Effects of NOS mutation, NOS knockdown, and macNOS overexpression on free-running locomotor rhythms.

The left-most column explains the types of experiments and where the drivers are expressed. n, number of flies. %R, % of rhythmic flies. CTR, control. Oxp, over-expression. KD, knockdown. OP, optic lobes. Mean periods and rhythmicity of the test groups were compared with those of control groups using Student’s t-test and chi-square test, respectively. Mutants were compared with Canton-S and flies for knockdown and overexpression were compared with GAL4-only controls.
