简介：
Overview
This article describes protocols for investigating the dynamics of chloroplast stromules, which are stroma-filled tubules extending from chloroplast surfaces. The methods aim to visualize stromule frequency using live cell confocal fluorescence microscopy and in vitro techniques with isolated chloroplasts.
