Rice Blast

Rice blast, caused by the fungus Magnaporthe grisea, is a devastating disease affecting rice crops worldwide, characterized by the formation of an appressorium that generates high turgor pressure to penetrate the rice plant cuticle through autophagy and cellular differentiation. It poses a severe threat to global rice production, with recurrent epidemics occurring in major rice-growing regions including Kenya, Italy, and Bangladesh, where wheat blast was also recently observed. While developed countries manage the disease using resistant cultivars, optimized nitrogen use, and fungicides, control remains costly and challenging. In developing regions, particularly sub-Saharan Africa, where rice consumption is rising and locally adapted varieties like NERICA lack effective resistance, outbreaks can lead to total crop loss, causing economic devastation and food insecurity. The high cost of fungicides and limited availability of resistant varieties make controlling rice blast in these areas a critical agricultural challenge.

    Oligomycin B 11050-94-5
    Oligomycin B is an antibiotic that acts as a non-selective inhibitor of ATP Synthase. Oligomycin B increases mitochondrial membrane potential. Oligomycin B induces apoptosis and necrosis. Oligomycin B impairs the motility of Plasmopara viticola zoospores and induces their lysis. Oligomycin B inhibits Magnaporthe oryzae (wheat blast fungus) and suppresses the development of wheat blast. Oligomycin B reduces hyphal growth and spore germination of Botrytis cinerea, and protects Arabidopsis thaliana against Botrytis cinerea infection. Oligomycin B exacerbates cytotoxic brain edema in rats with cerebral cortical contusion, increases intracranial pressure and brain water content, and aggravates mitochondrial damage in these rats. Oligomycin B is used in studies related to grape downy mildew, traumatic brain injury, wheat blast, and gray mold.

    Tiadinil 223580-51-6 99.84%
    Tiadinil is a systemic acquired resistance (SAR) inducer, plant elicitor and antifungal agent. Tiadinil promotes the production of herbivore-induced plant volatiles in Camellia sinensis (tea plant). Tiadinil inhibits mycelial growth, spore germination and germ tube elongation of Stagonosporopsis citrulli in vitro. Tiadinil can be used in studies related to vine blight.
