The Expression of UGT46A1 Gene and Its Effect on Silkworm Feeding

The silkworm, Bombyx mori, uses a complex olfactory system to determine whether the food is edible. As an odor degrading enzyme, UDP-glycosyltransferase (UGT) participates in degradation of molecules silkworm. By sequencing whole genome silkworm NB and using comparative genomics methods, we found that UGT46A1 unique species eat mulberry leaves. Bioinformatics shows its function may be related feeding habits In this study, it was through quantitative real-time polymerase chain reaction (qRT-PCR) highly expressed heads silkworms, which consistent with conjecture involved recognition. RNA interference (RNAi) used knock down expression UGT46A1. observing silkworm’s tendency toward leaves selectivity, silkworms successfully knocked gene altered their ability find weakened, but they could more plants other than This evidence indicates affect by influencing
