Leaves in natural plant canopies experience a highly variable light environment over the course of a day. Nevertheless, it has not been clarified what factors regulate photosynthesis in natural environments where irradiance often fluctuates. Dr. Yamori and Prof. Makino (Laboratory of Plant Functional Nutrition) discovered that Rubisco activase is critical for accelerating the activation rate of Rubisco and thus CO2 assimilation, in a dynamic light environment. This finding has been published in The Plant Journal in September, 2012, as “the Featured Article of that issue”.
Yamori W., Masumoto C., Fukayama H. & Makino A. (2012) Rubisco activase is a key regulator of non steady-state photosynthesis at any leaf temperature and, to a lesser extent, of steady-state photosynthesis at high temperature.
