Caption: F-box proteins negatively control plant phenols' production. Compared to the normal growing plants (left panels), increasing the action of F-box proteins in plants results in lower levels of (poly)phenols in their seed coats (upper right, pale yellow seeds) and lower amounts of lignin in plant stem (middle right, weaker violet-red staining); whereas turning-down F-box action leads to more phenol pigments (purple) in basal stem and leaves (lower right).
