Fluctuation of protein level in Haemolymph, ovary and Hepatopancreas during non-reproductive and reproductive Molt Cycle of Albunea symmista
Journal Title: Journal of Research in Biology - Year 2011, Vol 1, Issue 2
Abstract
In Albunea symmista, an antagonistic relationship could be visualized between molting and reproduction. Proteins necessary for the formation and hardening of the exoskeleton and maturation of ovary .The biochemical link between molting and reproductive cycle of Albunea symmista was established through the estimation of protein in haemolymph, ovary and hepatopancreas. The haemolymph protein level during non- reproductive molt cycle gradually raised from post molt to early premolt (2.7± 0.2 to 6.3 ± 0.2 mg/ml)and it get decreased in the late premolt due to water influx through new cuticle (6.3 ±0.2 to 4.3 ± 0.1 mg/ml).However during reproductive molt cycle , the protein content of haemolymph also gets decreased due to reproductive activities (3.9 ± 0.2 to 2.1 ±0.1 mg/ml).The ovarian protein level during non-reproductive molt cycle get gradually increased due to accumulation of protein (74.8 ± 1.5 to 145.8 ± 1.7 μg/mg)During reproductive molt cycle fluctuation of protein level occurs soon after spawning , where the ovary remains in the spent condition (47 μg/mg) then after hatching, the ovary continues its maturation (47 to 74.9 ± 3.7 μg/mg).The protein content in the hepatopancreas shows fluctuation both during reproductive molt cycle (29.5 ± 1.9 to 148.2 ± 1.8 μg/mg) and non-reproductive molt cycle (144.8±1.0 to 125.1 ±5.2 μg/mg).
