Salvas The Connecticut Agricultural Experiment Station – Record of the Year 2017-2018 8 RETIREMENTS Ms. Kathryn Soleski Ms. Kathryn Soleski began her State career in 1989 and joined the Business Office staff of The Connecticut Agricultural Experiment Station in 1990 as clerk- typist. She always made suggestions to improve processes and service and moved up through the ranks to her current position of Purchasing Assistant. As a hard- working, loyal and dedicated Station staff member, Kathy provided outstanding purchasing and administrative support to the agency’s research staff in a courteous and professional manner. She was quick to learn and adapt to agency modernization and the agency’s transformation to the completely automated State- wide accounting system CORE-CT. Ms. Soleski was polite and courteous with co-workers and state residents who called upon the Station for assistance or information. Her dedication to her responsibilities and loyalty to the Experiment Station along with her cheerful personality are qualities that will leave a void and certainly be missed. A true public servant and ambassador for the Experiment Station and the State of Connecticut, for twenty-eight years, we honor Ms. Kathryn Soleski and her many important contributions on the occasion of her retirement. Michael C. Thomas Michael Thomas joined the staff of The Connecticut Agricultural Experiment Station in April 1999 as a Research Assistant II in the Department of Entomology where he assisted Dr. Chris Maier in studies on forest and apple orchard insect pests. A year later he was promoted to Research Technician I, and transferred to the Department of Soil & Water, (now the Department of Environmental Sciences and Center for Vector Biology & Zoonotic Diseases) where he assisted Dr. Theodore Andreadis and later Dr. Philip Armstrong in the statewide Mosquito/Arbovirus Surveillance Program and assisted in studies on the ecology of mosquitoes and epidemiology of mosquito-borne diseases. In 2004, he was promoted to Research Technician II. An outstanding ornithologist and field naturalist with taxonomic expertise in local insect fauna, most notably dragonflies and robber flies, Michael quickly mastered the identification of mosquitoes, and over the years became an expert on mosquito ecology and natural history throughout the region. This culminated in publication of the Identification Guide to the Mosquitoes of Connecticut, which he co-authored with Dr. Andreadis and Mr. John Shepard. For eighteen years, Michael made immeasurable contributions to the Station’s mosquito research and surveillance programs, identifying and processing mosquitoes for virus isolation, maintaining mosquito and animal colonies, conducting bioassays with potential biological control agents and establishing the Station’s reference collection of local mosquito species. In the field, Michael routinely traversed the State uncovering breeding sites for native and invasive species, setting specialized traps and collecting mosquitoes in variety habitats across the entire spectrum, from inner urban cities and junk yards to remote woodland swamps. In addition to maintaining equipment, each summer he would supervise the training of seasonal research assistants in mosquito

This is also the first report of S. mycoparasitica as a biotrophic mycoparasite on Fusarium culmorum and F. equiseti in addition to its other reported hosts (F. avenaceum, F. graminearum, and F. oxysporum). In slide culture assays, S. mycoparasitica acted as a contact mycoparasite of F. culmorum, and F. equiseti producing hook-like attachment structures. Fluorescent and confocal laser scanning microscopy showed that S. mycoparasitica is an intracellular mycoparasite of F. equiseti but not of F. culmorum. All three mycoparasitic Sphaerodes species were observed to produce asexual (anamorphic) stages when challenged with Fusarium. Furthermore, a phylogenetic tree, based on (large subunit) LSU rDNA sequences, depicted closer relatedness to one another of these Fusarium-specific Sphaerodes taxa than to the non- mycoparasitic S. compressa, S. fimicola, and S. singaporensis. Key words — ascomycete, coevolution Introduction Mycoparasitism refers to the parasitic interactions between one fungus (parasite) and another fungus (host). These relationships can be categorized as either necrotrophic or biotrophic (Boosalis 1964; Butler 1957).

  • Discovery of the Teleomorph of the Hyphomycete, Sterigmatobotrys Macrocarpa, and Epitypification of the Genus to Holomorphic Status
    available online at www.studiesinmycology.org StudieS in Mycology 68: 193–202. 2011. doi:10.3114/sim.2011.68.08 Discovery of the teleomorph of the hyphomycete, Sterigmatobotrys macrocarpa, and epitypification of the genus to holomorphic status M. Réblová1* and K.A. Seifert2 1Department of Taxonomy, Institute of Botany of the Academy of Sciences, CZ – 252 43, Průhonice, Czech Republic; 2Biodiversity (Mycology and Botany), Agriculture and Agri- Food Canada, Ottawa, Ontario, K1A 0C6, Canada *Correspondence: Martina Réblová, [email protected] Abstract: Sterigmatobotrys macrocarpa is a conspicuous, lignicolous, dematiaceous hyphomycete with macronematous, penicillate conidiophores with branches or metulae arising from the apex of the stipe, terminating with cylindrical, elongated conidiogenous cells producing conidia in a holoblastic manner. The discovery of its teleomorph is documented here based on perithecial ascomata associated with fertile conidiophores of S. macrocarpa on a specimen collected in the Czech Republic; an identical anamorph developed from ascospores isolated in axenic culture. The teleomorph is morphologically similar to species of the genera Carpoligna and Chaetosphaeria, especially in its nonstromatic perithecia, hyaline, cylindrical to fusiform ascospores, unitunicate asci with a distinct apical annulus, and tapering paraphyses. Identical perithecia were later observed on a herbarium specimen of S. macrocarpa originating in New Zealand. Sterigmatobotrys includes two species, S. macrocarpa, a taxonomic synonym of the type species, S. elata, and S. uniseptata. Because no teleomorph was described in the protologue of Sterigmatobotrys, we apply Article 59.7 of the International Code of Botanical Nomenclature. We epitypify (teleotypify) both Sterigmatobotrys elata and S. macrocarpa to give the genus holomorphic status, and the name S.

Phylogenetic analyses of combined LSU, SSU and RPB2 sequence data place these hitherto unidentified taxa close to Ascotaiwania and Bactrodesmiastrum. Arobust clade containing anew combination Pseudoascotaiwania persoonii, Bactrodesmiastrum species, Plagiascoma frondosum and three new species, are introduced in the new order Fuscosporellales (Hypocreomycetidae, Sordariomycetes). A sister relationship for Fuscosporellales with Conioscyphales, Pleurotheciales and Savoryellales is strongly supported by sequence data. Taxonomic novelties introduced in Fuscosporellales are four monotypic genera, viz. Fuscosporella, Mucispora, Parafuscosporella and Pseudoascotaiwania.Anew taxon in its asexual morph is proposed in Ascotaiwania based on molecular data and cultural characters.

Changes in maize genetics (G) and environmental (E) conditions increased productivity under high-synthetic- input conditions. However, novel selective pressures on the rhizobiome may have incurred undesirable trade- offs in organic agroecosystems, where plants obtain nutrients via microbially mediated processes including mineralization of organic matter. Using twelve maize genotypes representing an evolutionary transect (teosintes, landraces, inbred parents of modern elite germplasm, and modern hybrids) and two agricultural soils with contrasting long- term management, we integrated analyses of rhizobiome community structure, potential microbe-microbe interactions, and N-cycling functional genes to better understand the impacts of maize evo- lution and soil management legacy on rhizobiome recruitment.

Four data sets were analysed: a) the internal transcribed spacer region including ITS1, 5.8S rDNA and ITS2 (ITS), b) nc28S (ncLSU) rDNA, c) nc18S (ncSSU) rDNA, and d) a combined data set of ncLSU-ncSSU-RPB2 (ribosomal polymerase B2). The traditional placement of Ch. tulasneorum in the Microascales based on ncLSU sequences is unsupported and Australiasca does not belong to the Chaetosphaeriaceae. Both holomorph species are nested within the Glomerellales. A new genus, Reticulascus, is introduced for Ch. tulasneorum with associated Cylindrotrichum anamorph; another species of Reticulascus and its anamorph in Cylindrotrichum are described as new. The taxonomic structure of the Glomerellales is clarified and the name is validly published. As delimited here, it includes three families, the Glomerellaceae and the newly described Australiascaceae and Reticulascaceae. Based on ITS and ncLSU rDNA sequence analyses, we confirm the synonymy of the anamorph generaDischloridium with Monilochaetes.

  • First Record of Melanospora Chionea As a Possible Cause of Pink Root Rot Disease on Tomato Plants in Egypt
    atholog P y & nt a M l i P c f r o o b l i o a n l Journal of Plant Pathology & o r g u y o J ISSN: 2157-7471 Microbiology Research Article First Record of Melanospora chionea as a Possible Cause of Pink Root Rot Disease on Tomato Plants in Egypt Farag MF* Plant Pathology Research Institute, Agricultural Research Center, Giza, Egypt ABSTRACT Tomato is one of the most important vegetable crops in the world. It is infected with several disease through the growth season, but new disease appeared as a new challenge to tomato productivity, causing pink root rot. Symptoms of pink root rot were observed on tomato (Lycopersicon esculentum Mill.) grown in Beni Sweif Governorate (Nasser, Sumosta, Beba and El-Wasta Counties) in summer 2013 as poor growth, chlorosis and then necrosis of the tip branches, by maturity. Typical symptoms on the infected root especially, epidermis were picked areas and both of cortex and vascular bundles were colored with pink along the infected tissues consistent with both those that were observed in the field. Based on morphological characteristics of the isolated fungus, disease symptoms and a pathogenicity test, Melanospora chionea was identified as the causal agent of pink root rot of tomato. Identification of this species was confirmed by sequencing of internal transcribed space (ITS region) of ribosomal RNA gene. M. chionea has not previously been reported on tomato. The host range of this disease was defined between numerous hosts belonging to Fabaceae, Malvaceae, Cucurbitaceae and Solanaceae. The aim of this work to determine and description of the disease and identification of the pathogen morphologicaly and genetically.

Réblová1, J. Fournier 2, V. Štěpánek3 Key words Abstract Four morphologically similar specimens of an unidentified perithecial ascomycete were collected on decaying wood submerged in fresh water. Phylogenetic analysis of DNA sequences from protein-coding and Achroceratosphaeria ribosomal nuclear loci supports the placement of the unidentified fungus together with Achroceratosphaeria in a freshwater strongly supported monophyletic clade. The four collections are described as two new species of the new genus Hypocreomycetidae Pisorisporium characterised by non-stromatic, black, immersed to superficial perithecial ascomata, persistent para- Koralionastetales physes, unitunicate, persistent asci with an amyloid apical annulus and hyaline, fusiform, cymbiform to cylindrical, Lulworthiales transversely multiseptate ascospores with conspicuous guttules. The asexual morph is unknown and no conidia multigene analysis were formed in vitro or on the natural substratum. The clade containing Achroceratosphaeria and Pisorisporium is systematics introduced as the new order Pisorisporiales, family Pisorisporiaceae in the class Sordariomycetes. It represents a new lineage of aquatic fungi. A sister relationship for Pisorisporiales with the Lulworthiales and Koralionastetales is weakly supported

Phylogenetic analyses of DNA sequences of two ribosomal nuclear loci of the above taxa and those previous recognized as the TBM clade suggest that they form a distinct clade amongst the Hypocreales, Microascales, Savoryellales, Coronophorales and Melanosporales in the Hypocreomycetidae. Four well-supported subclades in the “TBM clade” are discerned including: 1) the Juncigena subclade, 2) the Etheirophora and Swampomyces s. s. subclade, 3) the Falcocladium subclade and 4) the Torpedospora subclade. Chaetosphaeria chaetosa does not group in the Chaetosphaeriales but together with Swampomyces aegyptiacus and S.
