With a construct including 8 kb upstream of the first exon and the entire
unc-7 genomic region fused to YFP, UNC-7 expression was found, in addition to the sex muscles reported in Expr12407, in several mating circuit neurons (SPC, PCA, PCB, HOA, HOB, and unidentified ray neurons). Similar to previous studies (Starich et al., 2009; Yeh et al., 2009; Kawano et al., 2011), this reporter also expresses, in head ganglion neurons, several ventral chord neurons, and tail neurons of the hermaphrodite, in addition to few unreported pharyngeal neurons (I5, M2, I4, M3, and I1).
