Title: Increasing leaf longevity and disease resistance by altering salicylic acid catabolism

Abstract

The present invention relates to a transgenic plant having an altered level of salicylic acid 3-hydroxylase ("S3H") protein, compared to that of a non-transgenic plant, where the transgenic plant displays an altered leaf senescence phenotype, relative to a non-transgenic plant. The present invention relates to a mutant plant comprising an inactivated gene encoding S3H protein, where the mutant plant displays a premature or precocious leaf senescence phenotype, relative to a non-mutant plant. The present invention also relates to methods for promoting premature or precocious leaf senescence in a plant, delaying leaf senescence in a plant, and making a mutant plant having a decreased level of S3H protein compared to that of a non-mutant plant, where the mutant plant displays a premature or precocious leaf senescence phenotype relative to a non-mutant plant. The present invention also relates to inducing or promoting pathogen resistance in plants.
