In our project we made a device with these three pheromones and expressed them by transient expression it in our plant chasis, ''Nicotiana benthamiana''. In order to check if the insect sexual pheromones were present, we performed the analysis using HS-SPME coupled to GC-MS. We observed to additional peaks in the transformed plants that were not present in the control and have a similar mass spectrum and retention time as the standards, which confirmed that both molecules were the desired pheromones, (Z)-11-hexadecen-1-ol and (Z)-11-hexadecenyl acetate.

HarFAR

HarFAR-3 fatty acid reductase from Helicoverpa armigera with an ER retention signal (KKYR) attached to the C-terminal end. Codon optimization was perfomed for Nicotiana benthamiana.

Usage and Biology

The HarFAR protein is a fatty acid reductase coming from Helicoverpa armigera which transforms fatty acids into fatty alcohols.

Part:BBa_K1554001 (AtrΔ11), Part:BBa_K1554002 (HarFAR) and Part:BBa_K1554003 (EaDAcT) are enzymes of a biosynthesis pathway that lead to the production of insect sexual pheromones, Z11-16:OH and Z11-16:OAc, using palmitate as substrate.

In our project we made a device with these three pheromones and expressed them by transient expression it in our plant chasis, Nicotiana benthamiana. In order to check if the insect sexual pheromones were present, we performed the analysis using HS-SPME coupled to GC-MS. We observed two additional peaks in the transformed plants that were not present in the control and had a similar mass spectrum and retention time as the standards, which confirmed that both molecules were the desired pheromones, (Z)-11-hexadecen-1-ol and (Z)-11-hexadecenyl acetate.
