  • Diversity and Distribution of Polyporales in Peninsular Malaysia (Kepelbagaian Dan Taburan Polyporales Di Semenanjung Malaysia)
    Sains Malaysiana 41(2)(2012): 155–161 Diversity and Distribution of Polyporales in Peninsular Malaysia (Kepelbagaian dan Taburan Polyporales di Semenanjung Malaysia) MOHAMAD HASNUL BOLHASSAN, NOORLIDAH ABDULLAH*, VIKINESWARY SABARATNAM, HATTORI TSUTOMU, SUMAIYAH ABDULLAH, NORASWATI MOHD. NOOR RASHID & MD. YUSOFF MUSA ABSTRACT Macrofungi of the order Polyporales are among the most important wood decomposers and caused economic losses by decaying the wood in standing trees, logs and in sawn timber. Diversity and distribution of Polyporales in Peninsular Malaysia was investigated by collecting basidiocarps from trunks, branches, exposed roots and soil from six states (Johor, Kedah, Kelantan, Negeri Sembilan, Pahang and Selangor) in Peninsular Malaysia and Federal Territory Kuala Lumpur. This study showed that the diversity of Polyporales were less diverse than previously reported. The study identified 60 species from five families; Fomitopsidaceae, Ganodermataceae, Meruliaceae, Meripilaceae, and Polyporaceae. The common species of Polyporales collected were Fomitopsis feei, Amauroderma subrugosum, Ganoderma australe, Earliella scabrosa, Lentinus squarrosulus, Microporus xanthopus, Pycnoporus sanguineus and Trametes menziesii.

    DIVERSITY OF POLYPORALES AND THE APPLICATION OF GANODERMA AUSTRALE (FR.) PAT. IN BIOPULPING OF EMPTY FRUIT BUNCHES OF ELAEIS GUINEENSIS MOHAMAD HASNUL BIN BOLHASSAN THESIS SUBMITTED IN FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY FACULTY OF SCIENCE UNIVERSITY OF MALAYA KUALA LUMPUR 2012 ABSTRACT Diversity and distribution of Polyporales in Malaysia was investigated by collecting basidiocarps from trunks, branches, exposed roots and soil from six states (Johore, Kedah, Kelantan, Negeri Sembilan, Pahang and Selangor) in Peninsular Malaysia and Federal Territory Kuala Lumpur. The morphological study of 99 basidiomata collected from 2006 till 2007 and 241 herbarium specimens collected from 2003 - 2005 were undertaken. Sixty species belonging to five families: Fomitopsidaceae, Ganodermataceae, Meruliaceae, Meripilaceae and Polyporaceae were recorded. Polyporaceae was the dominant family with 46 species identified. The common species encountered based on the number of basidiocarps collected were Ganoderma australe followed by Lentinus squarrosulus, Earliella scabrosa, Pycnoporus sanguineus, Lentinus connatus, Microporus xanthopus, Trametes menziesii, Lenzites elegans, Lentinus sajor-caju and Microporus affinis. Eighteen genera with only one specie were also recorded i.e. Daedalea, Amauroderma, Flavodon, Earliella, Echinochaetae, Favolus, Flabellophora, Fomitella, Funalia, Hexagonia, Lignosus, Macrohyporia, Microporellus, Nigroporus, Panus, Perenniporia, Pseudofavolus and Pyrofomes. This study shows that strains of the G. lucidum and G. australe can be identified by 650 base pair nucleic acid sequence characters from ITS1, 5.8S rDNA and ITS2 region on the ribosomal DNA. The phylogenetic analysis used maximum-parsimony as the optimality criterion and heuristic searches used 100 replicates of random addition sequences with tree-bisection-reconnection (TBR) branch-swaping. ITS phylogeny confirms that G.

  • Rigidoporus Microporus During Saprotrophic Growth on Rubber Wood Abbot O
    Oghenekaro et al. BMC Genomics (2016) 17:234 DOI 10.1186/s12864-016-2574-9 RESEARCH ARTICLE Open Access De novo transcriptomic assembly and profiling of Rigidoporus microporus during saprotrophic growth on rubber wood Abbot O. Oghenekaro*, Tommaso Raffaello, Andriy Kovalchuk and Fred O. Asiegbu Abstract Background: The basidiomycete Rigidoporus microporus isafungusthatcausesthewhiterotdiseaseofthe tropical rubber tree, Hevea brasiliensis, the major source of commercial natural rubber. Besides its lifestyle as a pathogen,thefungusisknowntoswitchtosaprotrophicgrowthonwoodwiththeabilitytodegradeboth lignin and cellulose. There is almost no genomic or transcriptomic information on the saprotrophic abilities of this fungus. In this study, we present the fungal transcriptomic profiles during saprotrophic growth on rubber wood. Results: A total of 266.6 million RNA-Seq reads were generated from six libraries of the fungus growing either onrubberwoodorwithoutwood.De novo assembly produced 34, 518 unigenes with an average length of 2179 bp. Annotation of unigenes using public databases; GenBank, Swiss-Prot, Kyoto Encyclopedia of Genes and Genomes (KEGG), Cluster of Orthologous Groups (COG) and Gene Ontology (GO) produced 25, 880 annotated unigenes. Transcriptomic profiling analysis revealed that the fungus expressed over 300 genes encoding lignocellulolytic enzymes. Among these, 175 genes were up-regulated in rubber wood. These include three members of the glycoside hydrolase family 43, as well as various glycosyl transferases, carbohydrate esterases and polysaccharide lyases. A large number of oxidoreductases which includes nine manganese peroxidases were also significantly up-regulated in rubber wood. Several genes involved in fatty acid metabolism and degradation as well as natural rubber degradation were expressed in the transcriptome. Four genes (acyl-CoA synthetase, enoyl-CoA hydratase, 3-hydroxyacyl-CoA dehydrogenase and acyl-CoA acetyltransferase) potentially involved in rubber latex degradation pathway were also induced.

Asiegbu2* Fungal plant pathogens remain a serious threat to the sustainable agriculture and forestry, despite the extensive eforts undertaken to control their spread. White root rot disease is threatening rubber tree (Hevea brasiliensis) plantations throughout South and Southeast Asia and Western Africa, causing tree mortality and severe yield losses. Here, we report the complete genome sequence of the basidiomycete fungus Rigidoporus microporus, a causative agent of the disease. Our phylogenetic analysis confrmed the position of R. microporus among the members of Hymenochaetales, an understudied group of basidiomycetes. Our analysis further identifed pathogen’s genes with a predicted role in the decay of plant cell wall polymers, in the utilization of latex components and in interspecifc interactions between the pathogen and other fungi. We also detected putative horizontal gene transfer events in the genome of R. microporus. The reported frst genome sequence of a tropical rubber tree pathogen R. microporus should contribute to the better understanding of how the fungus is able to facilitate wood decay and nutrient cycling as well as tolerate latex and utilize resinous extractives.

    Session III – Forest and Natural Resource Management 315 Isolation of Rigidoporus microporus , the Cause of WRD of Rubber, from Some Forest Associated Plants Madushani H.K.I. 1, Fernando T.H.P.S. 1*, Wijesundara R.L.C. 2 and Siriwardane D. 1 1Department of Plant Pathology, Rubber Research Institute of Sri Lanka, Agalawatta, Sri Lanka 2Department of Plant Science, Faculty of Science, University of Colombo, Colombo 03, Sri Lanka *[email protected] Abstract Natural rubber while promoting export earnings and livelihood of people supplement thousands of hectares to the forest cover. Over the past decades, the rubber yield has significantly increased due to the cultivation of high yielding clones. However, latex production still faces serious economic losses due to many biotic constraints which include significant losses caused by pathogenic fungi. Among them, White root disease (WRD) is very destructive in rubber plantations of Sri Lanka and in many other rubber growing countries. This disease has been identified as one of the major causes for the loss of plants during the first five years after planting resulting in low productivity levels. Inspite of the fact that disease management strategies have been clearly outlined by the Rubber Research Institute, the disease incidence is showing an increasing trend. One of the main reasons for this has been identified as the increment of the host range. In this situation expansion of the host range of R.micrporus was undertaken. R. microporus was isolated from the symptomatic host plants such as Mucuna bractiacta , Camellia sinensis, Cinnamomum zeylanicum, Artocarpus nobilis, Alstonia macrophyll growing in and around rubber plantations.

  • Effect of Selected Microenvironmental Factors on Colony Growth And
    Tropical Agricultural Research Vol. 30 (4): 105 – 116 (2018) Effect of Selected Microenvironmental Factors on Colony Growth and Cross Infectional Ability of Fungal Pathogens Causing Root Rot Disease of Jak (Artocarpus heterophillus ) M. Kuruppu, D. M. De. Costa 1* and T.H.P.S. Fernando 2 Fruit Research and Development Institute Horana, Sri Lanka ABSTRACT : Root diseases have become an emerging biotic threat to Jak (A. heterophillus), grown in Sri Lanka. Isolation of the causal agents, identification and determination of the effect of selected microenvironmental factors and the cross- infection ability of the causal agents on other perennial crops towards development of effective management measures were the objectives of the present study. Two Rigidoporous microspores isolates and a Fusarium oxysporum and a F. solani isolate were identified as causal agents of root rot disease of Jak. Colony growth of the two R. microsporus isolates and the Fusarium isolates responded differently to pH, temperature and light intensity. Differences of colony growth responses were identified even between the two isolates of R. microporus. Among the perennial tree species used, Atocarpus nobilis was highly susceptible to all four fungal isolates and the lowest infection ability was shown on Persea americana. Artocarpus altilis (Rata Del), Hevea brasiliensis (Rubber), Cinnammomum zeylanicum (Cinnamon), Durio zibethinus (Durian), Psidium guajava (Guvava) and Nephellium lapaceum (Rambutan)were equally-susceptible to the infection by the four fungal isolates, used. Findings of the study are informative when developing an integrated management programme against root diseases of Jak. Keywords: Colony growth response, Fusarium oxysporum, Fusarium solani, Rigidoporus microporus INTRODUCTION Jak ( Artocarpus heterophillus ), belonging to Family Moraceae, is an economically versatile tropical tree crop, providing food, timber, fuel, fodder and medicinal and industrial products.

Current Research in Environmental & Applied Mycology (Journal of Fungal Biology) 10(1), 475–493, Doi 10.5943/cream/10/1/37 Abstract This study was conducted to determine the different macroscopic fungi present in the Bugkalot tribal community in Alfonso Castañeda, Nueva Vizcaya, Philippines. A total of 45 macrofungi belonging to 6 orders, 15 families and 25 genera was collected, identified and described in the taxonomic checklist. Twenty-five species were able to identify up to species level. Most of the macrofungi are wood-rotters. Family Polyporaceae was recorded as the most abundant macrofungi family present in the area. Out of all macrofungi, 25 species were used by the Bugkalots as either as food or medicine. The Bugkalot tribal community in Alfonso Castañeda, Nueva Vizcaya is a habitat for the different macrofungal species. Thus, further studies should be done on other season to determine the species richness and distribution of macrofungi in the community.
