Genetic Interaction between TGH and AMP1.

(A) to (S) Development of 7-d-old seedlings ([A] to [E]) and 2-week-old adult plants ([L] to [O]) is severely affected in the tgh-1 amp1-1 double mutants. Genotypes are as indicated in the panel. All pictures are taken at comparable magnification, except (O), which is 10 times magnified. See the inset in (O) for the original size of the adult tgh-1 amp1-1 mutant in scale with the single mutants shown in (L) and (M). Growth impairment of the double mutant is reflected at the level of vascular development in seedlings ([F] to [K]) and cotyledons ([P] to [S]). Bars = 5 mm in (L) to (N) and 1 mm in (O).

(T) to (W) Vascularization in the cotyledons and leaves of cleared 10-d-old dark-grown seedlings.

(X) Quantitative analysis of rosette diameters of adult wild-type plants, single mutants, and the tgh-1 amp1-1 double mutant (n ≥ 10; bars and error bars represent means and standard deviations).
