Abstract

The chemical aspects of the circadian leaf movement known as "nyctinasty" are discussed in this paper. Each of the nyctinastic plants of five different genera so far examined contained a pair of factors, one of which induced leaf closure and another induced leaf opening. The relative contents of the closing and opening factors changed correlating with the nyctinastic leaf movement. The use of fluorescence-labeled and photoaffinity-labeled factors revealed that the factors bind to specific cells, the motor cells, present in the pulvini, and that the membrane fraction of the motor cells contained two proteins of 210 and 180kDa, which can bind to the factors.
