pax1-1 mutant phenotypes in wild-type and axr3 backgrounds. (a) Wild type, (b) pax1-1, (c) axr3-1 and (d) axr3-1 pax1-1 shoot morphology at maturity. Bar = 5 cm. (e) Wild type and (f) pax1-1 seedling 6 days after germination (dag). Bar = 1 cm. (g) Wild type and (h) pax1-1 flower. The elongated carpel phenotype seen in pax1-1 is also observed in axr3 pax1-1 double mutants. Bar = 0.5 mm. (i) Wild type, (j) pax1-1, (k) axr3-1 and (l) axr3-1 pax1-1 root hairs 3 dag. In pax1-1 and axr3-1 pax1-1, multiple roots hairs arise from a single root epidermal cell. Bar = 250 μm. All axr3-3 pax1-1 phenotypes were qualitatively similar to axr3-1 pax1-1, showing suppression of axr3 phenotypes by pax1-1.
