Genetic Control of Aging in the Ascomycete Podospora anserina

Abstract

Podospora anserina is a filamentous fungus which shows after prolonged vegetative growth different symptoms of aging: The growth rate of a colony (mycelium) decreases, the pigmentation of the culture changes, the peripheral hyphae (filamentous “cells” of a mycelium) become slender and undulate, and the formation of aerial hyphae is drastical reduced. Some days after the first occurrence of these morphological symptoms of aging, the culture stops growing and dies. Since the first description of this “senescence syndrome” in the early 1950s [37], senescence has been extensively investigated at the physiological, genetic, and molecular levels. Emerging from these investigations are first ideas about the molecular mechanisms controlling aging in this simple eukaryotic microorganism.
