Altered root growth response to ethylene of light-grown seedlings containing kinase-inactive versions of ETR1. A, Phenotypes of 7-d-old seedlings grown in the presence of 10 µL L−1 ethylene under continuous light. B, Root lengths of seedlings grown in the absence (black bars) or presence (white bars) of 10 µL L−1 ethylene. Values represent means ± sd (n > 12). wt, Wild type.
