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.

Chromoplasts--the last stages in plastid development
The International Journal of Developmental Biology, 1991The results of investigations on the development of chromoplast fine structures in various plants are reviewed. Emphasis is placed on the specific pigment-containing structures and their development during chromoplast formation. There is a large variety of these structures, although four fundamental types can be discerned.

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.

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.

Galactolipid synthesis in chromoplasts in vitro
Planta, 1979Isolated chromoplasts from Narcissus pseudonarcissus flowers contain: a fatty acid synthesizing system; acyl-CoA synthetase (EC 6.2.1.3); glycero-phosphate acyltransferase (EC 2.3.1.15); acylglycero-phosphate acyltransferase; phosphatidate phosphatase (EC 3.1.3.4); diacylglycerol galactosyltransferase (EC 2.4.1.46); and diacylgalactosylglycerol ...

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

The properties of plant-derived precipitates of watermelon lycopene were examined in aqueous sodium dodecyl sulfate (SDS) as part of an ongoing effort to develop simpler, more economical ways to quantify carotenoids in melon fruit. Levels of SDS >0.2% were found to increase the water solubility of lycopene in the state in which it was isolated from ...

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 ...

The ultrastructure of chromoplast development in red tomatoes
Journal of Ultrastructure Research, 1968Plastid morphogenesis in ripening red tomato fruit tissues has been studied by light and electron microscopy. Color changes of the fruit flesh result from the metamorphosis of chloroplasts 3–6 μ in diameter into chromoplasts 15–48 μ in length and 1–2 μ in diameter, which accumulate lycopene as the major pigment component.

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.
