Abstract

Circadian clock enables organism's to adapt under fluctuating environmental conditions by coupling of behavioral, physiological and molecular processes in a wide variety of organisms including bacteria, fungi, plants, birds and mammals. The endogenous circadian system functions to organize behavior and physiology to adapt to and anticipate environment changes in light and temperature. The present study is an attempt to understand enzyme profiles (alpha- and beta-esterases) of Drosophila agumbensis and Drosophila nagarholensis under light/dark (LD), constant dark (DD) constant light (LL), conditions over twenty generations. A polyacrylamide gel electrophoresis (7.5% - Native gel) was used to study the esterase expression patterns in two species of the montium subgroup of Drosophila. Alpha- and beta-esterase expression was significantly decreased in LL when compared to LD and DD at both the generations and species. In all the light regimes, females were found to have significantly higher level of alpha- and beta-esterase expression than males. Flies were maintained under different light regimes showed difference in their expression patterns with respect to alpha- and beta-esterases. The present study showed that constant light conditions affect the expression of esterases in D. agumbensis and D. nagarholensis.
