Abstract: | Summary We analyzed the formation of thylakoids and grana during the development of pea chloroplasts, illuminated by white, red and blue low intensity light. The total length of granal and intergranal thylakoids, and the length of granal thylakoids per unit area of plastid section were measured. Initially the greatest increase in length of granal thylakoids and the highest incidence of grana with large thylakoid content occurred in red light. On the other hand, with illumination times of over 12 hours blue light appeared to be more efficient in stimulating grana formation and thylakoid growth. |
