Identification and Characterization of In-planta Expressed Secreted Effector Proteins from Magnaporthe oryzae
Rice blast disease, caused by the fungus Magnaporthe oryzae, is one of the most serious diseases of rice. Interactions between rice and M. oryzae involve the recognition of cellular components and the exchange of complex molecular signals from both partners. How these interactions occur in rice is …

Limits of detection of Magnaporthe oryzae Triticum pathotype in wheat seed: implications for pathogen dissemination
… wheat, caused by the seed-borne fungal pathogen Magnaporthe oryzae Triticum pathotype (MoT). The first objective of this research was to establish the detection threshold for MoT in infected wheat seeds as a function of sensitivity and specificity of a modified quantitative and conventional PCR …

Magnaporthe Oryzae Telomeric Retrotransposon (moter) Relics Further Highlight Telomere Dynamics In A Rapidly Evolving Fungal Pathogen
<p>The telomeres of M. oryzae can experience unique rearrangements within a single generation. These rearrangements are frequently attributed to the presence of two retrotransposons (MoTeR 1 and MoTeR 2) that are endemic to the telomeres. These rearrangements can leave footprints within the …

Protein Kinase A Regulates Hyphal Growth by Relieving the Interaction of MoSfl1 with the Cyc8-Tup1 Co-repressor in Magnaporthe oryzae
… plant pathogenic fungi. In the rice blast fungus Magnaporthe oryzae, it regulates surface recognition, appressorium turgor generation, and invasive growth. Two genes in M. oryzae named CPKA and CPK2 encode the catalytic subunits of cAMP-dependent protein kinase A. Previous studies have shown that …

Rice Blast Disease in the U.S. and Africa: Determination of Pathogen Diversity and the Identification of Resistance Genes for Disease Management
<p>Rice blast caused by Magnaporthe oryzae (= Pyricularia oryzae) B. Couch, is a leading disease of rice. Magnaporthe oryzae exhibits a high degree of diversity. The diversity of isolates of M. oryzae from Africa and the U.S. were examined using vegetative compatibility and virulence phenotyping as …

THE ROLE OF PKS1 MEDIATED SECONDARY METABOLISM IN HOST PENETRATION AND COLONIZATION DURING RICE BLAST DISEASE
MAGNAPORTHE ORYZAE CAUSES DEVASTATING RICE BLAST DISEASES ALL OVER THE WORLD. THIS FUNGUS DIFFERENTIATES A SPECIALIZED INFECTION STRUCTURE, THE APPRESSORIUM, TO PENETRATE THE RICE LEAVES DURING INITIATION OF THE DISEASE. A LAYER OF CONDENSED MELANIN IS FORMED IN THE APPRESSORIUM TO MAINTAIN A HIGH …

Molecular and cellular analyses of pathogenicity and host specificity in rice blast disease
… blast disease caused by the ascomycetous fungus Magnaporthe oryzae. Rice blast has become a model system for the study of fungal plant diseases based on its global relevance to agriculture and on our ability to apply molecular genetic and genomic analyses to both the pathogen and the plant. We …

Exploring Genome Structure and Gene Regulation Related to Virulence in Fungal Phytopathogens Using Next Generation Sequencing Techniques
… event. In Chapter 4, seven field isolates of Magnaporthe oryzae were sequenced and their genome content compared. Over 10,000 SNP and Indel locations were identified as well as genes under strong positive selection, which are considered potential virulence related genes. While in a RNA-Seq …

IDENTIFICATION OF COMMON MECHANISMS TO INTRACELLULARLY ACCOMMODATE BENEFICIAL OR PATHOGENIC FUNGI IN RICE
… nutrient uptake from the soil. In contrast, Magnaporthe oryzae causes rice blast disease, which significantly reduces annual rice yields. Despite their opposing roles, their respective colonization of rice roots share similarities at the transcriptional and morphological level in host cells. …

Common Accommodation Mechanisms for Mutualistic and Detrimental Fungi in Oryza sativa (Rice) Roots
… resisting invasion of the detrimental fungus M. oryzae, a major causative agent of the rice blast (leaf) disease. M. oryzae can also invade rice roots with simple non-melanised hyphopodia formed on the rice root surface, very similar to R. irregularis. This similarity in behaviour has raised …
