Rice blast, caused by the fungus Pyricularia oryzae L., is considered one of main threats to world rice production. The development resistant cultivars best and sustainable control alternatives. Plant breeding efforts have been accelerated genetic mapping (linkage associative) marker assisted selection. On other hand, genomic editing techniques, such as meganucleases (MNs), Zinc-finger nuclease...

Rice blast disease, caused by the fungus Pyricularia oryzae, is one of diseases that reduce rice yields in Thailand. The fungus’s dispersal influences this disease outbreak. This study aims to develop a mathematical model for spore dispersion, namely non-local diffusion equation terms kernel, adding factor causes dispersion due rain splash and adjusting infection term based on weather condition...

An epidemic of rice (Oryza sativa) blast occurred on cultivars Epagri 108 and 109 in the municipalities of Lagoa da Confusão and Duerê in the State of Tocantins, during the rice-growing season 199899. DNA fingerprinting and virulence phenotype analysis were utilized to determine the diversity of Pyricularia grisea isolates collected from these cultivars in one epidemic year. Rep-PCR analysis of...

Introduction: Alpha-Momorcharin (α-MMC) is a member of the ribosome-inactivating protein (RIP) family that has been widely used as an antitumor, antiviral and antifungal agent. Methods: In this study, codons DNA encoding α-MMC were optimized for expression in E. coli cloned into pET-28a(+) vector. The was then expressed strain BL21 (DE3) purified by nickel affinity chromatography. Results: Unde...
