Mycosphere 10(1), 757–775, Doi 10.5943/mycosphere/10/1/17 Abstract A new hyphomycete genus, Pleopunctum, is introduced to accommodate two new species, P. ellipsoideum sp. nov. (type species) and P. pseudoellipsoideum sp. nov., collected from decaying wood in Guizhou Province, China. The genus is characterized by macronematous, mononematous conidiophores, monoblastic conidiogenous cells and muriform, oval to ellipsoidal conidia often with a hyaline, elliptical to globose basal cell. Phylogenetic analyses of combined LSU, SSU, ITS and TEF1α sequence data of 55 taxa were carried out to infer their phylogenetic relationships. The new taxa formed a well-supported subclade in the family Phaeoseptaceae and basal to Lignosphaeria and Thyridaria macrostomoides. -

Biocontrol of Stemphylium Vesicarium and Pleospora Allii on Pear by Bacillus Subtilis and Trichoderma Spp.: Preventative and Curative Effects on Inoculum Production
agronomy Article Biocontrol of Stemphylium vesicarium and Pleospora allii on Pear by Bacillus subtilis and Trichoderma spp.: Preventative and Curative Effects on Inoculum Production Concepció Moragrega , Alba Carmona and Isidre Llorente * Laboratory of Plant Pathology, Institute of Food and Agricultural Technology-XaRTA-CIDSAV, University of Girona, 17003 Girona, Spain; [email protected] (C.M.); [email protected] (A.C.) * Correspondence: [email protected] Abstract: Trials under controlled and field conditions were conducted to establish the effect of strategies of application of biological control agents (BCAs) in the reduction of Stemphylium vesicarium and Pleospora allii inoculum production on pear leaf debris. Six BCAs based on different strains of Trichoderma spp. (Tr1, Tr2) and Bacillus subtilis (Bs1, Bs2, Bs3 and Bs4) were evaluated. Two strategies were tested in controlled experiments: application before (preventative strategy) or after (curative strategy) pear leaf debris colonization by S. vesicarium, evaluating the growth inhibition and sporulation of S. vesicarium and the pseudothecia production of P. allii. When the BCAs were applied preventatively, the efficacy of treatments based on B. subtilis was higher than those based on Trichoderma spp. in controlling the pathogen colonization, but that of controlling the inoculum Citation: Moragrega, C.; production of S. vesicarium and P. allii was similar. However, when the BCAs were applied curatively, Carmona, A.; Llorente, I. Biocontrol Trichoderma based products were more effective. In field trials, Trichoderma spp. Tr1 and B. subtlilis of Stemphylium vesicarium and Bs1 produced a consistent 45–50% decrease in the number of S. vesicarium conidia trapped compared Pleospora allii on Pear by Bacillus to the non-treated control. -

Extension Plant Pathology Update July 2013
Extension Plant Pathology Update July 2013 Volume 1, Number 6 Edited by Jean Williams-Woodward Plant Disease Clinic Report for June 2013 By Ansuya Jogi and Jean Williams-Woodward The following tables consist of the commercial and homeowner samples submitted to the UGA plant disease clinics in Athens and Tifton for June 2013 (Table 1) and for one year ago in July 2012 (Table 2). The wet weather has been great for plant growth, as well as plant diseases. Various root rots, leaf spots and rusts have been diagnosed on almost all crops. The incidence of bacterial diseases will increase through July, as will Sclerotium rolfsii and Rhizoctonia diseases. We also continue to confirm Rose Rosette-associated virus on Knock-Out rose samples. Also, Dr. Little has confirmed Cucurbit Yellow Vine Disease on squash, caused by the bacterium, Serratia marcescens. She has a graduate student working on this disease and wants to know if you are seeing it. See page 7 for her summary of cucurbit diseases, including cucurbit yellow vine disease. Looking ahead with the current weather pattern, we expect to see more leaf and root diseases on all crops. This isn’t a surprise. Warm days, cooler nights, high humidity, wet foliage and saturated soils are the recipe for plant disease development. Again, it is an exciting time to be a plant pathologist.

Gareth Jones, [email protected] Abstract: Phylogenetic analyses of four nuclear genes, namely the large and small subunits of the nuclear ribosomal RNA, transcription elongation factor 1-alpha and the second largest RNA polymerase II subunit, established that the ecological group of marine bitunicate ascomycetes has representatives in the orders Capnodiales, Hysteriales, Jahnulales, Mytilinidiales, Patellariales and Pleosporales. Most of the fungi sequenced were intertidal mangrove taxa and belong to members of 12 families in the Pleosporales: Aigialaceae, Didymellaceae, Leptosphaeriaceae, Lenthitheciaceae, Lophiostomataceae, Massarinaceae, Montagnulaceae, Morosphaeriaceae, Phaeosphaeriaceae, Pleosporaceae, Testudinaceae and Trematosphaeriaceae. Two new families are described: Aigialaceae and Morosphaeriaceae, and three new genera proposed: Halomassarina, Morosphaeria and Rimora. -

Faris Dr. Phillip E. McClean Dr. Timothy L. Friesen Approved: November 7, 2018 Jack Rasmussen Date Department Chair ABSTRACT Tan spot of wheat, caused by Pyrenophora tritici-repentis, is an economically important disease worldwide. The disease system is known to involve three pairs of interactions between fungal-produced necrotrophic effectors (NEs) and the wheat sensitivity genes, namely Ptr ToxA- Tsn1, Ptr ToxB-Tsc2 and Ptr ToxC-Tsc1, all of which result in susceptibility. Many lines of evidence also suggested the involvement of additional fungal virulence and host resistance factors. Due to the non-proteinaceous nature, Ptr ToxC, has not been purified and the fungal gene (s) controlling Ptr ToxC production is unknown. The objective for the first part of research is to map the fungal gene (s) controlling Ptr ToxC production. Therefore, A bi-parental fungal population segregating for Ptr ToxC production was first developed from genetically modified heterothallic strains of AR CrossB10 (Ptr ToxC producer) and 86-124 (Ptr ToxC non-producer), and then was genotyped and phenotyped. -
9B Taxonomy to Genus
Fungus and Lichen Genera in the NEMF Database Taxonomic hierarchy: phyllum > class (-etes) > order (-ales) > family (-ceae) > genus. Total number of genera in the database: 526 Anamorphic fungi (see p. 4), which are disseminated by propagules not formed from cells where meiosis has occurred, are presently not grouped by class, order, etc. Most propagules can be referred to as "conidia," but some are derived from unspecialized vegetative mycelium. A significant number are correlated with fungal states that produce spores derived from cells where meiosis has, or is assumed to have, occurred. These are, where known, members of the ascomycetes or basidiomycetes. However, in many cases, they are still undescribed, unrecognized or poorly known. (Explanation paraphrased from "Dictionary of the Fungi, 9th Edition.") Principal authority for this taxonomy is the Dictionary of the Fungi and its online database, www.indexfungorum.org. For lichens, see Lecanoromycetes on p. 3.
