cGAL, a temperature-robust GAL4–UAS system for Caenorhabditis elegans
Abstract
The GAL4–UAS system is a powerful tool for manipulating gene expression, but its application in Caenorhabditis elegans has not been described. Here we systematically optimize the system's three main components to develop a temperature-optimized GAL4–UAS system (cGAL) that robustly controls gene expression in C. elegans from 15 to 25 °C. We demonstrate this system's utility in transcriptional reporter analysis, site-of-action experiments and exogenous transgene expression; and we provide a basic driver and effector toolkit.

Some strains were provided by the CGC, which is funded by the NIH Office of Research Infrastructure Programs (grant P40 OD010440). Some imaging was performed at the Caltech Biological Imaging Facility with the support of the Caltech Beckman Institute and the Arnold and Mabel Beckman Foundation. H.W. is supported by the Della Martin Fellowship. J.L. was supported by NIH grant T32GM007616. This work is supported by the Howard Hughes Medical Institute, with which P.W.S. is an investigator. Data availability: The source data used for the plots in the main and supplementary figures are included in the supplementary materials. Other data are also available from the corresponding author upon request. The coding sequence of Gal4p from Saccharomyces kudriavzevii is in GenBank (GU299177.1). The plasmids for cGAL driver (pHW393, plasmid no. 85583) and effector (pHW394, plasmid no. 85584) are available from Addgene. Source data for Figures 1, 2, 3 and Supplementary Figures 1 and 2 are available online. Author Contributions: H.W., J.L. and P.W.S. conceived the project. H.W. and J.L. performed the experiments, analyzed the data and wrote the paper. S.G. helped with molecular cloning and strain handling. E.M.S. devised the idea of trying Gal4p from yeast species with lower growth temperatures. C.M.C. and N.P. contributed reagents. The authors declare no competing financial interests.Attached Files
