Rice-blast Fungus
Rice blast is caused by a fungus known as Magnaporthe oryzae (formerly Magnaporthe grisea). It produces sexual spores in structures called asci and is a member of the fungus group ascomycetes. It is part of the newly erected family Magnaportheceae. The asci can be found in specialized structures known as perithecia. The mycelium of M. oryzae is septate and the nuclei within the mycelium and spores of this fungus are haploid (TeBeest, Guerber, & Ditmore,…show more content… The suit has a closed hood to prevent inhaling the powder. Said pharmaceutical chemist Lloyd Matheson of the University of Iowa, who once inhaled some capsaicin accidentally: "It’s not toxic, but you wish you were dead if you inhale it." "One milligram of pure capsaicin placed on your hand would feel like a red-hot poker and would surely blister the skin," said capsaicin expert Marlin Bensinger.
Capsaicin has evolved to protect chili peppers from mammalian predators. That's the theory of Dr. Michael Nee of the New York Botanical Garden. It has long been theorized that plants produces metabolites, which are chemicals not necessary for the primary survival of plants. These metabolites ward of animal predators, and possibly, competing plants.
Currently, capsaicin is registered for use as an animal repellent against attacking dogs, birds, voles, deer, rabbits and tree squirrels, and for use as an insect toxicant and repellent. Studies at Cedars-Sinai Medical Center preliminarily suggest that capsaicin is beneficial to health and might help fight prostate cancer (Bird, 2014).
Aside from its medicinal properties, capsaicin and several related compounds are called capsaicinoids and are produced as a secondary metabolite by chili, probably as deterrents against certain fungi (Ahiladevi & Prakasm,
