Analysis of secreted proteins during conidial germination of Aspergillus oryzae RIB40.
To broaden our understanding of extracellular proteins of Aspergillus oryzae at the conidial germination stage, analyses of the secreted proteins during germination were carried out. Taka-amylase A (TAA), glucoamylase (GLAA), and aspergillopepsin A (PEPA) were identified as the main products by peptide mass fingerprinting. TAA and PEPA were detected simultaneously with the formation of germ tub...
متن کاملParasexual Recombination in Magnaporthe oryzae
Parasexual recombination is thought to be one of the causes of variation in the pathogenicity of rice blast fungus, Magnaporthe oryzae, which breaks down resistant rice varieties. In this study, the virulence and fitness of parasexual recombinants of M. oryzae were examined in vitro and in the field. According to the results of the genetic analysis of the pathogenicity of parasexual recombinant...
متن کاملR-SNARE Homolog MoSec22 Is Required for Conidiogenesis, Cell Wall Integrity, and Pathogenesis of Magnaporthe oryzae
Soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins mediate intracellular vesicle fusion, which is an essential cellular process of the eukaryotic cells. To investigate the role of SNARE proteins in the rice blast fungus Magnaporthe oryzae, MoSec22, an ortholog of Saccharomyces cerevisiae SNARE protein Sec22, was identified and the MoSEC22 gene disrupted. MoSe...
متن کاملGermination and infectivity of microconidia in the rice blast fungus Magnaporthe oryzae
The rice blast fungus Magnaporthe oryzae is a model for studying fungal-plant interactions. Although it produces two types of spores (microconidia and macroconidia), previous infection studies have exclusively dealt with macroconidia. Germination of microconidia has not been reported, and their role in plant infection is not defined. Here we show that approximately 10% of microconidia germinate...
متن کاملEffectors and Effector Delivery in Magnaporthe oryzae
Rice blast caused by Magnaporthe oryzae is one of the most destructive fungal diseases of rice and a model for studying fungalplant interactions. The fungus penetrates plant cells with appressoria and develops the narrow primary invasive hyphae (IH) and, subsequently, the bulbous secondary IH. As a hemibiotrophic pathogen, biotrophic IH are enclosed in the extra-invasive-hyphal membrane (EIHM) ...
