Lutein and zeaxanthin are associated with chloroplasts or chromoplasts in plants.
Pollen carries half the genetic compliment to the prospective zygote but without the plastid component (chloroplasts and other chromoplasts) of the female ova so it contributes just a bit less or contributes differently than the ova.
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.
Chromoplasts are pigment organelles, as the name implies, but are specialized to synthesize and store carotenoid pigments (red, orange, and yellow) instead of chlorophyll.
Although its role is not completely understood, Or is known to be involved in proplastid differentiation and other non-coloured plastids into chromoplasts for carotenoid accumulation.
The final phase of differentiation is often characterized by the presence of chromoplasts in various tissues, including senescent leaves, fruit pulp, and petals (Ljubesic et al., 1991).
Photosynthesizing pigments in leaves are found in the chloroplasts, while the other pigments that fascinated Wang-Wei and are responsible for the bright colors in stems, trunks, flowers, and fruits are found in the chromoplasts. Plastids are thus the cellular structures responsible for the colors of deciduous forests.
Nevertheless, studies have shown that the thermal processing of tomatoes and its products--rich sources of lycopene--improve bioavailability, so that it breaks the cell wall and allows the extraction of lycopene from the chromoplasts (WILLCOX et al., 2003).
