根损线虫(Pratylenchusspp.)的可靠和准确鉴定是确定其对作物产量的潜在威胁,从而制定有效的农艺管理策略的必要步骤。人们认识到,基于dna的技术可以快速鉴定一系列植物寄生线虫,包括pratylenchusspp。高效和可重复的DNA提取是分子方法的核心。本文比较了六种常见的DNA提取方法,评估了它们获得高质量外突扇尾蚊DNA样本的效率。样本有5个和10个p。所有测试的提取方法都能成功地提取和扩增透线虫,而单个线虫的样本在DNA扩增方面存在挑战。在所有测试的方法中,玻璃珠DNA提取方案被证明是有效的。pentransand和所有其他测试物种(P. crenatus,P.;neglectusandP。thornei),以相对较低的成本和快速的样品通量产生高质量的DNA。
Robust and accurate identification of root-lesion nematodes (Pratylenchusspp.) is an essential step for determining their potential threat to crop yields and, consequently, development of an efficient agronomic management strategy. It is recognised that DNA-based techniques provide rapid identification of a range of plant-parasitic nematodes includingPratylenchusspp. Efficient and repeatable DNA extraction is central to molecular methodologies. Here, six common DNA extraction protocols were compared to evaluate their efficiency to obtain quality DNA samples forPratylenchus penetrans. Samples with five and ten individuals ofP. penetranswere successfully extracted and amplified by all extraction methods tested, whereas samples with a single nematode presented challenges for DNA amplification. Among all methods tested, the DNA extraction protocol with glass beads proved to be efficient forP. penetransand all other species tested (P. crenatus,P. neglectusandP. thornei), generating high quality DNA at comparatively low cost and with a rapid sample throughput.
