WebIntroduction. The chloroplast, a well-known plastid found in all photosynthetic plant cells, is the central organelle providing plants with foods and energy in the form of sugar or starch by photosynthesis (Jarvis and Lopez-Juez, 2014).Chloroplast turnover plays a critical role in plastid transition (e.g., proplastid to chloroplast) and nutrient mobilization (e.g., carbon … Web1. Prepare 1 mL 40% Percoll cushions in 1.5 mL microcentrifuge tubes.. 2. Gently layer chloroplast suspension from the import assay over Percoll. If import volume exceeds 400 μL, use multiple cushions.. 3. Centrifuge at 2000 × g, 4°C for 5 min. Intact chloroplasts will pellet; broken chloroplasts will not enter the gradient.. 4. Remove broken chloroplasts by …
