Senescence in a Bacterium with Asymmetric Division

Martin Ackermann, Stephen C. Stearns, and Urs Jenal

Abstract: Science 300, 1920 (2003).

Senescence is a deterioration of function with age manifested as a decrease in reproduction and survival. Prokaryotes are considered to be nonsenescent and potentially immortal organisms. In this Brevia, Ackermann et al. show that an asymmetrically dividing bacterium, Caulobacter crescentus, exhibits a decrease in reproductive output with age. This organism may be used as a model system for studies of the fundamental properties of senescence.
