بیماری بلاست (blast) با عامل magnaporthe oryzae مهم‏ترین بیماری برنج در جهان می‏باشد. استفاده از سموم شیمیایی اگر چه باعث کنترل بیماری می‏گردند، اما آسیب‏های جدی متوجه انسان و محیط زیست می‏کنند. امروزه کنترل بیولوژیک بیماری‏های گیاهی به عنوان یک روش جایگزین و بی‏خطر، مورد توجه و تأکید ویژه‏ای قرار گرفته است. در این تحقیق، نمونه برداری از خاک شالیزار و اندام‏های هوایی برنج در مناطق مختلف استان م...

Magnaporthaceae is a family of ascomycetes that includes three fungi of great economic importance: Magnaporthe oryzae, Gaeumannomyces graminis var. tritici, and Magnaporthe poae. These three fungi cause widespread disease and loss in cereal and grass crops, including rice blast disease (M. oryzae), take-all disease in wheat and other grasses (G. graminis), and summer patch disease in turf grass...

Species of Pyricularia (magnaporthe-like sexual morphs) are responsible for major diseases on grasses. Pyricularia oryzae (sexual morph Magnaporthe oryzae) is responsible for the major disease of rice called rice blast disease, and foliar diseases of wheat and millet, while Pyricularia grisea (sexual morph Magnaporthe grisea) is responsible for foliar diseases of Digitaria. Magnaporthe salvinii...

Deciphering the genetic bases of pathogen adaptation to its host is a key question in ecology and evolution. To understand how the fungus Magnaporthe oryzae adapts to different plants, we sequenced eight M. oryzae isolates differing in host specificity (rice, foxtail millet, wheat, and goosegrass), and one Magnaporthe grisea isolate specific of crabgrass. Analysis of Magnaporthe genomes reveale...

A series of diaryl amines, ethers and thioethers were synthesized under microwave irradiation efficiently at presence of KF/Al2O3 in 83%-96% yields without any solvent. The salient characters of this method lie in short reaction time, high yields, general applicability to substrates and simple workup procedure. At the same time, their antifungal biological activities against six phytopathogen w...

abstract sclerogenic fungal pathogens, are among the most important diseases of rice plant. sheath blight caused by rhizoctonia solani is one of the economically important diseases that attack a wide range of hosts. stem rot (magnaporthe salvinii) has also been found with different severity in most fields of guilan province. to determine sclerogenic fungal pathogens of rice plant, 141 isolates ...

World wheat production is now under threat due to the wheat blast outbreak in Bangladesh in early March 2016. This is a new disease in this area, indicating the higher possibility of this pathogen spreading throughout the Asia, the world's largest wheat producing area. Occurrence of this disease caused ~3.5% reduction of the total wheat fields in Bangladesh. Its economic effect on the Banglades...

Rice blast, caused by the fungal pathogen Magnaporthe oryzae, is the most destructive disease of rice and causes tremendous losses of rice yield worldwide. To explore the molecular mechanisms involved in the rice-M. oryzae interaction, we conducted a time-course phosphoproteomic analysis of leaf samples from resistant and susceptible rice cultivars infected with M. oryzae. This data article con...

The whole-genome assembly of a unique rice isolate from India, Magnaporthe oryzae RMg-Dl that causes blast disease in diverse cereal crops is presented. Analysis of the 34.82 Mb genome sequence will aid in better understanding the genetic determinants of host range, host jump, survival, pathogenicity, and virulence factors of M. oryzae.

Plant innate immunity is mediated by pattern recognition receptors (PRRs) and intracellular NB-LRR (nucleotide-binding domain and leucine-rich repeat) proteins. Overexpression of the endoplasmic reticulum (ER) chaperone, luminal-binding protein 3 (BiP3) compromises resistance to Xanthomonas oryzae pv. oryzae (Xoo) mediated by the rice PRR XA21 [12]. Here we show that BiP3 overexpression also co...
