Two distinct blue-light responses regulate epicotyl elongation in pea
Blue light induces a long-term suppression of epicotyl elongation in red-light grown pea (Pisum sativum L.) seedlings. The fluence-response characteristics are bell-shaped, indicating the possibility of two different blue-light responses; a lower fluence response causing suppression and a higher flu...

description | Blue light induces a long-term suppression of epicotyl elongation in red-light grown pea (Pisum sativum L.) seedlings. The fluence-response characteristics are bell-shaped, indicating the possibility of two different blue-light responses; a lower fluence response causing suppression and a higher fluence response alleviating the suppression. To determine if two responses are in effect, we have grown pea seedlings under dark conditions hoping to eliminate one or the other response. Under these growth conditions, only the lower fluence portion of the response (suppression of elongation) is apparent. The kinetics of suppression are similar to those observed for the lower fluence response of red-light-grown seedlings. The response to blue light in the dark-grown seedlings is not due to the excitation of phytochrome because a pulse of far-red light large enough to negate phytochrome-induced suppression has no effect on the blue-light-induced suppression. Furthermore, treatment of the dark-grown seedlings with red light immediately prior to treatment with high fluence blue light does not elicit the higher fluence response, indicating that the role of red light in the blue high fluence response is to allow the plant to achieve a specific developmental state in which it is competent to respond to the higher fluences of blue light |
