Fruit developmental landmarks superimposed with shape changes controlled by SUN. (A) Fruit landmark stages are color coded and indicated above the graph. Fruit shape index (length/width ratio, Y-axis) is shown as a function of dpa (X-axis). The kinetics of fruit shape change is overlaid on the fruit developmental landmarks. The largest difference in fruit shape indices is achieved at fruit landmark 3 and 4, coinciding with the landmarks 4–16 cell and globular stage of the embryo. Data shown are mean (± se) from three inflorescences per plant and from five plants per genotype. (B) SUN expression in the developing fruit and flowers of LA1589 NILs as determined by Northern blot analysis. Tissues were harvested in days post anthesis (DPA) as indicated above the lanes. LA1589ee carries oval shaped fruit and the sun allele of Sun1642. LA1589pp carries round fruit and the sun allele of LA1589 which is wildtype.
