BBS-7::GFP restores phasmid dye-filling in <i>bbs-7(my13)</i> mutant animals.

Animals homozygous for the my13 allele do not take up fluorescent dye in their phasmids and exhibit abnormal dye-filling in the amphids (tailDyf) while wild-type (him-5(e1490) animals take up dye in both the amphids and phasmids. Some wild-type and bbs-7(my13) animals carrying the BBS-7::GFP extrachromosomal array are tailDyf. BBS-7::GFP restores phasmid dye-filling in bbs-7(my13) mutant animals.
