Chromoplast biogenesis and carotenoid accumulation
Archives of Biochemistry and Biophysics, 2013Chromoplasts are special organelles that possess superior ability to synthesize and store massive amounts of carotenoids. They are responsible for the distinctive colors found in fruits, flowers, and roots. Chromoplasts exhibit various morphologies and are derived from either pre-existing chloroplasts or other non-photosynthetic plastids such as ...

Of chromoplasts and chaperones
Trends in Plant Science, 2007Chromoplasts are carotenoid-accumulating plastids found in many fruits and flowers. In a new paper, Li and colleagues show that the Or gene of cauliflower induces differentiation of beta-carotene-containing chromoplasts in the (normally non-pigmented) curd tissue.

Chromoplasts of Palisota barteri, and the molecular structure of chromoplast tubules
Planta, 1986Ripe, deep-red fruits of Palisota barteri contain tubulous chromoplasts which develop from unpigmented leucoplasts. These plastids contain, besides large spherical inclusion bodies, numerous osmiophilic globules which, in the course of ripening, frequently show transition states to tubular structures.

Chromoplast Differentiation: Current Status and Perspectives [PDF]
Chromoplasts are carotenoid-accumulating plastids conferring color to many flowers and fruits as well as to some tubers and roots. Chromoplast differentiation proceeds from preexisting plastids, most often chloroplasts. One of the most prominent changes is remodeling of the internal membrane system associated with the formation of carotenoid ...

SummaryChromoplasts are heterogeneous organelles and their carotenoids can be associated with several different structural elements including globules, tubules and membranes. In the flower petals of some species, carotenoids are absent or present only in trace amounts.

Ultrastructure of the chromoplasts in the carrot root
Journal of Ultrastructure Research, 1965The “crystalline” chromoplasts in the orange root of the carrot result from overproduction of carotene which is stored in sheets of lipoprotein. The sheets have a lamellar structure with a layer repeat of 200 A. These lamellar packets are highly birefringent and dichroic. They have a tendency to elongate in a direction which includes 18–20 degrees with
