Studies on chloroplast development in Chlamydomonas reinhardtii II. Effects of interposed darkness on chlorophyll synthesis

Yoshihiro Matsuda

Department of Biology, Faculty of Science, Kobe University Kobe, Japan

Effects of an inserted dark incubation on light-induced chlorophyll synthesis in dark grown Chlamydomonai reinhardtii y-1 cells were studied. Chlorophyll synthesis in cells with the interposed dark incubation proceeded faster than that in cells without the dark incubation when it was inserted within 2.5 hr after the onset of illumination. Within this limit, the longer the initial illumination given, the shorter was the length of dark incubation required to obtain a maximum rate of chlorophyll synthesis. However, when the dark incubation was provided later than 2.5 hr, the rate of subsequent chlorophyll synthesis was reduced. Since cells responded to the dark treatment in different manners before and after the 2.5 hr point, this time was designated as the transition point. This 2.5 hr period corresponds to the length of the regular lag phase in chlorophyll synthesis under continuous illumination.

Based on these results, the nature of the previously postulated promoting factor (P-factor) in chlorophyll synthesis is discussed.
