 16 L. poessneckensis populations. Six haplotypes of COI and five haplotypes of nad4 were determined. Nucleotide intraspecific variation was up to 17.1% for the partial sequenced COI gene and up to 17.7% for the partial sequenced nad4 gene, the latter being the highest up to date known intraspecific variation in this genus. The analyses of multiple amino acid sequence alignments of mitochondrial genes revealed low variability (0–2.4%) for COI gene and high divergence (0–7.6%) for nad4 gene. Intraspecific sequence diversity for the D2-D3 of 28S rRNA gene was up to 1.2% and for ITS1 rRNA gene was up to 1.6%. It has been hypothesized, that during the Last Glacial Maximum, L. poessneckensis populations probably persisted in refuge areas in the Carpathian Mountains and subsequently expanding from these areas and colonizing other European regions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png European Journal of Plant Pathology Springer Journals

Abstract

The plant parasitic nematode Longidorus poessneckensis found in Austria, the Czech Republic, Germany, Poland and the Slovak Republic was molecularly characterized. Mitochondrial genes encoding cytochrome c oxidase subunit I (COI) and nicotinamide dehydrogenase subunit 4 (nad4), the D2 and D3 expansion segments of 28S rRNA and Internal transcribed spacer 1 (ITS1) rRNA were sequenced for 16 L. poessneckensis populations. Six haplotypes of COI and five haplotypes of nad4 were determined. Nucleotide intraspecific variation was up to 17.1% for the partial sequenced COI gene and up to 17.7% for the partial sequenced nad4 gene, the latter being the highest up to date known intraspecific variation in this genus. The analyses of multiple amino acid sequence alignments of mitochondrial genes revealed low variability (0–2.4%) for COI gene and high divergence (0–7.6%) for nad4 gene. Intraspecific sequence diversity for the D2-D3 of 28S rRNA gene was up to 1.2% and for ITS1 rRNA gene was up to 1.6%. It has been hypothesized, that during the Last Glacial Maximum, L. poessneckensis populations probably persisted in refuge areas in the Carpathian Mountains and subsequently expanding from these areas and colonizing other European regions.
