基于线粒体16S rRNA基因序列对3种珍珠贝的鉴定
Species identification of threePteriaspecies based on mito-chondrial 16S rRNA gene
摘要
Abstract
Species identification based on morphology highly relies on the ability of taxonomists. Some species can be easily misidentified based on morphological characteristics alone. To improve the accuracy of species identifica-tion, threePteriaspecies sampled from Weizhou Island, Guangxi, were identified based on shell morphology and mitochondrial 16S rRNA gene sequences. These three species were identified asP. penguin,P. loveni andP. chinensis, respectively, based on shell morphology. However, the specimen that was identified asP. loveni based on morphological characteristicswas later identified asP. lata using 16S rRNA gene sequences.P. loveniandP. lata are two distinct species and are not synonyms. The genetic distances are much higher between species than within species, indicating that 16S rRNA gene is useful for species identification in the genusPteria.P. latais a valid species, andP. loveniexists in China, with no further confirmation required.关键词
