Two New Chrysomyxa Rust Species on the Endemic Plant, Picea Asperata in Western China, and Expanded Description of C
Phytotaxa 292 (3): 218–230 ISSN 1179-3155 (print edition) http://www.mapress.com/j/pt/ PHYTOTAXA Copyright © 2017 Magnolia Press Article ISSN 1179-3163 (online edition) https://doi.org/10.11646/phytotaxa.292.3.2 Two new Chrysomyxa rust species on the endemic plant, Picea asperata in western China, and expanded description of C. succinea JING CAO1, CHENG-MING TIAN1, YING-MEI LIANG2 & CHONG-JUAN YOU1* 1The Key Laboratory for Silviculture and Conservation of Ministry of Education, Beijing Forestry University, Beijing 100083, China 2Museum of Beijing Forestry University, Beijing 100083, China *Corresponding author: [email protected] Abstract Two new rust species, Chrysomyxa diebuensis and C. zhuoniensis, on Picea asperata are recognized by morphological characters and DNA sequence data. A detailed description, illustrations, and discussion concerning morphologically similar and phylogenetically closely related species are provided for each species. From light and scanning electron microscopy observations C. diebuensis is characterized by the nailhead to peltate aeciospores, with separated stilt-like base. C. zhuoni- ensis differs from other known Chrysomyxa species in the annulate aeciospores with distinct longitudinal smooth cap at ends of spores, as well as with a broken, fissured edge. Analysis based on internal transcribed spacer region (ITS) partial gene sequences reveals that the two species cluster as a highly supported group in the phylogenetic trees. Correlations between the morphological and phylogenetic features are discussed. Illustrations and a detailed description are also provided for the aecia of C. succinea in China for the first time. Keywords: aeciospores, molecular phylogeny, spruce needle rust, taxonomy Introduction Picea asperata Mast.is native to western China, widely distributed in Qinghai, Gansu, Shaanxi and western Sichuan. -

China 3School of Biology, Mitchell Building, University of St Andrews, St Andrews, Fife KY16 9TH, UK Article *equal contributions to this work; #corresponding author ([email protected]) Abstract An increasing number of species are thought to have originated by homoploid hybrid speciation (HHS), but in only a handful of cases are details of the process known. 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. -
Tree Planting Suggestions for Platte County, Nebraska
Shade Tree and Evergreen Planting Suggestions for Northeast Nebraska (Compiled by Kelly Feehan, Nebraska Extension, and Columbus Greenspace Advisory Group) There are no perfect trees. Ask about the characteristics/common problems of trees. Make sure a tree’s good points are a good fit for you and your landscape needs; and a tree’s bad points are acceptable to you and fit your landscape needs. Color listed is potential fall color. *Trees 30’ or less tall. Good to Great Shade Trees: *Washington Hawthorn (Crataegus phaenopyrum) Ginkgo (G. biloba) (male cultivars) (Yellow) Norway Maple (Acer platanoides “Emerald Bur oak (Quercus macrocarpa) Queen” or “Emerald luster”, ‘Deborah’, Chinkapin oak (Quercus muehlenbergii) ‘Parkway’) (yellow) (could get verticillium wilt) Red Oak (Quercus rubra) Scarlet Oak (Quercus coccinea) (Red) Shade Trees Worth Trying (untested in our English Oak (Quercus robur) area, but should do fine): White Oak (Quercus alba) (Brown to red) Lacebark Elm (Ulmus parvifolia) (yellow to State Street or Miyabei Maple (Acer miyabei reddish purple) ‘Morton’) (yellow) Black maple (Acer saccharum subsp. nigrum) Shingle Oak (Quercus impricaria) (yellow Silver Linden (Tilia tomentosa) brown to red brown) Shagbark Hickory (Carya ovata)(yellow, brown) Shumard Oak (Quercus shumardii) Kentucky coffeetree (Gymnocladus dioicus) Black Oak (Quercus veluntina) (Yellow) Bitternut Hickory (Carya cordiformis) Horse Chestnut (Aesculus hippocastanum) Turkish Filbert (Corylus colurna) *Ohio Buckeye (Aesculus glabra) (Reddish) Katsuratree (Cercidiphyllum -
EVERGREEN TREES for NEBRASKA Justin Evertson & Bob Henrickson
THE NEBRASKA STATEWIDE ARBORETUM PRESENTS EVERGREEN TREES FOR NEBRASKA Justin Evertson & Bob Henrickson. For more plant information, visit plantnebraska.org or retreenbraska.unl.edu Throughout much of the Great Plains, just a handful of species make up the majority of evergreens being planted. This makes them extremely vulnerable to challenges brought on by insects, extremes of weather, and diseases. Utilizing a variety of evergreen species results in a more diverse and resilient landscape that is more likely to survive whatever challenges come along. Geographic Adaptability: An E indicates plants suitable primarily to the Eastern half of the state while a W indicates plants that prefer the more arid environment of western Nebraska. All others are considered to be adaptable to most of Nebraska. Size Range: Expected average mature height x spread for Nebraska. Common & Proven Evergreen Trees 1. Arborvitae, Eastern ‐ Thuja occidentalis (E; narrow habit; vertically layered foliage; can be prone to ice storm damage; 20‐25’x 5‐15’; cultivars include ‘Techny’ and ‘Hetz Wintergreen’) 2. Arborvitae, Western ‐ Thuja plicata (E; similar to eastern Arborvitae but not as hardy; 25‐40’x 10‐20; ‘Green Giant’ is a common, fast growing hybrid growing to 60’ tall) 3. Douglasfir (Rocky Mountain) ‐ Pseudotsuga menziesii var. glauca (soft blue‐green needles; cones have distinctive turkey‐foot bract; graceful habit; avoid open sites; 50’x 30’) 4. Fir, Balsam ‐ Abies balsamea (E; narrow habit; balsam fragrance; avoid open, windswept sites; 45’x 20’) 5. Fir, Canaan ‐ Abies balsamea var. phanerolepis (E; similar to balsam fir; common Christmas tree; becoming popular as a landscape tree; very graceful; 45’x 20’) 6. -

This genus includes two varieties: Thujopsis dolabrata (L.f.) Siebold et Zucc. var. dolabrata (southern variety, Td) and Thujopsis dolabrata (L.f.) Siebold et Zucc. var. hondae Makino (northern variety, Th). The aim of this study is to understand the phylogeographic and genetic population relationships of the genus Thujopsis for the conservation of genetic resources and future breeding. A total of 609 trees from 22 populations were sampled, including six populations from the Td distribution range and 16 populations from the Th distribution range. The genotyping results for 19 expressed sequence tag (EST)-based simple sequence repeat (SSR) markers, followed by a structure analysis, neighbor-joining tree creation, an analysis of molecular variance (AMOVA), and hierarchical F statistics, supported the existence of two genetic clusters related to the distribution regions of the Td and Th varieties.
