Yubari in Hokkaido, Japan and it has been proposed as an immediate hybrid derived from two species of the same section Bronchiales based on morphological intermediacy: namely S. nishidae, a diploid species endemic to a nearby cliff composed of greenschist and tetraploid S. rebunshirensis comparatively broadly distributed in Japan and Russian Far East. Saxifraga yuparensis is red-listed and it is crucial for conservation planning to clarify whether this is an immediate hybrid and lacks a unique gene pool. The immediate-hybrid hypothesis was tested by molecular and cytological data. In nuclear ribosomal and chloroplast DNA trees based on maximum parsimony and Bayesian criteria, S. yuparensis and S. rebunshirensis formed a clade with several other congeners while S. nishidae formed another distinct clade. Genome-wide SNP data clearly separated these three species in principal coordinate space, placing S. yuparensis not in-between of S. rebunshirensis and S. nishidae. Chromosome observation indicated that S. yuparensis is tetraploid, not triploid directly derived from diploid-tetraploid crossing. Additionally, observation of herbarium specimens revealed that leaf apex shape of S. yuparensis fell within the variation of S. rebunshirensis. These results indicate that S. yuparensis is not an immediate hybrid of S. rebunshirensis and S. nishidae but a distinct lineage and an extremely narrow endemic species, that deserves for intensive conservation.

Abstract Recent studies on paleogenomics have reported some Paleolithic and Neolithic genomes that have provided new insights into the human population history in East and Northeast Asia. However, there remain some cases where more recent migration events need to be examined to elucidate the detailed formation process of local populations. Although the area around northern Japan is one of the regions archaeologically suggested to have been affected by migration waves after the Neolithic period, the genetic source of these migrations are still unclear. Thus, genomic data from such past migrant populations would be highly informative to clarify the detailed formation process of local populations in this region. Here, we report the genome sequence of a 900-year-old adult female (NAT002) belonging to the prehistoric Okhotsk people, who have been considered to be the past migrants to northern Japan after the Neolithic period. We found a close relationship between NAT002 and modern Lower Amur populations and past admixture events between the Amur, Jomon, and Kamchatka ancestries. The admixture dating suggested migration of Amur-related ancestry at approximately 1,600 BP, which is compatible with the archaeological evidence regarding the settlement of the Okhotsk people. Our results also imply migration of Kamchatka-related ancestry at approximately 2,000 BP. In addition, human leukocyte antigen (HLA) typing detected the HLA-B*40 allele, which is reported to increase the risk of arthritis, suggesting the genetic vulnerability of NAT002 to hyperostosis, which was observed around her chest clavicle.

Wagnerinus frugivorus sp. nov. (Ceutorhynchinae: Ceutorhynchini) is described from Hokkaido, northern Japan, based on morphological and biological characters. Morphologically, this new species closely resembles Wagnerinus carinulatus (Faust) from the Russian Far East and W. costatus (Hustache) from Japan and Korea in having an emarginate anterior margin of the rostrum, sternite VIII diminished to a pair of small sclerites, and longitudinal rows of endophallic sclerites. However, it is distinctive enough to be distinguished from W. carinulatus and W. costatus mainly by the more conspicuous mucrones of mid and hind tibiae, deeper concavities of ventrites I and II, and larger paired prominences of ventrite V. Also, W. frugivorus clearly differs from W. costatus in terms of host plant utilization, the former feeds on the seed capsules of Weigela middendorffiana (Caprifoliaceae) as larvae, while the latter utilizes midge galls on the axillary buds of Weigela species. In addition to general taxonomic information, we provide a 1366-bp fragment of the mitochondrial cytochrome oxidase subunit I gene from the holotype as a DNA barcode of W. frugivorus and discuss the importance of DNA barcoding combined with species descriptions.

The aim of the study was to compare the variability of the composition, chemical identity and content of biologically active phenolic compounds in the fruits and leaves of the blue honeysuckle (Lonicera subsection Caeruleae) plants of different environmental and geographic provenances, sampled from the introduction plantation station in the forest steppe zone near the Ob River (Novosibirsk, Russia). In extracts from the leaves 25 individual compounds representing various polyphenolic classes were identified using HPLC-MS technique; seven of the compounds were identified as hydroxycinnamic acids, five compounds were flavonols, and eight compounds represented flavones. The maximal number of individual compounds was present in samples of the Altai subspecies of the tetraploid species L. caerulea subsp. altaica, whereas the minimal number was detected in samples of L. boczkarnikowae, a diploid species from the Russian Far East (Primorsky region). The lowest total polyphenolics content (6,260 mg/100 g of air-dry phytomass) was found in samples of L. caeruleae subsp. pallasii, whereas the content in samples from other blue honeysuckle subspecies ranged within 11.620-14.030 mg/100 g of air-dry phytomass. High content of flavones in extracts from leaves, always exceeding the flavonol content, was found to be a characteristic feature of L. caerulea subsp. altaica. Among L. сaerulea subspecies, L. сaerulea subsp. pallasii was shown to have the largest ratio of flavonols to flavones. L. boczkarnikowae also had high content of flavonols, significantly exceeding the flavones content in the plants organs. The main component of anthocyanins was cyanidin-3-glucoside, accounting for up to 91%. The fruits of L. caerulea subsp. altaica, L. сaerulea subsp. venulosa and L. boczkarnikowae had the highest anthocyanin content, ranging 2.950–3.200 mg/100 g air-dry phytomass, whereas the fruits of L. сaerulea subsp. pallasii had the lowest one (1,573 mg/100g). Extracts from the leaves were found to have significantly higher polyphenolics content as compared to the ones from the fruits; thus the leaves can be recommended as a prospective medicinal source.

AbstractEuropean forests are experiencing extensive invasion from the Ash pathogen Hymenoscyphus fraxineus, an ecological niche competitor to the non-pathogenic native congener H. albidus. We report the genome-wide diversity and population structure in Asia (native) and Europe (the introduced range). We show H. fraxineus underwent a dramatic bottleneck upon introduction to Europe around 30-40 generations ago, leaving a genomic signature, characterized by long segments of fixation, interspersed with “diversity islands” that are identical throughout Europe. This means no effective secondary contact with other populations has occurred. Genome-wide variation is consistently high within sampled locations in Japan and the Russian Far East, and lack of differentiation amongst Russian locations suggests extensive gene flow, similar to Europe. A local ancestry analysis supports Russia as a more likely source population than Japan. Negligible latency, rapid host-range expansion and viability of small founding populations specify strong biosecurity forewarnings against new introductions from outside Europe.

Lime Leafminer

Historical herbaria are valuable sources of data in invasion biology. Here we study the invasion history of the lime leafminer, Phyllonorycter issikii, by surveying over 15 thousand herbarium specimens of limes (Tilia spp.) collected in the Palearctic during last 253 years (1764-2016). The majority of herbarium specimens with the pest mines (89%) originated from East Asia (1859-2015), whereas remaining 11% of specimens with the mines came from Europe, European Russia and Western Siberia (1987-2015). These results support the hypothesis of a recent Ph. issikii invasion from Eastern to Western Palearctic. Single molecule real-time sequencing of the COI barcode region of 93 archival larvae and pupae (7-162 years old) dissected from the mines on historical herbaria allowed to distinguish between Ph. issikii and Ph. messaniella, a polyphagous species rarely feeding on Tilia, which mines were found in herbarium from Europe dated by 1915-1942. We discovered 25 haplotypes of Ph. issikii, of which 16 haplotypes were present solely in East Asia, and revealed wide distribution of the species in China. Six haplotypes shared between Eastern and Western Palearctic suggest the contribution of Ph. issikii populations from the Russian Far East, China and Japan to the westward invasion.
