Fig. (4) Rescue of the hypomorph by let-756 expressed under the control of its own promoter. let-756(s2613) unc-32(e189) worms (A) were transformed by the P_let-756::let-756 construct. (B) shows the phenotype of animals rescued by let-756 expressed in all body muscles. These animals resemble the unc-32 strain (C). Animals shown in (D) exhibit LET-756 expression in anterior muscles: development of the posterior part of the animal is impaired and reciprocally, animals shown in (E) and (F) exhibit LET-756 expression in posterior muscles and their anterior part is thinner than normal. The autofluorescence of the gut granules is visible in (A) and (C).
