Circular DNA in Isolated Chromoplasts

Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 1974
Abstract Flower chromoplasts of Narcissus pseudonarcissus have been isolated in high purity and inte­ grity by a new procedure. From these chromoplasts circular DNA molecules in supercoiled form have been isolated and demonstrated by electron microscopy to have a contour length of about 44 μm (molecular weight about 92 x 106 daltons)

Of chromoplasts and chaperones

Trends in Plant Science, 2007
Chromoplasts 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.

Proteomic analysis of chromoplasts from six crop species reveals insights into chromoplast function and development. [PDF]

Journal of Experimental Botany, 2013
Chromoplasts are unique plastids that accumulate massive amounts of carotenoids. To gain a general and comparative characterization of chromoplast proteins, this study performed proteomic analysis of chromoplasts from six carotenoid-rich crops: watermelon, tomato, carrot, orange cauliflower, red papaya, and red bell pepper.

Chromoplasts of Palisota barteri, and the molecular structure of chromoplast tubules

Planta, 1986
Ripe, 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.

Ultrastructure of the chromoplasts in the carrot root

Journal of Ultrastructure Research, 1965
The “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

Chromoplast structures inThunbergia flowers

Protoplasma, 1996
The differentiation of tubulous chromoplasts in developing flowers of Thunbergia alata was studied by ultrastructural, pigment and protein analysis. The way of chromoplast formation in the mesophyll differed from that in the adaxial epidermis. While, in mesophyll cells, the chromoplasts were directly transformed into chromoplasts of the tubular type ...

Absence of ribosomes in Capsicum chromoplasts

Planta, 1988
Ribosome 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.

Isolation of chromoplasts from carrots

Experimental Cell Research, 1956
Abstract Procedures were described for the isolation of orange and red fractions of chromoplasts from carrots. The fractions showed wide variations in their content of carotene and probably represent different stages of development of the chromoplasts.

CHROMOPLASTS IN SOME CYCADS

New Phytologist, 1985
SummaryThe ripe seeds of some species of cycads are red in colour and contain chromoplasts: those in seeds of Cycas revoluta Thurb. and Macrozamia lucida L. A. S. Johnson belong to the tubulous class of chromoplast whereas those of Zamia purpurea sp.nov.
