[Ab] Abstract:The number of species recognized in section Asperae of the flowering plant genus Hydrangea differs widely between subsequent revisions. This variation is largely centered around the H. aspera species complex, with numbers of recognized species varying from one to nearly a dozen. Despite indications of molecular variation in this complex, no sequence-based species delimitation methods have been employed to evaluate the primarily morphology-based species boundaries. In the present study, a multi-locus coalescent-based approach to species delimitation is employed in order to identify separate evolutionary lines within H. sect. Asperae, using four chloroplast and four nuclear molecular markers. Eight lineages were recovered within the focal group, of which five correspond with named morphotypes. The other three lineages illustrate types of conflict between molecular species delimitation and traditional morphology-based taxonomy. One molecular lineage comprises two named morphotypes, which possibly diverged recently enough to not have developed sufficient molecular divergence. A second conflict is found in H. strigosa. This morphotype is recovered as a separate lineage when occurring in geographic isolation, but when occurring in sympatry with two other morphotypes (H. aspera and H. robusta), the coalescent species delimitation lumps these taxa into a single putative species.

[Ab] Abstract:Nicotiana tabacum (Solanaceae) is the only species whose leaves can be legally marketed as tobacco according to the Japanese Tobacco Business Act. Nicotine, a major alkaloid produced by N. tabacum leaves, is regulated in pharmaceuticals by the Japanese Pharmaceutical Affairs Law. However, the use of N. tabacum stems as an excipient in pharmaceuticals is permitted, because these contained only a small amount of nicotine. Recently, several reports showed that a substantial amount of nicotine was detected in an OTC pharmaceutical product, in which N. tabacum stems were used as an excipient. Therefore, products containing N. tabacum stems could be contaminated with the leaf material. In the present study, we established a method to detect contamination of N. tabacum stem materials with its leaves, using microscopy to obtain standard reference microphotographs for identification. Cultivated N. tabacum stems and leaves, commercial cigarette leaves, and N. tabacum tissue imported as excipient material were used for preparing the microphotographs. The characteristic N. tabacum leaf structures found in the powdered fragments included: epidermal cells with sinuous anticlinal cell walls, hairs, mesophyll parenchyma with crystalized calcium oxalate (calciphytoliths), and branching vascular bundles derived from reticulate net-veins. A comparison of the microscopic characteristics of an OTC powder with those from the standard reference microphotographs was an effective method for N. tabacum stem and leaf identification. Thus, we evaluated the powdered pharmaceutical product containing N. tabacum stem tissue and Hydrangea serrata (Hydrangeaceae) leaf tissue as excipients, and confirmed the presence of N. tabacum leaf material.

[Ti] Title:Hydrangenol inhibits lipopolysaccharide-induced nitric oxide production in BV2 microglial cells by suppressing the NF-κB pathway and activating the Nrf2-mediated HO-1 pathway.

[Ab] Abstract:We previously demonstrated the anti-inflammatory effect of water extract of Hydrangea macrophylla in lipopolysaccharide (LPS)-stimulated macrophage cells. Here, we investigated whether hydrangenol, a bioactive component of H. macrophylla, attenuates the expression of nitric oxide (NO) and its associated gene, inducible NO synthase (iNOS), in LPS-stimulated BV2 microglial cells. Our data showed that low dosages of hydrangenol inhibited LPS-stimulated NO release and iNOS expression without any accompanying cytotoxicity. Hydrangenol also suppressed LPS-induced nuclear translocation of nuclear factor-κB (NF-κB) subunits, consequently inhibiting DNA-binding activity of NF-κB. Additionally, the NF-κB inhibitors, pyrrolidine dithiocarbamate (PDTC) and PS-1145, significantly attenuated LPS-induced iNOS expression, indicating that hydrangenol-induced NF-κB inhibition might be a key regulator of iNOS expression. Furthermore, our data showed that hydrangenol suppresses NO production by inducing heme oxygenase-1 (HO-1). The presence of cobalt protoporphyrin, a specific HO-1 inducer, potently suppressed LPS-induced NO production. Hydrangenol also promoted nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2) and subsequently increased its binding activity at the specific antioxidant response element sites. Additionally, transient knockdown of Nrf2 significantly downregulated hydrangenol-induced HO-1 expression, indicating that hydrangenol-induced Nrf2 is an upstream regulator of HO-1. Taken together, these data suggest that hydrangenol attenuates NO production and iNOS expression in LPS-stimulated BV2 microglial cells by inhibiting NF-κB activation and by stimulating the Nrf2-mediated HO-1 signaling pathway. Therefore, hydrangenol is a promising therapeutic agent for treatment of LPS-mediated inflammatory diseases.

[Ti] Title:A genome-scale mining strategy for recovering novel rapidly-evolving nuclear single-copy genes for addressing shallow-scale phylogenetics in Hydrangea.

[Ab] Abstract:BACKGROUND: Identifying orthologous molecular markers that potentially resolve relationships at and below species level has been a major challenge in molecular phylogenetics over the past decade. Non-coding regions of nuclear low- or single-copy markers are a vast and promising source of data providing information for shallow-scale phylogenetics. Taking advantage of public transcriptome data from the One Thousand Plant Project (1KP), we developed a genome-scale mining strategy for recovering potentially orthologous single-copy markers to address low-scale phylogenetics. Our marker design targeted the amplification of intron-rich nuclear single-copy regions from genomic DNA. As a case study we used Hydrangea section Cornidia, one of the most recently diverged lineages within Hydrangeaceae (Cornales), for comparing the performance of three of these nuclear markers to other "fast" evolving plastid markers. RESULTS: Our data mining and filtering process retrieved 73 putative nuclear single-copy genes which are potentially useful for resolving phylogenetic relationships at a range of divergence depths within Cornales. The three assessed nuclear markers showed considerably more phylogenetic signal for shallow evolutionary depths than conventional plastid markers. Phylogenetic signal in plastid markers increased less markedly towards deeper evolutionary divergences. Potential phylogenetic noise introduced by nuclear markers was lower than their respective phylogenetic signal across all evolutionary depths. In contrast, plastid markers showed higher probabilities for introducing phylogenetic noise than signal at the deepest evolutionary divergences within the tribe Hydrangeeae (Hydrangeaceae). CONCLUSIONS: While nuclear single-copy markers are highly informative for shallow evolutionary depths without introducing phylogenetic noise, plastid markers might be more appropriate for resolving deeper-level divergences such as the backbone relationships of the Hydrangeaceae family and deeper, at which non-coding parts of nuclear markers could potentially introduce noise due to elevated rates of evolution. The herein developed and demonstrated transcriptome based mining strategy has a great potential for the design of novel and highly informative nuclear markers for a range of plant groups and evolutionary scales.

[Ab] Abstract:The genus Deutzia (Hydrangeaceae), containing ca. 60 species circumscribed in three sections, is disjunctly distributed in eastern Asia and Central America (Mexico). Although the genus is well delimited, its subdivisions into sections and series have not been the subject of an explicit test of monophyly based on molecular data. A comprehensive examination of the evolutionary relationships within the genus is thus still lacking. We present a fossil-calibrated, molecular phylogeny of Deutzia based on two nuclear ribosomal DNA (ITS and 26S) and three chloroplast DNA regions (matK, rbcL, and trnL-F intergenic spacer). Within this framework, we examine character evolution in petal arrangement, filament shape, and the number of stamens, and infer the ancestral area and biogeographic history of the genus. Our molecular phylogeny suggests that Deutzia is monophyletic. Two major clades are recovered: one composed of the species of sect. Neodeutzia from Mexico, and the other containing all remaining Deutzia species of sections Mesodeutzia and Deutzia from SW China and Northeast Asia. The latter two Asian sections were each revealed to be polyphyletic. The induplicate petals, 2-dentate filaments, and polystemonous androecia are inferred to be ancestral character states. Biogeographic reconstructions suggest a Northeast Asian origin for the genus and subsequent spread to Mexico during the Oligocene and to SW China during the Miocene. Based on our results, a new infrageneric classification of Deutzia inferred from molecular phylogeny is required. We propose to merge sections Mesodeutzia and Deutzia to ensure the monophyly at the sectional level. Cooling trends during the Oligocene resulted in isolation, separating eastern Asian and Mexican taxa, while the warm period during the middle Miocene stimulated the diversification from Northeast Asia to SW China. The uplift in the Qinghai-Tibetan Plateau and monsoon regimes are important in promoting high species diversification of Deutzia in SW China.

[Ab] Abstract:PREMISE OF THE STUDY: Both historical and contemporary microevolutionary processes greatly influence the genetic patterns of East Asian plant endemics, but the spatial and temporal contexts of these processes remain poorly understood. Here, we investigate the relative influences of historical and contemporary gene flow and drift on the population genetic structure of Kirengeshoma palmata, a perennial herb from East China and South Japan. METHODS: We used data from nine polymorphic microsatellite loci to assess the levels of genetic diversity, effective population size, and contemporary and historical gene flow for six of the seven known populations. KEY RESULTS: We found high levels of inbreeding and allelic diversity within populations. Both contemporary and historical migration rates among populations were low, and a test of alternate models of population history strongly favored a model of long-term drift-migration equilibrium. We inferred declines in population size ca. 10,000-100,000 yr ago, but failed to detect recent declines. Bayesian clustering divided K. palmata populations into three genetic clusters, two of which were consistent with a glacial refugium hypothesis for two mountain ranges in East China. CONCLUSIONS: These results suggest that anthropogenic fragmentation has had little effect on the genetic characteristics of Chinese K. palmata. Rather, past decline in population size due to Late Pleistocene climate change as well as restricted pollen and seed dispersal may have contributed to low levels of both historical and contemporary gene flow, resulting in high genetic differentiation between adjacent mountain ranges due to genetic drift and inbreeding.

[Ab] Abstract:BACKGROUND: In East Asia, an increasing number of studies on temperate forest tree species find evidence for migration and gene exchange across the East China Sea (ECS) land bridge up until the last glacial maximum (LGM). However, it is less clear when and how lineages diverged in this region, whether in full isolation or in the face of post-divergence gene flow. Here, we investigate the effects of Quaternary changes in climate and sea level on the evolutionary and demographic history of Platycrater arguta, a rare temperate understorey shrub with disjunct distributions in East China (var. sinensis) and South Japan (var. arguta). Molecular data were obtained from 14 P. arguta populations to infer current patterns of molecular structure and diversity in relation to past (Last Interglacial and Last Glacial Maximum) and present distributions based on ecological niche modelling (ENM). A coalescent-based isolation-with-migration (IM) model was used to estimate lineage divergence times and population demographic parameters. RESULTS: Combining information from nuclear/chloroplast sequence data with nuclear microsatellites, our IM analyses identify the two varieties as genetically distinct units that evolved in strict allopatry since the mid-Pleistocene, c. 0.89 (0.51-1.2) Ma. Together with Bayesian Skyeline Plots, our data further suggest that both lineages experienced post-divergence demographic growth, followed by refugial isolation, divergence, and in the case of var. arguta post-glacial admixture. However, past species distribution modelling indicates that the species' overall distribution has not greatly changed over the last glacial cycles. CONCLUSIONS: Our findings highlight the important influence of ancient sea-level changes on the diversification of East Asia's temperate flora. Implicitly, they challenge the notion of general temperate forest expansion across the ECS land bridge, demonstrating instead its 'filter' effect owing to an unsuitable environment for certain species and their biological (e.g., recruitment) properties.

[Ab] Abstract:Nursery growing as well as common landscape hydrangeas are all susceptible to leaf spot fungus Cercospora hydrangeae. Warm and rainy weather causes the fungal spores to germinate quickly and spread over the plant leaves forming small purple or brown spots. Although Hydrangea plants are not killed by leaf spot, it detracts from the value of plants through the reduction of flowering and plant vigor. The aim of our study was to isolate, characterize and investigate the expression profile of Hydrangea macrophylla resistance (R) gene transcripts under C. hydrangeae fungus infection and examine their evolutionary relationships by phylogenetic analysis. R-genes are thought to be one of the components of the genetic resistance in plants and most of them encode nucleotide binding site-leucine rich repeat (NBS-LRR) proteins. A cDNA-NBS strategy was carried out using as template cDNAs isolated from control and infected plant leaves. The cDNA-NBS profiling gave an excellent bands reproducibility. Twenty new transcripts corresponding to NBS-LRR proteins were identified only in infected plants. The extent of positivity between the aminoacid sequences at NBS region varied from 45 to 90 %, which indicates the diversity among the RGAs. The results of this paper will provide a genomic framework for the further isolation of candidate disease resistance NBS-encoding genes in Hortensia, and contribute to the understanding of the evolutionary mode of NBS-encoding genes in Hydrangeaceae crops.

[Ab] Abstract:In evolutionary biology appropriate marker selection for the reconstruction of solid phylogenetic hypotheses is fundamental. One of the most challenging tasks addresses the appropriate choice of genomic regions in studies of closely related species. Robust phylogenetic frameworks are central to studies dealing with questions ranging from evolutionary and conservation biology, biogeography to plant breeding. Phylogenetic informativeness profiles provide a quantitative measure of the phylogenetic signal in markers and therefore a method for locus prioritization. The present work profiles phylogenetic informativeness of mostly non-coding chloroplast regions in an angiosperm lineage of closely related species: the popular ornamental tribe Hydrangeeae (Hydrangeaceae, Cornales, Asterids). A recent phylogenetic study denoted a case of resolution contrast between the two strongly supported clades within tribe Hydrangeeae. We evaluate the phylogenetic signal of 13 highly variable plastid markers for estimating relationships within and among the currently recognized monophyletic groups of this tribe. A selection of combined loci based on their phylogenetic informativeness retrieved more robust phylogenetic hypotheses than simply combining individual markers performing best with respect to resolution, nodal support and accuracy or those presenting the highest number of parsimony informative characters. We propose the rpl32-ndhF intergenic spacer (IGS), trnV-ndhC IGS, trnL-rpl32 IGS, psbT-petB region and ndhA intron as the best candidates for future phylogenetic studies in Hydrangeeae and potentially in other Asterids. We also contrasted the phylogenetic informativeness of coded indels against substitutions concluding that, despite their low phylogenetic informativeness, coded indels provide additional phylogenetic signal that is nearly free of noise. Phylogenetic relationships obtained from our total combined analyses showed improved resolution and nodal support with respect to recently published results.

[Ab] Abstract:The study was conducted on broiler birds to evaluate the anticoccidial efficacy of an extract of Chinese traditional herb Dichroa febrifuga Lour. One hundred broiler birds were assigned to five equal groups. All birds in groups 1-4 were orally infected with 1.5 × 10(4) Eimeira tenella sporulated oocysts and birds in groups 1, 2 and 3 were medicated with 20, 40 mg extract/kg feed and 2 mg diclazuril/kg feed, respectively. The bloody diarrhea, oocyst counts, intestinal lesion scores, and the body weight were recorded to evaluate the anticoccidial efficacy. The results showed that D. febrifuga extract was effective against Eimeria infection; especially 20 mg D. febrifuga extract/kg feed can significantly increase body weight gains and reduce bloody diarrhea, lesion score, and oocyst excretion in comparison to infected-unmedicated control group.
