Blast, Pyricularia grisea (Cooke) Sacc., is one of the most destructive diseases of rice worldwide and canresult in significant reductions in yield. The use of resistant cultivars is the most economical and effectiveway of controlling rice blast. A variety of DNA markers, including plant defense-related candidategene markers are available for genetic characterization and molec...
the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
Metabolomic approaches were used to elucidate some key metabolite changes occurring during interactions of Magnaporthe grisea--the cause of rice blast disease--with an alternate host, Brachypodium distachyon. Fourier-transform infrared (FT-IR) spectroscopy provided a high-throughput metabolic fingerprint of M. grisea interacting with the B. distachyon accessions ABR1 (susceptible) and ABR5 (res...
Aeluropus littoralis belong to poaceae family. It often grows in salty soils. In this study reaction of A. littoralis to rice pathogens (Pyricularia grisea, Rhizoctonia solani and Bipolaris oryzae) was investigated at greenhouse and field conditions under artificial inoculation. These three mentioned fungi were isolated from rice plants and then propagated and separately inoculated on Aeluropus...
Cyclophilins are peptidyl prolyl cis-trans isomerases that are highly conserved throughout eukaryotes and that are best known for being the cellular target of the immunosuppressive drug cyclosporin A (CsA). The activity of CsA is caused by the drug forming a complex with cyclophilin A and inhibiting the calmodulin-dependent phosphoprotein phosphatase calcineurin. We have investigated the role o...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
The causal agent of rice blast disease, the ascomycete fungus Magnaporthe grisea, infects rice (Oryza sativa) plants by means of specialized infection structures called appressoria, which are formed on the leaf surface and mechanically rupture the cuticle. We have identified a gene, Magnaporthe metallothionein 1 (MMT1), which is highly expressed throughout growth and development by M. grisea an...
this thesis attempts to measure learning styles, self efficacy and intrinsic motivation as predictors of iranian ielts reading comprehension. in order to address this issue, a quantitative study was conducted on some randomly selected intact students at ferdowsi university. these two groups were assigned as they were undergraduate (ba=91) and graduate (ma =74) students; they were all aged betwe...
Finger millet is the third important cereal crop in Sri Lanka, mostly cultivated rainfed uplands dry and intermediate zones. Blast disease (leaf, finger, neck blast) caused by Magnaporthe grisea economically devastating to rice finger worldwide. Host resistance most viable option for managing as it mainly grown low-input systems. One hundred thirty-nine accessions collected from Plant Genetic R...
We isolated and identified four rice genes, OsBIERF1 to OsBIERF4 (Oryza sativa benzothiadiazole (BTH)-induced ethylene responsive transcriptional factors (ERF)) and analyzed their expressions in rice disease resistance response and under various abiotic stress conditions. The OsBIERF1-4 proteins contain conserved ERF domains, but are categorized into different classes of the previously characte...
