Novel gene encoding an f-box protein which regulates leaf longevity in arabidopsis thaliana and mutant gene thereof

摘要

The present invention relates to an ORE9 gene that regulates leaft longevity in Arabidopsis thaliana, an ore9 mutant gene that delays the leaf longevity by repressing the physiological and biochemical changes involved in leaf senescence, and the use of the genes. The ORE9 gene regulating leaf longevity and the ore9 mutant gene thereof according to the present invention can be used for practical purposes such as improvement of plant productivity and pre- and post-harvest storage and development of the bioprobe for investigating the leaf longevity-associated gene and repressor of leaf longevity in plants.
