Diseases of Rice Fungal Diseases Blast - Pyricularia oryzae (Syn: P. grisea) (Sexual stage: Magnaporthe grisea) Symptoms The fungus attacks the crop at all stages of crop growth. Symptoms appear on leaves, nodes, rachis, and glumes. On the leaves, the lesions appear as small bluish green flecks, which enlarge under moist weather to form the characteristic spindle shaped spots with grey centre and dark brown margin (Leaf blast). The spots coalesce as the disease progresses and large areas of the leaves dry up and wither. Spots also appear on sheath. Severely infected nursery and field appear as burnt. Black lesions appear on nodes girdling them. The affected nodes may break up and all the plant parts above the infected nodes may die (nodal blast).

  • Genetic and Pathogenic Differences Between Microdochium Nivale and Microdochium Majus
    Genetic and Pathogenic Differences Between Microdochium nivale and Microdochium majus by Linda Elizabeth Jewell A Thesis Presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Environmental Science Guelph, Ontario, Canada © Linda Elizabeth Jewell, December, 2013 ABSTRACT GENETIC AND PATHOGENIC DIFFERENCES BETWEEN MICRODOCHIUM NIVALE AND MICRODOCHIUM MAJUS Linda Elizabeth Jewell Advisor: University of Guelph, 2013 Professor Tom Hsiang Microdochium nivale and M. majus are fungal plant pathogens that cause cool-temperature diseases on grasses and cereals. Nucleotide sequences of four genetic regions were compared between isolates of M. nivale and M. majus from Triticum aestivum (wheat) collected in North America and Europe and for isolates of M. nivale from turfgrasses from both continents. Draft genome sequences were assembled for two isolates of M. majus and two of M. nivale from wheat and one from turfgrass. Dendograms constructed from these data resolved isolates of M. majus into separate clades by geographic origin. Among M. nivale, isolates were instead resolved by host plant species. Amplification of repetitive regions of DNA from M. nivale isolates collected from two proximate locations across three years grouped isolates by year, rather than by location. The mating-type (MAT1) and associated flanking genes of Microdochium were identified using the genome sequencing data to investigate the potential for these pathogens to produce ascospores. In all of the Microdochium genomes, and in all isolates assessed by PCR, only the MAT1-2-1 gene was identified. However, unpaired, single-conidium-derived colonies of M. majus produced fertile perithecia in the lab.

  • Wheat Blast Magnaporthe Oryzae (Catt.) (Synonym to Pyricularia Oryzae Cavara 1892)
    Wheat blast Magnaporthe oryzae (Catt.) (synonym to Pyricularia oryzae Cavara 1892) Taxonomy & Description Kingdom: Fungi Phylum: Ascomycota Class: Sordariomycetes Order: Magnaporthales Family: Magnaporthaceae Genus: Magnaporthe Species: Magnaporthe oryzae Kansas state university CIMMYT Field symptoms of wheat blast (Magnaporthe oryzae) Pathotypes: Pyricularia, the anamorphic name for the fungus, was established by Saccardo (1880) based on the pyriform shape of the asexual conidia of P. grisea on crabgrass. In 1892, Cavara designated rice isolates as P. oryzae. Sprague (1950) applied Pyricularia species names based on host, with P. oryzae for rice isolates and P. grisea for isolates from all other cereals and grasses. This back and forth for genus and species names explains why the rice and wheat blast pathogens are commonly referred to in the blast literature as Pyricularia or Magnaporthe, each with species identifiers of grisea or oryzae. Magnaporthe was chosen as the official name and Pyricularia as the synonym, and both names will continue to be used. There are a number of subpopulations or pathotypes within M. oryzae based on host they attack. There is the Oryza pathotype (MoO) specific to rice, the Triticum pathotype (MoT) specific to wheat, the Eleusine pathotype (MoE) specific to finger millet, Setaria pathotype (MoS) specific to foxtail millet and the Lolium pathotype (MoL) specific to turf grasses. The original rice blast disease caused by the MoO population appears to have arisen from a host jump from Setaria pathogens around the time rice was domesticated ~7000 years ago. The wheat pathogen in Brazil was originally suggested to have jumped from rice because blast was endemic in rice produced in northern Paraná state in 1985.

  • The Phylogeny of Plant and Animal Pathogens in the Ascomycota
    Physiological and Molecular Plant Pathology (2001) 59, 165±187 doi:10.1006/pmpp.2001.0355, available online at http://www.idealibrary.com on MINI-REVIEW The phylogeny of plant and animal pathogens in the Ascomycota MARY L. BERBEE* Department of Botany, University of British Columbia, 6270 University Blvd, Vancouver, BC V6T 1Z4, Canada (Accepted for publication August 2001) What makes a fungus pathogenic? In this review, phylogenetic inference is used to speculate on the evolution of plant and animal pathogens in the fungal Phylum Ascomycota. A phylogeny is presented using 297 18S ribosomal DNA sequences from GenBank and it is shown that most known plant pathogens are concentrated in four classes in the Ascomycota. Animal pathogens are also concentrated, but in two ascomycete classes that contain few, if any, plant pathogens. Rather than appearing as a constant character of a class, the ability to cause disease in plants and animals was gained and lost repeatedly. The genes that code for some traits involved in pathogenicity or virulence have been cloned and characterized, and so the evolutionary relationships of a few of the genes for enzymes and toxins known to play roles in diseases were explored. In general, these genes are too narrowly distributed and too recent in origin to explain the broad patterns of origin of pathogens. Co-evolution could potentially be part of an explanation for phylogenetic patterns of pathogenesis. Robust phylogenies not only of the fungi, but also of host plants and animals are becoming available, allowing for critical analysis of the nature of co-evolutionary warfare. Host animals, particularly human hosts have had little obvious eect on fungal evolution and most cases of fungal disease in humans appear to represent an evolutionary dead end for the fungus.

  • 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.

Two new species of Camarops (Boliniaceae, Ascomycotina) and a key to Argentinean species. - Sydowia 57 (1): 3-18. Four species of Camarops growing on Podocarpus parlatorei were collected in Argentina. Two of them, C. sacciformis and C. podocarpi, are undescribed species and the other two {C.pugillus and C.lutea) are new records for Argentina. A dichotomous key to the six species so far known from Argentina is provided. Keywords: Camarops, Podocarpus, Argentina, systematics. The genus Camarops P. Karst. (Boliniaceae Rick) presently includes fourteen species (Kirk & al., 2001), which have been described and reported by Shear (1938, 1940), Nannfeldt (1972), Hilber & Hilber (1980), Rogers (1981), Lundqvist (1987), Rogers & Samuels (1987), Samuels & Rogers (1987), and Vasilyeva (1988, 1997). A key to the Camarops species in the Americas was provided by San Martin & Lavin (1997).

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.
