Abstract

Biological systems are elegant timekeepers that control cycles of varied periodicity. These cycles include timekeepers to regulate period length and executors to enact the rhythmic behavior. Roundworm digestion is a periodic motor program in which three sequential muscle contractions, occurring every ~50 seconds, lead to waste release. I have discovered that the calcineurin gene, tax-6, appears to affect cycle timing. Mutation of tax-6 causes shortened digestion cycles. I will share my data demonstrating tax-6’s role in biological timekeeping.
