Isolation and Composition of Chromoplasts from Tomatoes

Journal of Agricultural and Food Chemistry, 2005
The 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.

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.

Galactolipid synthesis in chromoplasts in vitro

Planta, 1979
Isolated 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 ...

Interaction of Sodium Dodecyl Sulfate with Watermelon Chromoplasts and Examination of the Organization of Lycopene within the Chromoplasts

Journal of Agricultural and Food Chemistry, 2006
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 ...

Biochemistry and Molecular Biology of Chromoplast Development

1995
Plant cells contain a unique class of organelles, designated the plastids, which distinguish them from animal cells. According to the largely accepted endosymbiotic theory of evolution, plastids are descendants of prokaryotes. This process requires several adaptative changes which involve the maintenance and the expression of part of the plastid genome,

Leucoplasts Mimicking Membranous Chromoplasts

Zeitschrift für Pflanzenphysiologie, 1980
Summary 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, 1968
Plastid 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, 2020
Plant 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.

Circular DNA in chromoplasts of Tulipa gesneriana

Planta, 1976
Circular DNA has been extracted from isolated globulous chromoplasts of Tulipa gesneriana L. The isolated DNA molecules occur in the form of "open circles" and have a contour length of about 43.6 μm, corresponding to a molecular weight of about 92 kdaltons.

Research progress on differentiation and regulation of plant chromoplasts

Molecular Biology Reports
Carotenoids, natural tetraterpenoids found abundantly in plants, contribute to the diverse colors of plant non-photosynthetic tissues and provide fragrance through their cleavage products, which also play crucial roles in plant growth and development.
