3.5kb HpnI-HindIII genomic fragment containing Dvir\Pdf (includes 1.9kb of sequence upstream of the coding region and 0.9kb of sequence downstream of the coding region).
D. melanogaster flies carrying Dvir\Pdf+t3.5 in an otherwise wild-type background have normal locomotor activity rhythms under constant darkness conditions.
Dvir\Pdf+t3.5 is a suppressor of abnormal locomotor rhythm phenotype of Pdf01
The defects in locomotor activity rhythms seen in D. melanogaster Pdf01 flies under constant darkness conditions are completely rescued if the flies are also carrying Dvir\Pdf+t3.5.
