GFP expressed in all cholinergic neurons. rt449 was created by CRISPR editing of the cognate glycine codon in C. elegans sod-1 to create a disease model for human mutation SOD1 G93A.

This strain contains rt449, which is sod-1[G93AC], while rt451 is sod-1[G85RC] and rt448 is the wild-type control for both.
