In our previous study we demonstrated that the fruit ripening retardant Daminozide or Alar causes change in life history traits, distortion of adult wing structure, DNA damage in brain cells and mutagenic effects in fruit fly Drosophila melanogaster. As a continuation of the previous study the present work is designed to explore the metabolic modification of Daminozide following ingestion, the effects of Daminozide on the expression of genes which are pivotal for wing development and molecular interactions of Daminozide with those proteins involved in wing patterning. We demonstrated through reporter gene construct assay using X-gal staining method and transgenic Drosophila melanogaster stocks that the vestigial, wingless and decapentaplegic genes in wing imaginal disc from 3rd instar larvae exhibited reduced expression when exposed to Daminozide in compare to control larvae. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) of those genes confirmed that exposure to Daminozide reduces the transcription level of those genes. In silico approach with molecular docking study revealed Daminozide may bind and interfere with the optimal functioning of expressed wing signaling proteins. © 2019 Elsevier B.V.
