Leucoplasts Mimicking Membranous Chromoplasts
Zeitschrift für Pflanzenphysiologie, 1980Summary Leucoplasts of coronae of a variety of the daffodil ( Narcissus pseudonarcissus L.) with white flowers (cv. «Mount Hood») exhibit the same fine structural appearance as membranous chromoplasts of the wild type. Their concentric internal membranes are — except for the absence of carotenoids — virtually identical with chromoplast internal ...

Publisher Summary Plastids have many differentiation states, including proplastids, chloroplasts, amyloplasts, etioplasts, gerontoplasts, and chromoplasts. These various forms of organelles play very different roles and are mostly interconvertible. An exception is gerontoplasts, the terminal state of chloroplasts in senescent leaves. Chromoplasts are

Carotenoids drive chromoplast development
Science, 2020Plant Biochemistry Carotenoid-rich cellular structures called chromoplasts are a source of the rich reds and yellows in the fruits and flowers of plants. Similar to green, photosynthetic chloroplasts, chromoplasts derive from plastids but are distinct in structure and development. Llorente et al.

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.

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

Isolation of chromoplasts from carrots
Experimental Cell Research, 1956Abstract 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.

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.

Chlorophyllase activity in chlorophyll-free citrus chromoplasts
Plant Cell Reports, 1983Chromoplast fractions from mature, chlorophyll-less 'Valencia' orange (Citrus sinensis L. Osbeck) flavedo (= the outer coloured layer of citrus peel) showed considerable chlorophyllase activity. Acetone powders prepared from chromoplast fractions had 2.5× higher specific activity than those prepared from whole flavedo.

Isolation and Composition of Chromoplasts from Tomatoes
Journal of Agricultural and Food Chemistry, 2005The fruit of the tomato plant is composed of elongated tomato cells filled with organelles called chromoplasts (plastids). These plastids scattered throughout the cell are rich in nutrients, particularly protein (33%) and lipids (20%). They can be released from the cells by rupture of their cell membranes and then isolated.
