Description
Heejung Cho and co-authors studied how onions defend themselves with a pungent chemical in two thousand twenty-four. Onions make isoallicin, the compound behind their sharp bite, when cells are damaged. An enzyme kept in a cell sac is released and starts the reaction.
The team mapped the genes for that enzyme and for a related tear-causing factor in the onion genome. Many enzyme copies lack the signal that sends them to the sac, so they stay in the cell fluid. Tests showed these copies make isoallicin even in intact tissue. The authors describe a dual defense: a steady guard in whole tissue, plus a surge when tissue is bitten.
