Onions, in particular, produce a sulfur product that acts as a lacrimator, or a substance that causes tearing: “This volatile chemical escapes from the damaged onion into the air, and lands in ...
Stromatinia cepivora is a fungus in the division Ascomycota.It is the teleomorph of Sclerotium cepivorum, the cause of white rot in onions, garlic, and leeks. [2] The infective sclerotia remain viable in the soil for many years and are stimulated to germinate by the presence of a susceptible crop.
The chemical is released from onions, Allium cepa, as they are sliced. The release is due to the breaking open of the onion cells, which releases enzymes called alliinases . Alliinases then break down amino acid sulfoxides , generating sulfenic acids .

It is a destructive disease of fruits, vegetables, and ornamentals found worldwide, and affects genera from nearly all the plant families.

Too much moisture is what causes leafy greens to turn soft and rot. Here are four ways to keep moisture at a minimum: Here are four ways to keep moisture at a minimum: Buy only fresh greens.
As this ripening process occurs, working its way from the inside towards outer most tissue of the fruit, the observable changes of softening tissue, and changes in color and carotenoid content occur. Specifically, this process activates ethylene production and the expression of ethylene-response genes affiliated with the phenotypic changes seen ...
