Analysis of Chloroplast Movement and Relocation in Arabidopsis
Chloroplast photorelocation movement is essential for the sessile plant survival and plays a role for efficient photosynthesis and avoiding photodamage of chloroplasts. There are several ways to observe or detect chloroplast movement directly or indirectly. Here, techniques for the induction of chloroplast movement and how to detect the responses, as well as various points of attention and advice for the experiments, are described.
