| Although control of gene expression at the transcriptional level is a key regulatory mechanism controlling carotenogenesis in chromoplasts, it is not the only one. |
| As ripening progresses, fruit colour changes from green to red as chloroplasts are transformed into chromoplasts, chlorophyll is degraded and carotenoids accumulate. |
| In ripening fruit, chloroplasts develop into chromoplasts and there are large changes in stromule number and morphology, particularly in the inner mesocarp cells. |
| Chromoplasts appear in the cells of leaves, flowers and fruits, and are predominantly responsible for the synthesis of pigments. |
| Plants store beta-carotene in chromoplasts, and beta-carotene bioavailability is affected by chromoplast structure in plant tissues, such as fruit flesh. |
| Chromoplasts are carotenoid-accumulating plastids found in many fruits and flowers. |
