| Research Abstract |
Timing of reproduction including flowering, spawning, or mating of many organisms has restricted time-zone during a successive organism action, for example, particular seconds, hours, days, seasons or years. We cloned the clock gene period from two strains of melon fly, in one individuals mate early in the day, whilst in the other individuals mate later. The deduced amino acid sequences of PERIOD proteins for these two strains were reported to be identical. We cloned another clock gene cryptochrome (cry) from the two strains, and found two stable amino acid substitutions in the strains. The results suggest the influence on allochronic reproductive isolation of clock gene.
