Action-spectra studies of the photocontrol of seed germination, flowering, and stem elongation showed that a reversible photochromic pigment plays a dominant role in the control of plant development (1). The pigment, now called phytochrome, was measured photometrically in dark-grown seedlings and was extracted as a soluble protein (2). Phytochrome has not been detected photometrically in the leaves of green plants even though physiological evidence for its presence is abundant. The present paper reports the presence of phytochrome in partially purified extracts of green plants.
