A previous study indicated that Picea purpurea, a conifer in the Qinghai-Tibet Plateau (QTP), originated through HHS from P. likiangensis and P. wilsonii. To investigate this origin in more detail we analyzed transcriptome data for 114 individuals collected from 34 populations of the three Picea species from their core distributions in the QTP. Phylogenetic, principal component and admixture analyses of nuclear SNPs showed the species to be delimited genetically and that P. purpurea was admixed with approximately 60% of its ancestry derived from P. wilsonii and 40% from P. likiangensis. Coalescent simulations revealed the best-fitting model of origin involved formation of an intermediate hybrid lineage between P. likiangensis and P. -

Vietnam’s conifer flora has approximately 34 species that are indigenous to the country, making up about 5% of conifers known worldwide. Although conifers represent only less than 0.3% of the total number of higher vascular plant species of Vietnam, they are of great ecological, cultural and economic importance. Most conifer wood is prized for its high value in house construction, furniture making, etc. The decline of conifer populations in Vietnam has caused serious concern among scientists. Threats to conifer species are substantial and varied, ranging from logging (both commercial and subsistence), land clearing for agriculture, and forest fire. Over the past twelve years (1995-2006), Vietnam Botanical Conservation Program (VBCP), a scientific cooperation between the Missouri Botanical Garden in Saint Louis and the Institute of Ecology and Biological Resources in Hanoi, has conducted various studies on this important group of plants in order to gather baseline information necessary to make sound recommendations for their conservation and sustainable use. -
Diploid Hybrid Origin of Ostryopsis Intermedia (Betulaceae) in the Qinghai-Tibet Plateau Triggered by Quaternary Climate Change
Molecular Ecology (2014) 23, 3013–3027 doi: 10.1111/mec.12783 Diploid hybrid origin of Ostryopsis intermedia (Betulaceae) in the Qinghai-Tibet Plateau triggered by Quaternary climate change BINGBING LIU,*† RICHARD J. ABBOTT,‡ ZHIQIANG LU,† BIN TIAN† and JIANQUAN LIU* *MOE Key Laboratory of Bio-Resources and Eco-Environment, College of Life Science, Sichuan University, Chengdu 610065, China, †State Key Laboratory of Grassland Agro-Ecosystem, College of Life Science, Lanzhou University, Lanzhou 730000, China, ‡School of Biology, University of St Andrews, Mitchell Building, St Andrews, Fife, KY16 9TH, UK Abstract Despite the well-known effects that Quaternary climate oscillations had on shaping intraspecific diversity, their role in driving homoploid hybrid speciation is less clear. Here, we examine their importance in the putative homoploid hybrid origin and evolu- tion of Ostryopsis intermedia, a diploid species occurring in the Qinghai-Tibet Plateau (QTP), a biodiversity hotspot. We investigated interspecific relationships between this species and its only other congeners, O. davidiana and O. nobilis, based on four sets of nuclear and chloroplast population genetic data and tested alternative speciation hypotheses. All nuclear data distinguished the three species clearly and supported a close relationship between O. intermedia and the disjunctly distributed O. davidiana. Chloroplast DNA sequence variation identified two tentative lineages, which distin- guished O. intermedia from O. davidiana; however, both were present in O. nobilis. Admixture analyses of genetic polymorphisms at 20 SSR loci and sequence variation at 11 nuclear loci and approximate Bayesian computation (ABC) tests supported the hypothesis that O. intermedia originated by homoploid hybrid speciation from O. davidiana and O. -

Light and scanning electron microscopy observations indicated that this rust species was morphologically distinct from other known Diaphanopellis species and Chrysomyxa species in teliospore morphology and urediniospore surface structure. Diaphanopellis purpurea can be phylogenetically separated from other Chrysomyxa species based on analysis of internal transcribed spacer (ITS) partial gene sequences. The aecial stage of the new species was also confirmed. Keywords: Molecular phylogeny, phylogeny, Pucciniales, taxonomy Introduction Rust genus Diaphanopellis was established by Crane with the type species Diaphanopellis forrestii P. E. Crane occurring on Rhododendron selense Franch (Crane 2005, Kirk et al. 2008). Diaphanopellis is characterized by the teliospores enclosed in hyaline sheaths, and the uredinia surrounded by a peridium with ornamented cells (Barclay 1891, Balfour-Browne 1955, Crane 2005). Most rusts infecting Rhododendron belong to the genus Chrysomyxa, which are morphologically different from Diaphanopellis species in having uredinial peridium and distinct teliospores. Chrysomyxa species produce catenulate teliospores without gelatineous layers and uredinia covered by an inconspicuous peridium (Berndt 1999). -

We measured the genetic variation of 476 individuals from 88 populations using three maternally inherited plastid DNA markers (matK, rbcL and psbA- trnH), the biparentally inherited nuclear ribosomal internal transcribed spacer (nrITS) and amplified fragment length polymorphisms (AFLPs). We found that the plastid DNA, nrITS and AFLPs show considerable, recent differ- entiation among the species. We detected 14 plastid haplotypes (H1–H14), of which only three were shared among all species, and 30 nrITS ribotypes (S1–S30), of which one (S10) was shared between two species, O. -

The Convention on Biological Diversity Plant Conservation Report a Review of Progress in Implementing the Global Strategy for Plant Conservation (GSPC) Foreword
The Convention on Biological Diversity Plant Conservation Report A review of progress in implementing the Global Strategy for Plant Conservation (GSPC) Foreword t is a pleasure for me to contribute a foreword for this important report documenting the progress that has been made worldwide towards the achievement of the Global Strategy for Plant Conservation (GSPC). The adoption by the Convention on Biological Diversity of the Strategy in 2002 was a major achievement Ifor biodiversity conservation worldwide. It provided much needed and urgent recognition not only of the importance of plants for humanity but also of the critical threats faced by tens of thousands of plant species throughout the world. The unique importance of plants as essential renewable natural resources and as the basis for most terrestrial ecosystems demanded that such a strategy was required to help halt the loss of plant diversity and raise new awareness of the threats faced by plants. The Strategy was also an extremely innovative advance fo r the Convention too as it incorporated for the first time a series of targets for biodiversity conservation, aimed at achieving measurable plant conservation outcomes by 2010. The catalytic role of the Strategy in stimulating new programmes and initiatives at all levels has been significant too, linking a wide range of organisations and institutions in support of the Strategy. It is clear that much new plant conservation action has been encouraged and supported by the GSPC to date, including the generation of substantial new resources for biodiversity conservation that would not otherwise have become available without the Strategy. This report shows that substantial progress has been made towards reaching some of the GSPC targets, although for others it has been limited and will require renewed effort by the international community if they are to be achieved. -
Nootkatensis, Secondary Metabolites, Biological Activities, and Chemical Ecology
Journal of Chemical Ecology (2018) 44:510–524 https://doi.org/10.1007/s10886-018-0956-y REVIEW ARTICLE Yellow-Cedar, Callitropsis (Chamaecyparis) nootkatensis, Secondary Metabolites, Biological Activities, and Chemical Ecology Joseph J. Karchesy1 & Rick G. Kelsey2 & M. P. González-Hernández3 Received: 22 December 2017 /Revised: 26 March 2018 /Accepted: 28 March 2018 /Published online: 14 April 2018 # This is a U.S. government work and its text is not subject to copyright protection in the United States; however, its text may be subject to foreign copyright protection 2018 Abstract Yellow-cedar, Callitropsis nootkatensis, is prevalent in coastal forests of southeast Alaska, western Canada, and inland forests along the Cascades to northern California, USA. These trees have few microbial or animal pests, attributable in part to the distinct groups of biologically active secondary metabolites their tissues store for chemical defense. Here we summarize the new yellow-cedar compounds identified and their biological activities, plus new or expanded activities for tissues, extracts, essential oils and previously known compounds since the last review more than 40 years ago. Monoterpene hydrocarbons are the most abundant compounds in foliage, while heartwood contains substantial quantities of oxygenated monoterpenes and oxygenated sesquiterpenes, with one or more tropolones. Diterpenes occur in foliage and bark, whereas condensed tannins have been isolated from inner bark. Biological activities expressed by one or more compounds in these groups include fungicide, bactericide, sporicide, acaricide, insecticide, general cytotoxicity, antioxidant and human anticancer. The diversity of organisms impacted by whole tissues, essential oils, extracts, or individual compounds now encompasses ticks, fleas, termites, ants, mos- quitoes, bacteria, a water mold, fungi and browsing animals. -
