The opening of the hypocotyl hook in bean seedlings is due to a rapid elongation of cells on the inner side of the hook elbow. Red light promotes hook opening by inducing this cell elongation.Opening is inhibited by low concentrations of indoleacetic acid (IAA) and 2,4-dichlorophenoxyacetic acid (2,
Inhibitors of protein and RNA synthesis (cycloheximide, puromycin, chloramphenicol, and actinomycin D), as well as Co(++), induce opening of the hypocotyl hook of bean seedlings during the early stage of the opening period both in the darkness and red light. The response is transitory, however, comp
