Chloroplast to chromoplast transition in tomato fruit: spectral confocal microscopy analyses of carotenoids and chlorophylls in isolated plastids and time-lapse recording on intact live tissue [PDF]
Annals of Botany, 2011 During evolution, chromoplasts have emerged as plastid structures which accumulate pigments to facilitate flower pollination and seed dispersal of fleshy fruit.

Characteristics of the tomato chromoplast revealed by proteomic analysis [PDF]
Journal of Experimental Botany, 2010 Chromoplasts are non-photosynthetic specialized plastids that are important in ripening tomato fruit (Solanum lycopersicum) since, among other functions, they are the site of accumulation of coloured compounds.

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.

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

Absence of ribosomes in Capsicum chromoplasts
Planta, 1988Ribosome development was followed by electron microscopy and gel electrophoresis of ribosomal (r)RNAs in the plastids of fully expanded fruits of Capsicum annuum L. during ripening. Chloroplasts from young Capsicum leaves were used as a structural and electrophoretic standard.

Properties of isolated carrot chromoplasts
Experimental Cell Research, 1954Abstract The carotene content of the chromoplasts of carrots varies from 20 to 56 per cent. The pigment-free portion (“stroma”) contains approximately 58 per cent ether and alcohol soluble matter, 22 per cent proteins and 6 per cent ash. 0.83 per cent lipid-P, corresponding to 21 per cent phospholipids, 0.4 per cent ether soluble Ca and 0.04 per cent

Chlorophyll synthetase in chlorophyll-free chromoplasts
Plant Cell Reports, 1981A considerable incorporation of [1-(14)C]isopentenyl diphosphate into chlorophyll in chromoplast preparations from daffodil flowers (Narcissus pseudonarcissus L.) was observed when exogenous chlorophyllide a was added. The enzyme chlorophyll synthetase showed properties of a peripheral membrane protein.
