Six American eels Anguilla rostrata were identified in the Kaoping River of south-western Taiwan by sequencing the mitochondrial cytochrome b gene ( mtCyt-b ). This was the first record of an exotic eel species in the natural waters of Taiwan. The exotic eels may have been imported from North America at the elver stage for aquaculture and escaped from culture ponds. 相似文献

The mitochondrial DNA sequence of cytochrome b gene in a Thoroughbred horse was determined. By comparing DNA sequences between the Thoroughbred and published sequence data (two horses and one Grevyi zebra), polymerase chain reaction (PCR) primers were designed for amplification of a 590 bp DNA fragment in the cytochrome b gene, and PCR-restriction fragment length polymorphism (RFLP) analysis was studied in 140 horses of six breeds using three restriction enzymes ( AciI, BamHI, RsaI ). Two morphs were found using each of the three enzymes. By combining three enzymes morphs, the 140 horses examined were classified into four types. Type 2 was most frequent in all breeds. 相似文献

A molecular approach, polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP), was developed to identify the planktonic larvae of Cynoscion species. Species-specific mitochondrial DNA markers were developed using three restriction endonucleases ( Dde I, Hae III and Hin fI). These markers permitted the accurate discrimination of the five Cynoscion species in the Bay of Panama. 相似文献

白腹锦鸡和红腹锦鸡的遗传分化 总被引：24，自引：3，他引：24
白腹锦鸡Chrysolophus amherstiae (Leadbeater)和红腹锦鸡Chrysolophus pictus (L.)是两个种还是两个亚种尚有争议。测定了白腹锦鸡C.amherstiae两个个体部分细胞色素b基因序列,得到完全相同的861bp的序列。与红腹锦鸡C.pictus的同源序列相比,在21个位点上出现变异,应用木村资生的双参数法算出两者的遗传距离为2.5％。根据鸡形目细胞色素b基因核苷酸替换的速率约为每百万年0.5％～ 0.7％,推断出两种锦鸡的分化时间至少为1.7百万年。从而在分子水平上支持白腹锦鸡(C.amherstiae)和红腹锦鸡(C.pictus)是两个独立种。 Abstract：It was disputed that Chrysolophus amherstiae (Leadbeater) and Chrysolophus pictus (L.) were two species or two subspecies.DNA sequences spanning 861 nucleotide bases of the mitochondrial cytochrome-b gene were reported in two C.amherstiae.21 sites were different compared with C.pictus's homologous sequences. Genetic distance between C.amherstiae and was 2.5％ based on the Kimura's two parameter's methods.The divergence time between C.amherstiae and C.pictus was at least 1.7My based on the substitution rate of nucleotide acid of cytothrome-b gene in Galliformes.We suggested that Chrysolophus amherstiae and Chrysolophus pictus are two distinct species. 相似文献

The adult head of the Hessian fly Mayetiola destructor was examined and described in detail. Morphological features are evaluated with respect to phylogenetic implications and possible effects of miniaturisation. Preserved groundplan features of Diptera are the orthognathous orientation of the head, the vestiture of small microtrichia (possible autapomorphy), filiform antennae inserted frontally between the compound eyes, the presence of a clypeolabral muscle (possible autapomorphy), the presence of labellae (autapomorphy), and the presence of only one premental retractor. Potential synapomorphies of the groups assigned to Bibionomorpha are the origin of M. tentorioscapalis medialis on the frons and the loss of M. craniolacinialis. Further apomorphies of Cecidomyiidae identified in Mayetiola are the unusually massive anterior tentorial arm, the absence of the labro‐epipharyngeal food channel, the absence of the lacinia, and the presence of antennal sensilla connected by a seta, a feature not known from any other group of Diptera. The very large size of the compound eyes (in relation to the entire head surface) and the complete loss of ocelli are possible effects of miniaturization. The large size of the brain (in relation to the cephalic lumen), the unusual shape of the optic lobes, and the absence of the frontal ganglion as a separate structure are probably also linked with size reduction.

In this study, thirty-six individuals of Acheilognathus macropterus were collected from the Heilongjiang River,the Yangtze River,and the Nandujiang River.Partial mitochondrial cytochrome b gene region (636 base pair) was sequenced to these samples and 22 haplotypes were found.With A.chankaensis and A.tokinensis as outgroups,their relationships were analyzed.The p-distances were calculated with Mega software and a molecular phyiogenetic tree was constructed using the neighbor-joining (NJ) method.The proportions of main morphological characters were compared as well.P-distances showed that the genetic differences in A.macropterus samples were far smaller than those between these samples and the outgroups.The molecular phylogenetic tree shows that samples with barbels and those without barbels were intermingled.There was no distinctive difference in proportions of morphological characteristics among them.These results suggested that samples with barbels and those without barbels (formally identified as A.taenianalis) are the same species;A.taenianalis is synonymous with A.macropterus.The thirtysix individuals were grouped into five clades and the positions of the samples in the clades were correspondingly grouped within their geographical distributions.Among the five clades,clades 1 and 5 included samples from the Heilongjiang River and Nandujiang River respectively.The samples from the Yangtze River scattered into clades 2,3,and 4.There were distinctive genetic differences (> 5%)among them.Interestingly,the distributions of the 21 samples in these three clades were not correlated to their geographical distributions.It is postulated that these genetic differences were due to the bitterlings' mating choice mechanism,the prozygotic isolation.The genetic differences between the fish from Nandujiang River and those from the mainland indicated that they were separated early.However,the small genetic differences among the samples and the positions of the fish from the Heilonjiang River in the molecular phylogenetic tree indicate that fish in Heilongjiang River might have dispersed from the Yangtze River to that area much later. 相似文献

Mitochondrial DNA introgression from Lepus timidus into Lepus granatensis and Lepus europaeus was recently reported in Iberia, although L. timidus presumably retreated from this region at the end of the last ice age. Here we assess the extent of this ancient mtDNA introgression by RFLP analysis of 695 specimens representing the three hare species present in Iberia. The introgressed L. timidus lineage was found in 23 of the 37 populations sampled. It is almost fixed in L. europaeus across its Iberian range in the Pyrenean foothills, and in L. granatensis, which occupies the rest of the peninsula, it is predominant in the north and gradually disappears further south. We also found it in Lepus castroviejoi, a species endemic to Cantabria. Multiple hybridizations and, potentially, a selective advantage for the L. timidus lineage can explain the remarkable taxonomic and geographical range of this mitochondrial introgression. 相似文献
