The adenosine triphosphate (ATP) content of Black Valentine bean seedlings and of the Avena coleoptile and mesocotyl has been investigated in relation to red (600 to 700 m mu ) and far-red (700 to 750 m mu ) radiant energy responses. The nucleotide phosphate and ATP contents of the leaves, hypocotyl hook, elongated portion of the hypocotyl, and roots of 6-day-old dark-grown bean plants were proportional to the protein content. No detectable differences in the ATP level could be measured upon irradiation of the bean hooks with either red or far-red radiant energy. Dinitrophenol (10/sup -4/ M) reduced the ATP level of hooks to approximately 50% of the level of control hooks. When exposed to red radiant energy, the dinitrophenol-treated hooks of bean plants responded to about 60% of the response induced in the control. The ATP levels in the coleoptile and mesocotyl of Avena also were not influenced by red light. These results are interpreted as indicating the ATP is required for a light-induced growth response to occur, but alteration of the ATP level by red, far-red irradiation is probably not the system regulated by the photoreaction.
