A photoreceptor with characteristics of phytochrome triggers sporulation in the true slime mould Physarum polycephalum

FEBS Lett. 1995 Aug 14;370(1-2):146-8. doi: 10.1016/0014-5793(95)00820-y.

Abstract

Phytochrome is a ubiquitous photoreceptor in plants that controls a variety of responses to light, including gene expression, differential cell growth and intracellular movement of organelles. All phytochromes analysed so far are reversibly interconverted by light between an inactive and an active conformation, each of which has a different and characteristic absorbance spectrum. Based on photophysiological measurements we provide evidence, that a photoreceptor with these unique properties of phytochrome triggers sporulation in the true slime mould Physarum polycephalum.
