FIGURE 7:

Balancing and synthetic interactions between mec-7 neo and anti alleles. (A) TRN morphology of animals carrying C303Y R391H double mutations in mec-7. Arrowhead points to the absence of long ALM-PN. (B) R391H single mutation caused an anti phenotype with severely shortened TRN neurites. Arrows point to the premature termination of ALM-AN and PLM-AN. The lower panels show the excessive short sprouts growing out of PLM-AN or PLM cell body in mec-7(R391H) mutants. (C) Schematic diagram of ALM and PLM morphologies in mec-7 neo and anti single mutants, as well as their double mutants. (D) The positions of R391 (red) and C303 (yellow) mutated in the two alleles. (E) Overextension of PLM-PN and excessive neurite sprouting from PLM cell body in the mec-7(C303Y R391H) double mutants. The diagrams on the right illustrate the abnormal PLM morphology at the tail.
