Abstract:
:The sphere-rod-sphere morphology cycle of Arthrobacter crystallopoietes was accompanied by changes in the rate of growth and the rates of DNA, RNA and protein synthesis. The patterns of macromolecule synthesis resembled those found in other bacteria during a step-up followed by a step-down in growth rate. During the step-up in growth spherical cells grew into rods and macromolecules were synthesized in the absence of cell division. During step-down, successive rounds of septation produced progressively smaller cells which did not separate and remained in chains. The morphology of the cells was dependent on the growth rate and could be altered by changing the dilution rate in the malate-limited chemostat. Gradual transitions in morphology and gradual increases in macromolecule content of the cells occurred as the growth rate was increased in the chemostat. Sphere to rod morphogenesis occurred when DNA synthesis was inhibited by treatment with mitomycin C or by thymine starvation. The DNA-deficient rods did not divide and eventually lysed. DNA, RNA and protein synthesis were continuously required for the reductive division of rods to spheres.
