6.45kb XhoI-ApaI fragment of osk genomic DNA including 2.3kb of upstream and 1.1kb of downstream sequences.
osk1/Df(3R)p-XT103 embryos carrying four copies of P{osk+6.45} are wild type.
Four copies of the construct P{osk+6.45} causes the formation of 40-60 pole cells. Embryos carrying four copies of osk are frequently abnormal with defects in the head, thorax and abdominal and telson structures.
osk+t6.45 rescues oskA87/Df(3R)p-XT103
osk+t6.45 rescues osk187/Df(3R)p-XT103
osk+t6.45 rescues osk1/Df(3R)p-XT103
Rescues the abdominal and germ line defects of embryos derived from osk1/Df(3R)p-XT103 females.
