  • Molecular Phylogenetic Analyses Reveal a Close Evolutionary Relationship Between Podosphaera (Erysiphales: Erysiphaceae) and Its Rosaceous Hosts
    Persoonia 24, 2010: 38–48 www.persoonia.org RESEARCH ARTICLE doi:10.3767/003158510X494596 Molecular phylogenetic analyses reveal a close evolutionary relationship between Podosphaera (Erysiphales: Erysiphaceae) and its rosaceous hosts S. Takamatsu1, S. Niinomi1, M. Harada1, M. Havrylenko 2 Key words Abstract Podosphaera is a genus of the powdery mildew fungi belonging to the tribe Cystotheceae of the Erysipha­ ceae. Among the host plants of Podosphaera, 86 % of hosts of the section Podosphaera and 57 % hosts of the 28S rDNA subsection Sphaerotheca belong to the Rosaceae. In order to reconstruct the phylogeny of Podosphaera and to evolution determine evolutionary relationships between Podosphaera and its host plants, we used 152 ITS sequences and ITS 69 28S rDNA sequences of Podosphaera for phylogenetic analyses. As a result, Podosphaera was divided into two molecular clock large clades: clade 1, consisting of the section Podosphaera on Prunus (P. tridactyla s.l.) and subsection Magnicel­ phylogeny lulatae; and clade 2, composed of the remaining member of section Podosphaera and subsection Sphaerotheca. powdery mildew fungi Because section Podosphaera takes a basal position in both clades, section Podosphaera may be ancestral in Rosaceae the genus Podosphaera, and the subsections Sphaerotheca and Magnicellulatae may have evolved from section Podosphaera independently. Podosphaera isolates from the respective subfamilies of Rosaceae each formed different groups in the trees, suggesting a close evolutionary relationship between Podosphaera spp. and their rosaceous hosts. However, tree topology comparison and molecular clock calibration did not support the possibility of co-speciation between Podosphaera and Rosaceae. Molecular phylogeny did not support species delimitation of P. aphanis, P.

  • Bush Cherries (Prunus Spp.) Exposure: Full Sun to Part Shade, Zone 2 - 7
    Bush Cherries (Prunus spp.) Exposure: Full sun to part shade, zone 2 - 7. Useful Plants Soil: All cherries require well-drained soil. Bush cherries are tolerant of NURSERY different soil types. Growth habits: • Nanking cherry (Prunus tomentosa): A multiple-stemmed bush cherry from 6 to 10 feet tall and 4 to 5 feet wide. Beautiful, slightly fuzzy foliage and beautiful dark reddish bark for winter interest. Whitish-pink cherry flowers in March followed by delicious small bright red cherries in late May to early June. • Korean bush cherry (Prunus japonica): A fine-textured bush cherry with fuzzy leaves that grows to 5 to 8 feet in height and width. • Fall-ripening bush cherry (Prunus japonica x jacquemontii): A small, shrubby, fine-textured bush cherry that grows to 5 feet in height and width. Landscape uses: Hedge, specimen, orchard, or foundation planting. All are attractive to bees and other pollinators, and make good wildlife habitat. Edible/Medicinal properties: • Nanking cherry: The small sweet/tart, juicy red cherries are the first bush fruit of the season to ripen and are quite tasty for fresh eating or processing. We love this fruit and are always excited when they begin to ripen up. You’ll have to race your wildlife for these tasty beauties. • Korean bush cherry: These bush cherries produce average-sized, bright red cherries in mid summer. The cherries are similar to Nanking cherries, but sweeter. Less productive than Nanking cherry. The cherries are great for fresh eating and can be frozen for delicious winter snacks. They also make tasty juice and are high in anthocyanins and other antioxidants.

  • Flood Tolerant Prunus
    "SNA RESEARCH CONFERENCE - VOL. 38-1993" tile drains separated from the soil by a semipermeable fabric. Pipe or holes shall be prevented from clogging up by wrapping or covering with a filter fabric. References: 1. City of Raleigh Parks and Recreation Dept. 1991 ,” Policies and Standards Governing Activities Which Impact City Trees” Flood Tolerant Prunus Thomas G. Ranney North Carolina Nature of Work: Many species of Prunus are notoriously intolerant of poor drainage. In some cases, inundation of the root system for only a few days can be sufficient to kill certain of these plants (1). Research conducted on commercial fruit trees, however, has shown there to be considerable variation in flood tolerance among different species and hybrids of prunus (3). For example, comparisons among cherry rootstocks have shown that P. avium is better adapted to poorly drained conditions than is P. mahaleb (2). Conventionally, many of the flowering prunus are propagated by budding and grafting. Recently, however, there has been greater interest in growing flowering Prunus from rooted cuttings. Although this type of propagation can simplify production practices and minimize problems of rootstock suckering, there is little information on the adaptability ornamental Prunus trees when grown on their own roots. The objective of this project was to evaluate differential sensitivity of ownrooted taxa of Prunus to acute flooding. Taxa studied included: P. avium ‘F 12/1’, Prunus caroliniana, P. incisa x campanulata ‘Okame’, P. japonica, P. mume ‘Peggy Clark’, P. x ‘Newport’, P. sargentii, P. serru/ata ‘Kwanzan’, P. subhirtella ‘Autumnalis’, P. virginiana ‘Canada Red’, and P. x yedoensis.

    EPPO Datasheet: Popillia japonica Last updated: 2020-11-25 IDENTITY Preferred name: Popillia japonica Authority: Newman Taxonomic position: Animalia: Arthropoda: Hexapoda: Insecta: Coleoptera: Scarabaeidae Common names: Japanese beetle view more common names online... EPPO Categorization: A2 list view more categorizations online... EU Categorization: A2 Quarantine pest (Annex II B) EPPO Code: POPIJA more photos... Notes on taxonomy and nomenclature Popillia japonica is a member of the order Coleoptera, family Scarabaeidae, subfamily Rutelinae and tribe Anomlini. HOSTS Popillia japonica is a highly polyphagous species and the adults can be found feeding on a wide range of trees, shrubs, wild plants and crops (EPPO, 2016). The odour and the location in direct sun play a pivotal role in the selection of host plants by the beetle. The host range of P. japonica includes more than 300 different ornamental and agricultural plant hosts. Adults have been recorded feeding on the foliage, flowers, and fruits, larvae on grass roots (USDA, 2020). In its native area (Japan), the host range appears to be smaller than in North America. In the EPPO region, the adults of P. japonica feed on vines, fruit trees, forest plants, crops, vegetables, ornamental plants and wild species. In 2006, EPPO stated that Vitis spp. and Zea mays are the main hosts of concern in Europe (EFSA, 2019). In Italy, adults were recently found ready to emerge from the soil of rice paddies, but no damage has been recorded. Host list: Acer palmatum, Acer platanoides, Actinidia, Aesculus

  • Tranzschelia Discolor (Fuckel) Tranzschel & Litv., 1939
    -- CALIFORNIA D EPAUMENT OF cdfa FOOD & AGRICULTURE ~ California Pest Rating Proposal for Tranzschelia discolor (Fuckel) Tranzschel & Litv., 1939 Synonym Tranzschelia pruni-spinosae var. discolor (Fuckel) Dunegan, 1938 Stone fruit rust Domain: Eukaryota; Kingdom: Fungi; Phylum: Basidiomycota; Subphylum: Pucciniomycotina; Class: Pucciniomycetes; Order: Pucciniales Family: Uropyxidaceae Current Pest Rating: C Proposed Pest Rating: C Comment Period: 12/07/2020 through 01/21/2021 Initiating Event: A request for clarification on the rating for Tranzschelia discolor came from a County plant pathologist. The risk to California from T. discolor is described herein and a permanent rating is proposed. History & Status: Background: Tranzschelia discolor is a rust pathogen, mainly attacking plants in the genus Prunus. Almond, peach, and prune are the most susceptible hosts in California, but it also affects apricot, cherry, nectarine, and plum. It is a macrocyclic, heteroecious rust with multiple spore stages that develop on two different hosts. However, the alternate host is not necessary for epidemics to develop on Prunus. Prunus is the primary host and produces stage II (urediniospores), stage III (teliospores), and stage IV (basidiospores). The alternate host is Anemone coronaria which produces stage 0 (spermatia) and stage 1 (aeciospores). Urediniospores are the repeating, vegetative spores and can autoinfect their Prunus host. The pathogen can be separated into formae speciales (f. sp.), based on host specificity in the uredinial infection stage. Bolkan et al., 1985, showed that the uredinial stages are specific to the -- CALIFORNIA D EPAUMENT OF cdfa FOOD & AGRICULTURE ~ host where they are produced and do not cross-infect. These forms are T. discolor f. sp.

  • Genetic Relationships Among 10 Prunus Rootstock Species from China, Based on Simple Sequence Repeat Markers
    J. AMER.SOC.HORT.SCI. 141(5):520–526. 2016. doi: 10.21273/JASHS03827-16 Genetic Relationships among 10 Prunus Rootstock Species from China, Based on Simple Sequence Repeat Markers Qijing Zhang and Dajun Gu1 Liaoning Institute of Pomology, Yingkou, Liaoning 115009, People’s Republic of China ADDITIONAL INDEX WORDS. microsatellite markers, banding patterns, phylogenetic analysis, subgenus classification, rootstock breeding ABSTRACT. To improve the efficiency of breeding programs for Prunus rootstock hybrids in China, we analyzed the subgenus status and relationship of 10 Chinese rootstock species, by using 24 sets of simple sequence repeat (SSR) primers. The SSR banding patterns and phylogenetic analysis indicated that subgenus Cerasus is more closely related to subgenus Prunophora than to subgenus Amygdalus, and that subgenus Lithocerasus is more closely related to subgenus Prunophora and subgenus Amygdalus than to subgenus Cerasus. In addition, Prunus triloba was more closely related to Prunus tomentosa than to the members of subgenus Amygdalus. Therefore, we suggest that P. tomentosa and P. triloba should be assigned to the same group, either to subgenus Lithocerasus or Prunophora, and we also propose potential parent combinations for future Prunus rootstock breeding. Prunus (Rosaceae) is a large genus with significant eco- peach, whereas Prunus salicina and Prunus sibirica can be nomic importance, since it includes a variety of popular stone used as a rootstock for cherry, plum, apricot, and peach. fruit species [e.g., peach (Prunus persica), apricot (Prunus Hybridization among Prunus species has been successful and armeniaca), almond (Prunus dulcis), and sweet cherry (Prunus has been taken up as an effective strategy for improving avium)].

  • Chollipo and Korea, 1997
    Chollipo and Korea, 1997 Dr. John David Tobe (with excerpts and edits from John Gallagher snd Robert Butts) On the morning of April 19 the coastline of South Korea came into view shortly after flying over Japan and the Sea of Japan. As we began our descent toward the South Korean peninsula, the mountains enshrouded in mist slowly revealed the details of silver rivers and dark rows of peaks. The spring sunlight outlined the natural geography of Korea, unfolding the landscape into ever finer detail as we descended —roads, vehicles, houses, and individual trees came into view. Pink clouds, cherry trees in flower, drifted along mountain slopes punctuated by Buddhist temples and valley villages. The 34th annual spring meeting of the Magnolia Society (TMS) was held in South Korea, graciously hosted by Mr. C. Ferris Miller of the Chollipo Arboretum, Chung Nam, South Korea. Also known by his adopted South Korean name, Min Pyong-Gal, Ferris has been an instrumental member of the Magnolia Society and has assembled, with great aesthetic sensibilities, one of the world's best collections of cultivated magnolias at the Chollipo Arboretum. The Magnolia Society will be forever grateful to the hospitality shown to the members during one of our most exotic and our only trip as a society to Asia. Ferris was careful to orchestrate our trip so as to introduce the Magnolia Society to the many botanical wonders of South Korea. He did so with great success. In addition, the tours of palaces, ancient cities and temples gave us a sense of the richness of the South Korean culture and history.

T. Andersen and T. S. Weir Fruit breeding has been a recognized responsibility of the University Minnesota since 1878. Early successes encouraged the 1907 state legislature to establish a University Fruit Breeding Farm near Excelsior, about 20 miles south­ west of Minneapolis. From the outset, work in stone fruit breeding has been prominent; hardy plums with fruit qualities superior to those of native species have been sought. This search led to interspecies hybridization of many Prunus varieties and the selection and propagation of improved plants.
