摘要

New Agricultural Research Service (ARS)-led discoveries about a gene that makes tomatoes ripen may lead to tastier tomatoes, according to an article in the recent issue of Science magazine. ARS researchers in Ithaca, N.Y., along with scientists fromthe Boyce Thompson Institute for Plant Research at Cornell University, Texas A&M University, and Jcallots Hill Research Station in the United Kingdom have developed new scientific information about the ripening-inhibitor (RIN) gene that controls ripening in tomatoes. Previously, researchers knew that ethylene, a gas naturally produced by plants, stimulates ripening in many fruits, including the tomato. According to ARS molecular biologist Jim Giovannoni, an additional genetic trait in tomatoes -- and probably other fruits -- also affects ripening and various quality characteristics. Work by Giovannoni and his team reveals that the RIN gene is a regulatory gene, a special kind of gene that controls the activity of other genes. The RIN gene affects bothethylene production during ripening and other processes of ripening that are not dependent upon ethylene.
