Jra expression is generally consistent over this time period, with a peak at 0h APF.

(Sekyrova et al., 2010)

Jra transcript is expressed in salivary glands from 18 hours prior to puparium formation to 12 hours APF. Expression peaks from the middle of the late larval ecdysone pulse though 2 hours APF.

(Lehmann et al., 2002)

Jra transcripts are detected at a relatively constant level throughout development on northern blots. In situ hybridization shows that they are expressed uniformly at a low level in all cell types.

(Perkins et al., 1990)

Jra transcripts are observed throughout development at relatively constant levels on northern blots. By in situ hybridization, they are found in embyros in all tissues.

(Zhang et al., 1990)

Jra protein is expressed in the same motor neurons that express the Scer\GAL4^futsch-C380 driver.

(Sanyal et al., 2003)

Jra protein expression is widespread during embryogenesis. One tissue showing elevated Jra expression is the amnioserosa. During and following germ band retraction, the cells of the dorsal epidermis show elevated levels of Jra protein. The highest levels are found in the cells at the leading dorsal edge of the epidermis which are involved in the process of dorsal closure. Expression remains high in these cells throughout the process of dorsal closure. Elevated expression is also observed along the cephalic furrow.

(Kockel et al., 1997)

Jra protein is expressed posterior to the morphogenetic furrow in all cells entering the ommatidial cluster including photoreceptor cells, cone cells and the mystery cell. Its expression is transient. It is expressed in the cells as they are newly recruited to the ommatidial cluster and for 3-4 columns posteriorly.
