Carotene desaturation is linked to a respiratory redox pathway in Narcissus pseudonarcissus chromoplast
In Lycopersicon peruvianum, another anemophilous species, the pathway is the same but without the chromoplast
carotenoids pigments: Plant cell pigments: red, orange, and yellow lipid soluble pigments found embedded in the membrane of chloroplast and chromoplast
Characteristics of the tomato chromoplast
revealed by proteomic analysis.
These carotenoids, which are more lipophilic, are easily incorporated into chromoplasts
increasing the red color of fruits.
As a result, the researchers believe they may be able to use specific proteins to regulate the functions of chloroplasts -- such as the conversion of chloroplasts into highly-pigmented chromoplasts
during the ripening of fruit.
Red bell pepper Loose parenchyma cells with small red/orange chromoplasts
Lutein and zeaxanthin are associated with chloroplasts or chromoplasts
Carotenoids are organic pigments that naturally occur in the chloroplasts and chromoplasts
of plants and some other organisms, such as algae, some types of fungus and some bacteria.
