Isolated genes which are expressed during plant senescence are provided. Inparticular, a gene is provided which encodes a receptor-like protein kinasewhich is preferentially expressed in plant leaves early in the process ofplant senescence. Additionally, a gene encoding S-adenosyl methionine synthasewhich is expressed during the process of plant senescence is provided.Promoters from genes expressed during plant senescence are provided andoperably linked to a foreign gene to provide developmental-specific expressionof the foreign gene in a transformed plant.
