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. -

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.

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. -

A checklist of 82 ant species recorded from Gambia is given. Key words: ants, faunistics, Gambia, new country records. INTRODUCTION Ants fauna of Gambia (West Africa) is poorly known. Literature data, AntWeb and other Internet resources recorded only 59 species from this country. For comparison from Senegal, which surrounds three sides of Gambia, 89 species have been recorded so far. Both of these records seem poor when compared with 654 species known from the whole western Africa (SHUCKARD 1840, ANDRÉ 1889, EMERY 1892, MENOZZI 1926, SANTSCHI 1939, LUSH 2007, ANTWIKI 2017, ANTWEB 2017, DIAMÉ et al. 2017, TAYLOR 2018). Most records from Gambia come from general web checklists of species. Unfortunately, they lack locality data, date of sampling, collector name, coordinates of the locality and notes on habitats. -
List of Indian Ants (Hymenoptera: Formicidae) Himender Bharti
List of Indian Ants (Hymenoptera: Formicidae) Himender Bharti Department of Zoology, Punjabi University, Patiala, India - 147002. (email: [email protected]/[email protected]) (www.antdiversityindia.com) Abstract Ants of India are enlisted herewith. This has been carried due to major changes in terms of synonymies, addition of new taxa, recent shufflings etc. Currently, Indian ants are represented by 652 valid species/subspecies falling under 87 genera grouped into 12 subfamilies. Keywords: Ants, India, Hymenoptera, Formicidae. Introduction The following 652 valid species/subspecies of myrmecology. This species list is based upon the ants are known to occur in India. Since Bingham’s effort of many ant collectors as well as Fauna of 1903, ant taxonomy has undergone major myrmecologists who have published on the taxonomy changes in terms of synonymies, discovery of new of Indian ants and from inputs provided by taxa, shuffling of taxa etc. This has lead to chaotic myrmecologists from other parts of world. However, state of affairs in Indian scenario, many lists appeared the other running/dynamic list continues to appear on web without looking into voluminous literature on http://www.antweb.org/india.jsp, which is which has surfaced in last many years and currently periodically updated and contains information about the pace at which new publications are appearing in new/unconfirmed taxa, still to be published or verified.

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. -
