Parasexual 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 کاملPlants as alternative hosts for Salmonella.
Recent findings show that many human pathogenic bacteria can use multiple host organisms. For example, Salmonella Typhimurium can use plants as alternative hosts to humans and other animals. These bacteria are able to adhere to plant surfaces and actively infect the interior of plants. Similarly to the infection of animal cells, S. Typhimurium suppresses plant defense responses by a type III se...
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) ...
متن کاملEnhanced disease resistance and drought tolerance in transgenic rice plants overexpressing protein elicitors from Magnaporthe oryzae
Exogenous application of the protein elicitors MoHrip1 and MoHrip2, which were isolated from the pathogenic fungus Magnaporthe oryzae (M. oryzae), was previously shown to induce a hypersensitive response in tobacco and to enhance resistance to rice blast. In this work, we successfully transformed rice with the mohrip1 and mohrip2 genes separately. The MoHrip1 and MoHrip2 transgenic rice plants ...
متن کاملFungal Virulence and Development Is Regulated by Alternative Pre-mRNA 3â•2End Processing in Magnaporthe oryzae
RNA-binding proteins play a central role in post-transcriptional mechanisms that control gene expression. Identification of novel RNA-binding proteins in fungi is essential to unravel post-transcriptional networks and cellular processes that confer identity to the fungal kingdom. Here, we carried out the functional characterisation of the filamentous fungus-specific RNAbinding protein RBP35 req...
