    Abstract:
    Concentrations of ATP, ADP, AMP, cAMP as well as pyruvate and glucose-6-phosphate were measured in B. lastocladiella emersonii cells developing via RS morphogenetic pathway. They varied significantly in the course of development (1.3-14.8 mumole/g dry weight for the sum of ATP+ADP+AMP; 0.012-5.3 nmole for cAMP; 0.47-1.9 mumole for pyruvate; 0.36-4.78 mumole for glucose-6-phosphate). At the same time the adenylate energy charge remained essentially unchanged (about 0.8) from the middle of exponential growth till the end of the stationary phase. At the late stages of RS-sporangia formation the concentration of all the above compounds decreased by about 10 times, and the adenylate energy charge only by 30%. Positive correlation between the levels of ATP and cAMP in RS cells was demonstrated. The concentration of adenylic nucleotides and cAMP showed the most noticable changes at the end of exponential growth; transition of the point of no return was not accompanied by significant changes in the pools of adenylic system, cAMP or energy charge.
