‘Simultaneous’ measurements of delayed luminescence and chloroplast organization in Acetabularia acetabulum

Abstract This paper reports results of ‘simultaneous’ measurements of chloroplast streaming and delayed luminescence of Acetabularia cells. We show that freezing in liquid nitrogen or incubation in chloroform affects significantly and rapidly both the organelle motility and delayed luminescence decay. Results suggest the idea that delayed luminescence is related to the integrity of the dynamic chloroplast organization.
