Systematic Studies of Parasenecio (Asteraceae-Senecioneae) I J. Jpn. Bot. 90: 92–97 (2015) Systematic Studies of Parasenecio (Asteraceae-Senecioneae) I. Parasenecio katoanus, a New Species from Yamagata Prefecture, Northern Honshu, Japan Yuichi KADOTA Department of Botany, National Museum of Nature and Science, 4–1–1, Amakubo, Tsukuba, 305-0005 JAPAN E-mail: [email protected] (Accepted on November 1, 2014) A new species of Parasenecio (Asteraceae-Senecioneae), P. katoanus Kadota, is described from the Shônai region, Yamagata Pref., northern Honshu, Japan. Parasenecio katoanus is distinguished from P. nikomontanus (Matsum.) H. Koyama by having 1) triangular-pentagonal, somewhat fleshy, dimly lustrous, usually glabrous leaf blades, 2) longer involucres with acute involucral phyllaries, 3) longer achenes, and 4) ascending peduncles at an acute angle. It was found that the flowers were fragrant in the midst of flowering time. Parasenecio katoanus is hitherto known only from the Shônai area of Yamagata Pref. Key words: Asteraceae, Japan, new species, Parasenecio katoanus, the Shônai region, Yamagata Prefecture. This is the first part of a series of systematic blades and is commonly distributed on the studies of the genus Parasenecio (Asteraceae- Japan Sea side of Honshu Island ranging from Senecioneae). The genus consists of more Akita Pref. to Shimane Pref. (Koyama 1995, than 60 species (Chen 1999). It shows an East Kadota unpubl.). The Japanese vernacular name Asian and Eastern North American disjunct ‘Ô-kani-kômori’ is derived from the shape of distribution pattern and its considerable number leaf blades, of which ‘Kani’ means the shape of of species are recognized in the Sino-Japanese crab carapace. floristic region (Koyama 1983, Chen 1999, Parasenecio nikomontanus also occurs Kadota 2009). In Japan the genus extends widely fairly commonly throughout Yamagata throughout the Islands from Hokkaido to Kyushu Prefecture, northern Japan. However, Mr. Shin- (except for the Ryukyus) and several species of ei Kato, Tsuruoka, Yamagata Prefecture, found the genus are geographically differentiated into some populations of peculiar Parasenecio many local taxa (Kadota 2009). plants at Soegawa in the suburb of Tsuruoka Parasenecio nikomontanus (Matsum.)

    Metabolitos secundarios con actividad antifúngica en la tribu Senecioneae (Asteraceae) García Contreras, María Paula1 [email protected] 1.Pontificia Universidad Javeriana. Facultad de Ciencias. Unidad de Investigaciones Agropecurias (UNIDIA). Grupo de investigación en fitoquímica (GIFUJ) RESUMEN Los hongos patógenos de plantas representan grandes pérdidas para el sector floricultor y su tratamiento se ha visto limitado debido a la toxicidad de los fungicidas y al desarrollo de mecanismos de resistencia por parte de los patógenos. Los metabolitos secundarios de las plantas se han estudiado como una potencial alternativa para su tratamiento debido a su efectividad como sustancias antimicrobianas, particularmente dentro de la familia Asteraceae, la tribu Senecioneae se ha mostrado como un grupo potencial para la búsqueda de metabolitos secundarios con actividad biológica. Por lo tanto, el propósito de esta revisión es recopilar los estudios disponibles de actividad antifúngica para la tribu Senecioneae con el fin de identificar potenciales compuestos para la investigación en fungicidas naturales aplicables a fitopatógenos de cultivos de flores. Palabras clave: Asteraceae, Senecioneae, metabolitos secundarios, fitoquímica, aceites esenciales, monoterpenos, sesquiterpenos, alcaloides pirrolizidínicos, actividad antifúngica, fitopatógenos. INTRODUCCIÓN Las plantas son susceptibles a una gran variedad de agentes bióticos que pueden afectar su crecimiento, desarrollo y reproducción. Dentro de estos, los hongos patógenos tienen la capacidad de infectar tejidos como la raíz y el tallo, dificultando el transporte de agua y nutrientes, o las hojas, impidiendo procesos de intercambio gaseoso y fotosíntesis (Struck 2006). Debido a que estos patógenos pueden atacar plantas de interés económico como los cultivos de flores y generar grandes pérdidas (Cámara de Comercio de Bogotá 2015), los productores acuden a estrategias rápidas y sencillas para su tratamiento como la aplicación y rotación de fungicidas sobre los cultivos (Lesmes-Fabian & Binder 2013).

    Pest Risk Analysis for Coleosporium asterum STAGE 1: INITIATION 1. What is the name of the pest? Coleosporium asterum (Dietel) Sydow & P. Sydow. Taxonomic position: Kingdom: Fungi Division: Basidiomycota Class: Pucciniomycetes Order: Pucciniales Family: Coleosporiaceae Common name(s): Western pine-aster rust, needle cast of red pine, rust of Solidago, rust of aster. Synonyms C. asterum has the following synonyms (Anon., 2014): Stichopsora asterum Uredo solidaginis Coleosporium solidaginis Coleosporium solidaginis f. solidaginis Peridermium montanum Coleosporium solidaginis f. carpesii Special notes on nomenclature and taxonomy: The genus Coleosporium is currently comprised of >2001 species. In the first UK Pest Risk Analysis (PRA) for C. asterum (Jones, 2005) species numbers were described as ‘numerous’ and ‘doubtfully distinct morphologically’. The name of the pathogen and the hosts which it is reported to infect has been the subject of much debate and revision over many years (see e.g. Raabe and Pyeatt, 1990). Helfer (2013) commented that ‘most authors agree that the European taxa of Coleosporium are indistinguishable in their morphology’. He also stated that the taxa of Coleosporium are ‘seriously confused’; with host specificity appearing to restrict the host-range in some taxa, but not in others; and the use of molecular methods to define taxa being ‘in its infancy’. Because of this, there is doubt over the accuracy of some of the country and host records of C. asterum presented in this PRA as well as 1234 species records in Index Fungorum (Anon., 2014) - accessed 18 February 2014 Page 1 of 46 Author: Dr Claire Sansford, Independent Plant Health Consultant, UK; April 23rd 2015 the current distribution of the pest.

Some floral micromorphological characters of this species, including shape of anther bases, configuration of anther collars, and anther endothecial tissue cell wall thickenings, are confirmed to perfectly match those of Senecio and this has obviously resulted in the placement of the species within that genus. Chromosome counts indicate S. kumaonensis has 2n = 40, a number common to Senecio and Synotis but not occurring in Parasenecio (the cor- rect generic name for the Asian species previously referred to Cacalia), which has 2n = 52, 58, and 60. The presence of six subterminal-centromeric (st) chromosomes in the karyotype of S. kumaonensis, however, lends strong support to the close relationship of this species to Synotis.

    Alien species in Norway – with the Norwegian Black List 2012 Alien species in Norway – with the Norwegian Black List 2012 presents an overview of ecological impact assessments of alien species which reproduce in Norwegian territories. The assessments are based upon a new and semi- quantitative set of criteria, where the species’ invasion potential and ecological effect are considered. The work has been carried out by 11 groups of experts who have treated ca. 2500 species. Impact assessments have been made for 1180 alien species which reproduce in Norwegian territories and for 134 species which might arrive in Norway with the aid of humans in the future – so called ‘door knockers’. A total of 106 species are categorised as having a severe impact, 111 species as having a high impact, 198 species as having a potentially high impact, 399 species as having a low impact, and 366 species as having no known impact in Norwegian nature. In addition, species inform- ation has been gathered for 1071 alien species which do not reproduce on the Norwegian mainland and territorial waters, and 69 non-reproducing alien species observed in Svalbard.

    Persoonia 24, 2010: 81–92 www.persoonia.org RESEARCH ARTICLE doi:10.3767/003158510X501696 Molecular phylogeny and taxonomy of Eurasian Neoerysiphe species infecting Asteraceae and Geranium V. Heluta1, S. Takamatsu 2, M. Harada 2, S. Voytyuk1 Key words Abstract Because Eurasian samples of Neoerysiphe collected on the Asteraceae were not identical in morphology, the molecular and morphological differences among these specimens were compared with those of the American 28S rDNA N. cumminsiana. Neoerysiphe on Asteraceae was found to consist of at least four different species. Three of them Asteraceae are described as new species, viz. N. hiratae, N. joerstadii, and N. nevoi. Neoerysiphe hiratae is a Japanese species Erysiphales parasitizing hosts belonging to the genera Cacalia and Ligularia (tribe Senecioneae). Neoerysiphe joerstadii was Japan found in Israel on Phagnalon rupestre (tribe Gnaphalieae). Neoerysiphe nevoi was recorded in Israel and Ukraine Mediterranean region on a number of hosts in different genera but all belonging to tribe Cichorieae. Thus, Eurasian Neoerysiphe species new species infecting the Asteraceae are strongly specialised to particular tribes of this family. Phylogenetic analyses indicated rDNA ITS region that the three new species were not closely allied. Neoerysiphe hiratae is related to the American N. cumminsiana systematics and species belonging to Oidium subg. Striatoidium. Neoerysiphe nevoi is sister to N. geranii, and N. joerstadii is allied to N. galii. In addition, Ukrainian Neoerysiphe samples on Geranium were phylogenetically and morphologically identical to Japanese samples of N. geranii, and this fungus seems to be an invasive species in Ukraine.

These species are morphologically distinct; however, their relation- ships appear complex. A phylogenetic analysis of members of the complex and selected taxa of the tribe Senecioneae was conducted using chloroplast (ndhF and trnL-F) and nuclear (ITS) sequences. Phylogenetic trees were constructed from individual and combined datasets of the three diVerent sequences. All analyses suggested that Doronicum, a genus that has been included in the Tussilagininae, should be excluded from this subtribe and placed at the base of the tribe Senecioneae. In addition, the Tussilagininae should be broadly circumscribed to include the Tephroseridinae.
