UNC-130 acts as a repressor to specify glial fates. (A) Schematic diagram of UNC-130 constructs used in rescue experiments to determine domain function. Full-length UNC-130 is 333 amino acids in length. (B) The unc-130 promoter was used to drive expression of individual constructs (schematized in A) in the unc-130 mutant strain and extent of rescue was assessed. Percentage of animals expressing grl-18pro:YFP in zero, one or two ILsoD glia in each condition. Average number of cells marked per animal is listed under each condition. n=50 animals per condition. P-values were calculated by Fisher's Exact test.
