Buckeye rot of tomato caused by Phytophthora nicotianae var. parasitica is a serious threat to the crop production and has taken a heavy toll of the crop in India which affects mostly the fruits during both spring and winter season crops. In the present investigation, six biological control agents were screened for the efficacy against mycelial growth of P. nicotianae var. parasitica. Out of the six fungal and bacterial biocontrol agents tested, Trichoderma virens resulted in maximum mycelial growth inhibition (77.67%) of the test pathogen followed by T. hamatum (69.40 %), T. harzianum (68.52 %) and T. viride (67.43 %). -

T. Nguyen and Hyang Burm Lee* 5 Division of Food Technology, Biotechnology and Agrochemistry, College of Agriculture and Life Sciences, 6 Chonnam National University, Gwangju 61186, Korea; [email protected] (S.H.L.); 7 [email protected] (T.T.T.N.) 8 * Correspondence: [email protected]; Tel.: +82-(0)62-530-2136 9 10 Abstract: The order Mucorales, the largest in number of species within the Mucoromycotina, 11 comprises typically fast-growing saprotrophic fungi. During a study of the fungal diversity of 12 undiscovered taxa in Korea, two mucoralean strains, CNUFC-GWD3-9 and CNUFC-EGF1-4, were 13 isolated from specific habitats including freshwater and fecal samples, respectively, in Korea. The 14 strains were analyzed both for morphology and phylogeny based on the internal transcribed 15 spacer (ITS) and large subunit (LSU) of 28S ribosomal DNA regions. On the basis of their 16 morphological characteristics and sequence analyses, isolates CNUFC-GWD3-9 and CNUFC- 17 EGF1-4 were confirmed to be Gilbertella persicaria and Pilobolus crystallinus, respectively.To the 18 best of our knowledge, there are no published literature records of these two genera in Korea. 19 Keywords: Gilbertella persicaria; Pilobolus crystallinus; mucoralean fungi; phylogeny; morphology; 20 undiscovered taxa 21 22 1. Introduction 23 Previously, taxa of the former phylum Zygomycota were distributed among the phylum 24 Glomeromycota and four subphyla incertae sedis, including Mucoromycotina, Kickxellomycotina, 25 Zoopagomycotina, and Entomophthoromycotina [1]. -
Molecular Phylogenetic and Scanning Electron Microscopical Analyses

OLSSON2 1 Institut für Mikrobiologie, Pilz-Referenz-Zentrum, Friedrich-Schiller-Universität Jena, Neugasse 24, D-07743 Jena, Germany 2 Institut für Spezielle Zoologie und Evolutionsbiologie, Friedrich-Schiller-Universität Jena, Erbertstr. 1, D-07743 Jena, Germany (Received: May 4, 2007; accepted: June 11, 2007) A multi-gene genealogy based on maximum parsimony and distance analyses of the exonic genes for actin (act) and translation elongation factor 1 alpha (tef ), the nuclear genes for the small (18S) and large (28S) subunit ribosomal RNA (comprising 807, 1092, 1863, 389 characters, respectively) of all 50 gen- era of the Mucorales (Zygomycetes) suggests that the Choanephoraceae is a monophyletic group. The monotypic Gilbertellaceae appears in close phylogenetic relatedness to the Choanephoraceae. The mono- phyly of the Choanephoraceae has moderate to strong support (bootstrap proportions 67% and 96% in distance and maximum parsimony analyses, respectively), whereas the monophyly of the Choanephoraceae-Gilbertellaceae clade is supported by high bootstrap values (100% and 98%). This suggests that the two families can be joined into one family, which leads to the elimination of the Gilbertellaceae as a separate family. In order to test this hypothesis single-locus neighbor-joining analy- ses were performed on nuclear genes of the 18S, 5.8S, 28S and internal transcribed spacer (ITS) 1 ribo- somal RNA and the translation elongation factor 1 alpha (tef ) and beta tubulin (βtub) nucleotide sequences. -

Disease Update
Disease Update The Long List of Diseases Affecting Tomatoes and Peppers in a Wet Growing Season By Thomas A. Zitter Cornell University (May 2001) Introduction The 2000 growing season will be remembered for the large number of diseases that could be found on both tomatoes and peppers. Some of these diseases are common to both crops, and include bacterial leaf spot, Phytophthora blight, and white mold. In this report, we will focus on the main fungal (late blight, early blight, Septoria leaf blight, Phytophthora blight), and bacterial (spot, speck and canker) diseases of tomato/pepper. Tomato Late Blight Tomato growers should be aware that late blight infections of this crop are not new in New York, but occurrence of the disease has definitely increased during the 1990s with the arrival of new immigrant strains of Phytophthora infestans. In 1993, U.S.-7 caused widespread losses in home gardens in rural upstate New York, with the disease eventually spreading into four counties (Oneida, Herkimer, Madison and Oswego). In 1996, late blight samples confirmed in the Plant Disease Diagnostic Lab were submitted from six counties (Chautaupqua, Ontario, Tioga, Orange, Schenectady and Clinton), consisting of U.S.-1, U.S.-8 and U.S.-17. Once again, the infections for the most part were limited to home gardens or tomato plantings used for nearby roadside stands. In 1997, both commercial and homeowners suffered the greatest losses to late blight previously recorded. Tomato late blight was verified by the Diagnostic Lab from samples submitted from 12 counties from western, central and eastern New York. -

1 the SOCIETY LIBRARY CATALOGUE the BMS Council
THE SOCIETY LIBRARY CATALOGUE The BMS Council agreed, many years ago, to expand the Society's collection of books and develop it into a Library, in order to make it freely available to members. The books were originally housed at the (then) Commonwealth Mycological Institute and from 1990 - 2006 at the Herbarium, then in the Jodrell Laboratory,Royal Botanic Gardens Kew, by invitation of the Keeper. The Library now comprises over 1100 items. Development of the Library has depended largely on the generosity of members. Many offers of books and monographs, particularly important taxonomic works, and gifts of money to purchase items, are gratefully acknowledged. The rules for the loan of books are as follows: Books may be borrowed at the discretion of the Librarian and requests should be made, preferably by post or e-mail and stating whether a BMS member, to: The Librarian, British Mycological Society, Jodrell Laboratory Royal Botanic Gardens, Kew, Richmond, Surrey TW9 3AB Email: <[email protected]> No more than two volumes may be borrowed at one time, for a period of up to one month, by which time books must be returned or the loan renewed. The borrower will be held liable for the cost of replacement of books that are lost or not returned. BMS Members do not have to pay postage for the outward journey. For the return journey, books must be returned securely packed and postage paid. Non-members may be able to borrow books at the discretion of the Librarian, but all postage costs must be paid by the borrower. -
