Description 87-91
The temporal expression patterns of timeless
(tim) in Drosophila melanogaster at various time points were studied
in intestine and salivary gland of wild type (WT), vestigial (vg) and cryptochrome-absent
(cryb) mutants under 12 hr:12 hr

white light:darkness (LD) and 12 hr:12 hr blue
light (450 nm):darkness (BD) conditions. At ZT 06 and ZT 10, tim expression
was almost nil and at ZT 18 and ZT 22, the expression was most pronounced in WT
and mutants, when compared to other time points. As vg flies have
greatly reduced wings, their gross locomotor activity was poorer and levels of tim
expression were also least than WT flies. The weaker expression of tim in
cryb flies suggested the significant role of blue light
photoreceptor cryptochrome for a stronger synchronization of circadian
clock. The expression patterns of rim in the salivary gland of larvae
further suggested the presence of peripheral oscillators during the
developmental stages.
