Cell chloroplast

Chloroplast transformation provides a valuable alternative platform to generate transgenic plants. In seed plants, chloroplast transformation will face greater challenges because it always contains 1,000–2,000 copies of the chloroplast genome and approximately 100 chloroplasts per mature leaf mesophyll cell (Golczyk et al., 2014).Chloroplasts are cell organelles present only in a plant cell and it includes: Stroma Inner membrane Outer membrane Thylakoid membrane Intermembrane Space
