Scientists identify thousands of plant genes activated by ethylene gas



Discovery by Salk-lead team could lead to better ways to control growth and ripening of agricultural plants

It's common wisdom that one rotten apple in a barrel spoils all the other apples, and that an apple ripens a green banana if they are put together in a paper bag. Ways to ripen, or spoil, fruit have been known for thousands of years-as the Bible can attest-but now the genes underlying these phenomena of nature have been revealed.

In the online journal eLIFE, a large international group of scientists, led by investigators at the Salk Institute for Biological Studies, have traced the thousands of genes in a plant that are activated once ethylene, a gas that acts as a plant growth hormone, is released.
