Autoradiographic study of hyphal growth during aerial mycelium development in Streptomyces antibioticus.
نویسندگان
چکیده
The pattern of growth of aerial mycelium in Streptomyces species was investigated by autoradiography. Colonies of Streptomyces antibiotics were labeled with N-acetyl-D-[1-3H] glucosamine to localize the sites of hyphal growth during the development of aerial mycelium. Autoradiographs obtained with sections of the colonies revealed that hyphal growth occurs not only at the top of the colony but also in the inner zones of the aerial mycelium.

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...

Development-associated cell-death processes were investigated in detail during the growth and differentiation of Streptomyces antibioticus ATCC 11891 on confluent surface cultures, by using fluorescent viability probes, membrane and activity fluorescence indicators, and electron microscopy analysis. A previously unsuspected complexity was revealed, namely the presence of a very young compartmen...

Two exocellular nucleases with molecular masses of 18 and 34 kDa, which are nutritionally regulated and reach their maximum activity during aerial mycelium formation and sporulation, have been detected in Streptomyces antibioticus. Their function appears to be DNA degradation in the substrate mycelium, and in agreement with this proposed role the two nucleases cooperate efficiently with a perip...
متن کاملTime-lapse microscopy of Streptomyces coelicolor growth and sporulation.
Bacteria from the genus Streptomyces are among the most complex of all prokaryotes; not only do they grow as a complex mycelium, they also differentiate to form aerial hyphae before developing further to form spore chains. This developmental heterogeneity of streptomycete microcolonies makes studying the dynamic processes that contribute to growth and development a challenging procedure. As a r...
متن کاملSMC protein-dependent chromosome condensation during aerial hyphal development in Streptomyces.
Members of the SMC (structural maintenance of chromosomes) protein family play a central role in higher-order chromosome dynamics from bacteria to humans. So far, studies of bacterial SMC proteins have focused only on unicellular rod-shaped organisms that divide by binary fission. The conversion of multigenomic aerial hyphae of the mycelial organism Streptomyces coelicolor into chains of unigen...
