“…Authors of these sequences state that DNA was extracted from adductor muscle (Ni et al. ). It is well known that some degree of heteroplasmy is commonly found in the soma of male individuals of DUI species (Zouros ; and references therein) and cases of M mtDNA leakage in female soma have been also reported (Ghiselli et al.…”

Although mitochondrial inheritance in metazoans is typically strictly maternal, doubly uniparental inheritance (DUI) is probably the major exception to this widespread rule. DUI has been found in many species of bivalve molluscs, belonging to several different families. Based on current understanding, the detection of DUI generally relies on the detection of two distinct mitochondrial DNA lineages: a female-transmitted one, that dominates somatic tissues in males and females and eggs, and a male-transmitted one, that dominates the male germline and sperm. When a new species with DUI is identified, novel data are available to make a better inference on the evolution of this phenomenon within the Bivalvia. In this study, mitochondrial heteroplasmy in Pseudocardium sachalinense (Schrenck, 1862) is described. This species belongs to the family of Mactridae, in which DUI has not been previously demonstrated: this finding allowed to upgrade the present knowledge about the distribution of DUI.

“…Traditional DNA barcoding calculates intra‐/interspecific genetic distances and constructs neighbor‐joining (NJ) tree for species delimitation. The clustered clades in a phylogenetic tree and the existence of the barcoding gap are interpreted as distinct species (Ni, Li, Kong, Huang, & Li, ). In addition to traditional barcoding analysis (NJ analysis), generalized mixed Yule‐Coalescent (GMYC) is also a popular approach for species identification based on single‐locus data, which estimates species boundaries from branching rates in a phylogenic tree (Fujisawa & Barraclough, ).…”

The American cockroach (Periplaneta americana) is a globally invasive pest that can cause significant economic loss and threaten human health. Although it is abundant and lives in close proximity to humans, few studies have investigated the genetic diversity of P. americana. Our study analyzed 1,053 P. americana and other Periplaneta species' samples from different locations in China and the United States. A traditional tree‐based method using 17 unique mitochondrial COI haplotypes of P. americana and 20 haplotypes of the other Periplaneta species accurately identified P. americana with a barcoding threshold of 5.1%. To identify the population genetic structure of P. americana, we investigated wingless gene and pooled them with obtained mtDNA data for a combined analysis. Although the genetic diversity of the USA group was relatively higher than the China group, the number of haplotypes and alleles of both groups was small. The analysis of molecular variance (AMOVA), intraspecific phylogeny, and haplotype networks indicated that P. americana had very little global genetic differentiation. The weak geographic genetic structure might reflect the human‐mediated dispersal of P. americana. Despite no apparent phylogeographic assignment of mtDNA and nuclear lineages was observed in both BI trees, the integrated COI sequence data identified four distinct P. americana haplotype groups, showing four ancient maternal lineages of P. americana in China and the United States.

Separation in flowering time contributes to the maintenance of sympatric cryptic plant lineages

Sympatric cryptic lineages are a challenge for the understanding of species coexistence and lineage diversification as well as for management, conservation, and utilization of plant genetic resources. In higher plants studies providing insights into the mechanisms creating and maintaining sympatric cryptic lineages are rare. Here, using microsatellites and chloroplast sequence data, morphometric analyses, and phenological observations, we ask whether sympatrically coexisting lineages in the common wetland plant Juncus effusus are ecologically differentiated and reproductively isolated. Our results show two genetically highly differentiated, homoploid lineages within J. effusus that are morphologically cryptic and have similar preference for soil moisture content. However, flowering time differed significantly between the lineages contributing to reproductive isolation and the maintenance of these lineages. Furthermore, the later flowering lineage suffered less from predispersal seed predation by a Coleophora moth species. Still, we detected viable and reproducing hybrids between both lineages and the earlier flowering lineage and J. conglomeratus, a coexisting close relative. Flowering time differentiation between the lineages can be explained by neutral divergence alone and together with a lack of postzygotic isolation mechanisms; the sympatric coexistence of these lineages is most likely the result of an allopatric origin with secondary contact.
