| pubmed-article:10225953 | pubmed:abstractText | During the life cycle of the streptomycetes, large numbers of hyphae die; the surviving ones undergo cellular differentiation and appear as chains of spores in the mature colony. Here we report that the hyphae of Streptomyces antibioticus die through an orderly process of internal cell dismantling that permits the doomed hyphae to be eliminated with minimum disruption of the colony architecture. Morphological and biochemical approaches revealed progressive disorganization of the nucleoid substructure, followed by degradation of DNA and cytoplasmic constituents with transient maintenance of plasma membrane integrity. Then the hyphae collapsed and appeared empty of cellular contents but retained an apparently intact cell wall. In addition, hyphal death occurred at specific regions and times during colony development. Analysis of DNA degradation carried out by gel electrophoresis and studies on the presence of dying hyphae within the mycelium carried out by electron microscopy revealed two rounds of hyphal death: in the substrate mycelium during emergence of the aerial hyphae, and in the aerial mycelium during formation of the spores. This suggests that hyphal death in S. antibioticus is somehow included in the developmental program of the organism. | lld:pubmed |
