Abstract
Chloroplast orientation in the green alga Mougeotia has been induced by unidirectional red or blue light, given continuously during one hour. In addition, part of the preparations obtained scattered strong far-red light simultaneously with the orienting light. This far-red light completely abolished the response to red light, consistent with phytochrome as the sensor pigment for orientation in Mougeotia. In blue light, however, the response was completely insensitive to far-red light, thus pointing to a different sensor pigment in the shortwavelength region.
