Abstract excerpt
The longevity of plant leaf organs is genetically determined. However, the molecular mechanisms underlying the control of longevity are still largely unknown. Here, we describe a T-DNA-insertional mutation of Arabidopsis thaliana that confers extended leaf longevity. The mutation, termed ore4-1, delays a broad spectrum of age-dependent leaf senescence, but has little effect on leaf senescence artificially induced...
