Phytopythium: Molecular Phylogeny and Systematics
Persoonia 34, 2015: 25–39 www.ingentaconnect.com/content/nhn/pimj RESEARCH ARTICLE http://dx.doi.org/10.3767/003158515X685382 Phytopythium: molecular phylogeny and systematics A.W.A.M. de Cock1, A.M. Lodhi2, T.L. Rintoul 3, K. Bala 3, G.P. Robideau3, Z. Gloria Abad4, M.D. Coffey 5, S. Shahzad 6, C.A. Lévesque 3 Key words Abstract The genus Phytopythium (Peronosporales) has been described, but a complete circumscription has not yet been presented. In the present paper we provide molecular-based evidence that members of Pythium COI clade K as described by Lévesque & de Cock (2004) belong to Phytopythium. Maximum likelihood and Bayesian LSU phylogenetic analysis of the nuclear ribosomal DNA (LSU and SSU) and mitochondrial DNA cytochrome oxidase Oomycetes subunit 1 (COI) as well as statistical analyses of pairwise distances strongly support the status of Phytopythium as Oomycota a separate phylogenetic entity. Phytopythium is morphologically intermediate between the genera Phytophthora Peronosporales and Pythium. It is unique in having papillate, internally proliferating sporangia and cylindrical or lobate antheridia. Phytopythium The formal transfer of clade K species to Phytopythium and a comparison with morphologically similar species of Pythiales the genera Pythium and Phytophthora is presented. A new species is described, Phytopythium mirpurense. SSU Article info Received: 28 January 2014; Accepted: 27 September 2014; Published: 30 October 2014. INTRODUCTION establish which species belong to clade K and to make new taxonomic combinations for these species. To achieve this The genus Pythium as defined by Pringsheim in 1858 was goal, phylogenies based on nuclear LSU rRNA (28S), SSU divided by Lévesque & de Cock (2004) into 11 clades based rRNA (18S) and mitochondrial DNA cytochrome oxidase1 (COI) on molecular systematic analyses. -
Eucalyptus 2018 17-21 September 2018, Le Corum, Montpellier - France
Eucalyptus 2018 17-21 September 2018, Le Corum, Montpellier - France Eucalyptus 2018 Managing Eucalyptus plantations under global changes Abstracts Book Foreword Eucalyptus trees cover about 20 million hectares in more than 90 countries around the world with major centers in Brazil (5.7 m ha), India (3.9 m ha) and China (4.5 m ha). Eucalypts are widely grown in commercial plantations to produce raw material for the industry (pulp and paper, charcoal, sawn timber, wood panels) but also in small woodlots for the production of firewood and charcoal for domestic uses. The considerable expansion of these plantations in recent decades reflects major competitive advantages of eucalypts relative to other tree species in terms of productivity, tolerance to biotic and abiotic stresses, wood quality for a wide variety of uses and ability to be managed in coppice. However, the requirements in water and nutrients of eucalypt trees are high to reach high biomass productions and the environmental impact of the silviculture is still a matter of debate. In a context of global changes with more frequent drought events, temperature rise and rapid expansion of pests and diseases, the sustainability of eucalypt plantations is of concern in many regions. Interdisciplinary research is urgently needed to improve the adaptation of eucalypt plantations to global changes. Cirad and I-Site MUSE organize an international conference under the auspices of IUFRO (Division 2.08.03 Improvement and culture of eucalypts and Division 1.02.01 Ecology and silviculture of plantation forests in the tropics) to present recent advances likely to improve the management of eucalypt plantations in tropical, sub-tropical and Mediterranean regions. -

Investigations into the declining health of alder (Alnus glutinosa) along the river Lagan in Belfast, including the first report of Phytophthora lacustris causing disease of Alnus in Northern Ireland Richard O Hanlon (1, 2)* Julia Wilson (2), Deborah Cox (1) (1) Agri-Food and Biosciences Institute, Belfast, BT9 5PX, Northern Ireland, UK. (2) Queen’s University Belfast, Northern Ireland, UK * [email protected] Additional key words: Plant health, Forest pathology, riparian, root and collar rot. Abstract Common alder (Alnus glutinosa) is an important tree species, especially in riparian and wet habitats. Alder is very common across Ireland and Northern Ireland, and provides a wide range of ecosystem services. Surveys along the river Lagan in Belfast, Northern Ireland led to the detection of several diseased Alnus trees. As it is known that Alnus suffers from a Phytophthora induced decline, this research set out to identify the presence and scale of the risk to Alnus health from Phytophthora and other closely related oomycetes. Sampling and a combination of morphological and molecular testing of symptomatic plant material and river baits identified the presence of several Phytophthora species, including Phytophthora lacustris. A survey of the tree vegetation along an 8.5 km stretch of the river revealed that of the 166 Alnus trees counted, 28 were severely defoliated/diseased and 9 were dead. -

Phytophthora Pathogens Threaten Rare Habitats and Conservation Plantings
Phytophthora pathogens threaten rare habitats and conservation plantings Susan J. Frankel1, Janice Alexander2, Diana Benner3, Janell Hillman4 & Alisa Shor5 Abstract Phytophthora pathogens are damaging native wildland vegetation including plants in restoration areas and botanic gardens. The infestations threaten some plants already designated as endangered and degrade high-value habitats. Pathogens are being introduced primarily via container plant nursery stock and, once established, they can spread to adjacent areas where plant species not previously exposed to pathogens may become infected. We review epidemics in California – caused by the sudden oak death pathogen Phytophthora ramorum Werres, De Cock & Man in ‘t Veld and the frst USA detections of P. tentaculata Krber & Marwitz, which occurred in native plant nurseries and restoration areas – as examples to illustrate these threats to conservation plantings.

It is native to U.S. but during the 20th century it has dispersed through Europe, Asia and western China. It continues to expand in an east and southeast direction. Damages are caused by larvae and adults. Their feeding on potato plant leaves can cause complete defoliation and lead to a large yield loss. After the long period of using only chemical control measures, the emergence of resistance increased and some new and different methods come to the fore. The main focus of this review is on new approaches to the old CPB control problem. We describe the use of Bacillus thuringiensis and RNA interference (RNAi) as possible solutions for the future in CPB management. RNAi has proven successful in controlling many pests and shows great potential for CPB control. Better understanding of the mechanisms that affect efficiency will enable the development of this technology and boost potential of RNAi to become part of integrated plant protection in the future. -
