摘要： The ocular albinism type 1 gene, named OA1, is a coding pigment cell-specific G protein-coupled receptor exclusively localized in intracellular organelles. However, the function of OA1 in insects remains generally unknown. In the present study, we explore for the first time the function of LdOA1 in the Asian gypsy moth, Lymantria dispar. To identify the function of LdOA1 gene in the development and growth of the Asian gypsy moth, the LdOA1 gene in third instar larvae was knocked down by RNAi. Compared with the controls, the knockdown of LdOA1 increased larval mortality but did not significantly affect their utilization of nutrition. Moreover, LdOA1 was stably transformed into the third chromosome of Drosophila melanogaster. The LdOA1 gene in the transformed D. melanogaster modulated the expression of heat-shock protein (hsp) and increased the expression of hsp genes under deltamethrin stress, which indicates that LdOA1 is involved in the regulation of hsp gene expression. These results deepen our understanding of the molecular function of OA1 in insects. (C) 2015 Elsevier Inc. All rights reserved.
