Sugarcane Wilt: New Insights Into Pathogen Identity, Variability and Pathogenicity
® Functional Plant Science and Biotechnology ©2012 Global Science Books Sugarcane Wilt: New Insights into Pathogen Identity, Variability and Pathogenicity Rasappa Viswanathan* • Muthusamy Poongothai • Palaniyandi Malathi • Amalraj R. Sundar Sugarcane Breeding Institute, Indian Council of Agricultural Research, Coimbatore 641007, India Corresponding author : * [email protected] ABSTRACT Wilt of sugarcane, a fungal disease is known to cause significant damage to sugarcane production and productivity in India and other countries for the past one century. Although sugarcane wilt is known in India for a long time, research work on this important disease is totally lacking. The causal organism was found to vary with time and investigator and could not reproduce the disease under artificial conditions in the field. We have made detailed disease surveys in 13 major sugarcane growing states in the country and 263 Fusarium isolates were isolated. We have established the variation in Fusarium isolates associated with sugarcane wilt, based on cultural, morphological, pathogenic and molecular characterization of 117 isolates. Critical observations in the conventional techniques combined with molecular biological approaches clearly established that Fusarium sacchari as the causal agent of the disease. Other Fusarium sp isolated from wilt infected sugarcane stalks were found to be either secondary invaders or non-pathogenic in nature. We have developed an artificial simulation technique to induce wilt in sugarcane under field conditions and -

Julio Herrera y Reissig 565,Montevideo,Uruguay Résumé – L’analyse des communautés de champignons provenant des composts préparés avec différentes matières premières a été menée pour évaluer l’abondance et la fréquence des espèces qui pourraient constituer un risque pour les plantes, les animaux ou la santé humaine. Un total de 40 405 × 103 propagules correspondant à 90 espèces a été dénombré dans 30 échantillons de deux composts de composition différente. Douze de ces espèces sont thermo-tolérantes, trois sont thermophiles et les autres sont des espèces mésophiles. Acrodontium crateriforme, est l’espèce la plus abondante, présente dans presque la moitié des échantillons de compost préparé principalement à partir de déchets de poils de l’industrie du cuir. D’autres espèces, Aspergillus spp, Monocillium mucidum, Penicillium spp. Paecilomyces variotii, Candida sp. et Humicola grisea var. thermoidea étaient aussi présentes. Le compost composé de déchets de Ligustrum et d’écorces de riz mélangés avec des déjections de poulets est caractérisé par la présence de Aspergillus fumigatus, espèce présente dans presque tous les échantillons, et par Penicillium spp., Fusarium spp., Emericella nidulans, Emericella rugulosa et Humicola fuscoatra. Toutes ces espèces ont été mentionnées dans d’autres composts de différentes origines. Plusieurs d’entre elles sont importantes dans la biodégradation et d’autres sont des antagonistes vis-à-vis des agents pathogènes. Les deux composts peuvent être utilisés séparément ou ensembles pour améliorer la nutrition du sol et participer à la lutte biologique. -

On the basis of an ITS phylogeny, the authors question the monophyletic nature of family Elaphomycetaceae and of the genus Elaphomyces. The objective of this preliminary paper was not to propose a new phylogeny for Elaphomyces, but rather to draw attention to the very high dissimilarity among ITS sequences for Elaphomyces and to the unfortunate choice of species to represent the genus in most previous phylogenetic publications on Elaphomycetaceae and other cleistothecial ascomycetes. Our study highlights the need for examining the monophyly of this family and to verify the systematic status of Pseudotulostoma as a separate genus for stipitate species. Furthermore, there is an urgent need for an in-depth morphological study, combined with molecular sequencing of the studied taxa, to point out the phylogenetically informative characters of the discussed taxa. -
Identification of the Barley Phyllosphere
IDENTIFICATION OF THE BARLEY PHYLLOSPHERE AND CHARACTERISATION OF MANIPULATION MEANS OF THE BACTERIOME AGAINST LEAF SCALD AND POWDERY MILDEW CLEMENT GRAVOUIL, BSc, MSc Thesis submitted to the University of Nottingham for the degree of Doctor of Philosophy JULY 2012 ABSTRACT In the context of increasing food insecurity, new integrated and more sustainable crop protection methods need to be developed. The phyllosphere, i.e. the leaf habitat, hosts a considerable number of microorganisms. However, only a limited number of these are pathogenic and the roles of the vast majority still remain unknown. Managing the leaf-associated microbial communities is emerging as a potential integrated crop protection strategy. This thesis reports the characterisation of the phyllosphere of barley, an economically important crop in Scotland, with the purpose of developing tools to manipulate it. Field experiments were carried out to determine the composition of the culturable bacterial phyllosphere. The leaf-associated populations were demonstrated to be dominated by bacteria belonging to the Pseudomonas genus. Two bacterial isolates, Pseudomonas syringae and Pectobacterium atrosepticum, hindered the growth of Rhynchosporium commune, the causal agent of the leaf scald, but promoted the development of powdery mildew symptoms, caused by Blumeria graminis f.sp. hordei. However, using a molecular fingerprinting technique, namely T-RFLP, the global community was shown to be significantly richer and more diverse than indicated by the culture-based methods, thus increasing the complexity of interactions taking place in the phyllosphere. Various factors were found to affect the structure of the phyllobacteria significantly. Under controlled conditions, a root-associated symbiont, Piriformospora indica, was shown to increase the plant fitness and shift the abundance of the most common bacteria. -

Monograph on Dematiaceous Fungi
Monograph On Dematiaceous fungi A guide for description of dematiaceous fungi fungi of medical importance, diseases caused by them, diagnosis and treatment By Mohamed Refai and Heidy Abo El-Yazid Department of Microbiology, Faculty of Veterinary Medicine, Cairo University 2014 1 Preface The first time I saw cultures of dematiaceous fungi was in the laboratory of Prof. Seeliger in Bonn, 1962, when I attended a practical course on moulds for one week. Then I handled myself several cultures of black fungi, as contaminants in Mycology Laboratory of Prof. Rieth, 1963-1964, in Hamburg. When I visited Prof. DE Varies in Baarn, 1963. I was fascinated by the tremendous number of moulds in the Centraalbureau voor Schimmelcultures, Baarn, Netherlands. On the other hand, I was proud, that El-Sheikh Mahgoub, a Colleague from Sundan, wrote an internationally well-known book on mycetoma. I have never seen cases of dematiaceous fungal infections in Egypt, therefore, I was very happy, when I saw the collection of mycetoma cases reported in Egypt by the eminent Egyptian Mycologist, Prof. Dr Mohamed Taha, Zagazig University. To all these prominent mycologists I dedicate this monograph. Prof. Dr. Mohamed Refai, 1.5.2014 Heinz Seeliger Heinz Rieth Gerard de Vries, El-Sheikh Mahgoub Mohamed Taha 2 Contents 1.

Virtually all Fusarium species synthesize toxic secondary metabolites, known as mycotoxins; however, the roles of mycotoxins are not yet fully understood. To understand how a fungal partner alters its lifestyle to assimilate with the plant host remains a challenge. The review presented the mechanisms of mycotoxin biosynthesis in the Fusarium genus under various environmental conditions, such as pH, temperature, moisture content, and nitrogen source. It also concentrated on plant metabolic pathways and cytogenetic changes that are influenced as a consequence of mycotoxin confrontations. Moreover, we looked through special secondary metabolite production and mycotoxins specific for some significant fungal pathogens-plant host models. Plant strategies of avoiding the Fusarium mycotoxins were also discussed. Finally, we outlined the studies on the potential of plant secondary metabolites in defense reaction to Fusarium infection. Keywords: fungal pathogens; Fusarium; pathogenicity; secondary metabolites Key Contribution: The review summarized the knowledge and recent reports on the involvement of Fusarium mycotoxins in plant infection processes, as well as the consequences for plant metabolism and physiological changes related to the pathogenesis. -

Fungal brain Received: 10 Jan 2020 abscess often presents with subtle clinical symptoms and signs, and present diagnostic dilemma due to its imaging appearance that may be indistinguishable from other intracranial Accepted: 23 May 2020 space-occupying lesions. Still, certain imaging patterns on Computed Tomography (CT) and 01 Jul 2020 Available Online: Magnetic Resonance Imaging (MRI) help to narrow down the differential diagnosis and initiate prompt treatment of these infections. Case Presentation: A 48-year-old immunocompetent man presented with right-sided hemiparesis and hemisensory loss and a provisional diagnosis of stroke was made. The radiological evaluation suggested the possibility of a cerebral abscess. Accordingly, surgical excision of the lesion was performed and the histopathological examination of the specimen revealed the etiology as phaeohyphomycosis. The patient was further treated with antifungals and discharged when general conditions improved.
