The fish family Dussumieriidae (suborder Clupeoidei), commonly called round herrings, is traditionally considered to be a key taxon for understanding the evolution of the Clupeoidei because some of its morphological characteristics have been interpreted as being either derived or primitive, such as the nearly complete absence of abdominal scutes. Recent molecule-based studies showed that the Dussumieriidae...
We present the first study to use whole mitochondrial genome sequences to examine phylogenetic affinities of the flatfishes (Pleuronectiformes). Flatfishes have attracted attention in evolutionary biology since the early history of the field because understanding the evolutionary history and patterns of diversification of the group will shed light on the evolution of novel body plans. Because recent...
After the completion of several entire genome projects and a remarkable increase in public genetic databases in the recent years the results of post-genomic analyses can facilitate a better understanding of the genomic evolution underlying the diversity of organisms and the complexity of gene function. This influx of genomic information and resources is also beneficial to the discipline of systematic...
Occurrence of chimeric sequences and related artifacts in PCR cloning procedures gives us risks of over-estimation of haplotypes or alleles. Recombination among haplotypes occurs through template switching during PCR cycles or through random repair of mismatch sites on heteroduplex DNA by the host cell. To eliminate the chimeric cloning artifacts, we tested two alternative protocols using T7 endonuclease...
