Tissue-specific disruption of rhythmic expression of Dec1 and Dec2 in clock mutant mice.

abstract：:Female Drosophila melanogaster, like many other organisms, exhibit different behavioral repertoires after mating with a male. These postmating responses (PMRs) include increased egg production and laying, increased rejection behavior (avoiding further male advances), decreased longevity, altered gustation and decrease...
