【Objective】This study aims to clone Carpomya vesuviana Costa odorant binding protein( Cvco OBP) and analyze expression profile of Cvco OBP in order to lay the foundation of researching Cvco OBP in Carpomya vesuviana Costa.【Method】Based on transcriptome sequencing of cephalic RNA,the study has analyzed Cvco OBP according to alignment and phylogenetic analysis. The research was also conducted into the tissue specific expression of Cvco OBP by semi- quantitative reverse transcription and polymerase chain react...
