AG-BIO: Leaf Life Is Extended - Brief Article

Applied Genetics News, March, 2000

Senesco Technologies, Inc. (34 Chambers St., Princeton, NJ 08542; Tel: 609/252- 0680, Fax: 609/252-0049; Email: info@senesco.com, Website: www.senesco.com) has been able to significantly delay natural leaf senescence in Arabidopsis thaliana plants by reducing the expression of the deoxyhypusine synthase (DHS) gene. This delayed senescence is accompanied by substantially larger leaf size. Delayed senescence may increase crop yield because plants are able to invest more energy and resources to the production of seed.

"Senesco's proof of concept indicates that silencing the DHS gene has broad- based application because our results indicate that this gene is involved in the initiation of senescence in all plant tissues," comments Ruedi Stalder, chairman and CEO of Senesco.
