(i) The pCasper-Gateway(W)-LexA::GAD vector was created by excision of the Repo promotor fragment with NotI and AccI (Roche) from pCasper-Repo-LexA::GAD.8 (link) Blunt ends were created with the Klenow fragment of DNA Polymerase III (Promega), then the Gateway Reading Frame B (Invitrogen) was ligated into the vector using T4 DNA Ligase (Promega). The plasmid was transformed into DB3.1 cells (Invitrogen) and selected for Kanamycin resistance. DNA was extracted and verified by sequencing. The sequence of the vector is available as a supplementary data file (Suppl. 1 ).
(ii) The pLOT-Gateway vector was created by opening the pLexOp-vector8 (link) with EcoRI (Roche). Ends were blunted, the Gateway Reading Frame B (Invitrogen) was ligated in and the vector was introduced into DB3.1 cells as outlined above. The sequence of the vector is available as a supplementary data file (Suppl. 2 ).
(iii) Sensory LexA::GAD driver line: A 3.3 kb fragment from the Cha promotor was amplified by Polymerase Chain Reaction (PCR) using the following Gateway primers: attB1-GAA TTC TTA ATT GAA AAT AAA CAT TAA GG and attB2-GGA TCC GGT TGG TTT GGC CCC TTT TTC TTT GTC GCT. The PCR product was introduced into pDONRTM221 (Invitrogen) via Gateway cloning to create the pEntry-vector. In the subsequent Gateway cloning reaction this vector was combined with the newly developed pCasper-Gateway-LexA::GAD (above) to recombine the Cha promotor fragment with the LexA::GAD. DNA was purified using a Qiagen Midi Kit and transgenic lines were generated by BestGene Inc., (Chino Hills, CA, USA).
(iv) lexAop-myr-mCherry was created using the Multisite Gateway technique. One pEntry vector for the myristoylation site was created using the primers: attB1-ATG GGC AAC AAA TGC TCC AG and attB5r-TGG TCT GAT GAT GTC AAC CCC. Another, pEntry-mCherry entry vector was generated using the primers attB5-AAGAGCTCCGCCACCATGG and attB2-GGT TTA CGT CAC GTG GAC CGG TG. Both pEntry-vectors were combined into the new pLOT-Gateway vector using the MultiSite Gateway Kit from Invitrogen. Clones were selected on Ampicillin plates and DNA isolated and sequenced. Purified DNA was sent for embryo injection services to BestGene Inc., (Chino Hills, CA, USA).
