2.7. Generation of the ACS-4::GFP strain
The strain BX265 expresses the translational fusion waEx18
(acs-4p::ACS-4::GFP). The strain was constructed using PCR to amplify
the acs-4 genomic and promoter region (approximately 3 kb upstream
of the ATG start site) and cloned into the pPD95.79 vector in frame to
create a C terminal GFP fusion protein. The plasmid construct was
microinjected into N2 worms and GFP positive worms were selected
