Abstract
Wild-type, band, and fluffy strains of
Neurospora crassa
exhibit circadian rhythms of ribonucleic acid and deoxyribonucleic acid content in the growth-front hyphae of cultures grown on a solid medium. There is also a rhythm of
3
H-uridine incorporation into the nucleic acids of the band strain. Maximum incorporation precedes the peaks of nucleic acid content which occur during conidiation. As cultures age, ribonucleic acid content decreases rapidly and deoxyribonucleic acid content decreases gradually in standing, shake, and bubble cultures. A reduction of ribonuclease activity with age is also noted in standing and shake cultures. The nucleic acid content, nuclease activity, and changes associated with age vary with the culture conditions.
