The development of chromoplasts from chloroplasts during ripening of Valencia oranges was followed with the electron microscope. The chloroplasts in the young, green fruit of Valencia were similar in structure to those in leaves of other plants. During ripening, there was a breakdown of the internal membrane system, the grana-fretwork system, and large, osmiophilic globules were formed. These globules apparently formed from breakdown products of the granal membranes as well as from carotenoids… Expand

TLDR
Even in the very late stages of chromoplast differentiation, the crystals and remaining stroma are surrounded by an intact plastid envelope, which can be consistently demonstrated at the ultrastructural level. Expand
Ultrastructural development of plastids in cherry peppers during fruit ripening
TLDR
The fine structure of plastids in the fruit of cherry peppers was studied during the various stages of ripening, and the relationship between the development of chromoplasts and the increase and decrease of some pigments is discussed. Expand
The development and ultrastructure of lycopene bodies in chromoplasts ofLycopersicum esculentum
SummaryLycopene bodies are developed in tomato chromoplasts at temperatures permitting synthesis of lycopene. Their appearance seems to be in correlation with the formation of special rigidExpand
Ultrastructural aspects of petal development inCucumis sativus with particular reference to the chromoplasts
TLDR
Changes in fine structure in petals of cucumis have been followed from an early green stage, through maturity, to a senescent dark yellow stage, corresponding to the senescence syndrome found in cucumber leaves and cotyledons. Expand
Ultrastructural changes of chloroplasts in detached parsley leaves yellowing in darkness and the influence of kinetin on that process
TLDR
Kinetin inhibits the yellowing process of parsley leaves and the degeneration of plastids, and experiments to reverse this process failed. Expand
[The fine structure of chromoplasts from plasmochromous perigon-leaves of Tulipa].
TLDR
The chromoplasts of yellow perigon leaves of Tulipa derive from the young chloroplasts present in the bud stage and the function of the petal plastoglobuli as stores for the chromoplast lipids such as plastidquinones and carotenoids is discussed. Expand
CHROMOPLASTS OF TOMATO FRUITS. II. THE RED TOMATO
TLDR
Comparisons of the mature chromoplasts of the normal red tomato with those of other pigment lines indicate that differences in carotenoids markedly affect ultrastructure, and the relationship between lycopene and chromoplast structure and the effect of genes controlling fruit pig is determined. Expand
Die Feinstruktur der Chromoplasten in plasmochromen Perigon-Blättern von Tulipa
TLDR
The chromoplasts of yellow perigon leaves of Tulipa derive from the young chloroplasts present in the bud stage and the function of the petal plastoglobuli as stores for the chromoplast lipids such as plastidquinones and carotenoids is discussed. Expand
CHROMOPLAST ULTRASTRUCTURE AS AFFECTED BY GENES CONTROLLING GRANA RETENTION AND CAROTENOIDS IN FRUITS OF CAPSICUM ANNUUM
TLDR
The isogenic material used in this study, with genes differing only for fruit color and carotenoid composition, permits a more controlled examination of chromoplasts. Expand
Scanning electron microscopic study of modified chloroplasts in senescing broccoli florets
TLDR
Results indicate that the degradation of chloroplasts in broccoli florets progresses systematically, with the final product being colored particles, which are visible in yellow broccoli sepal cells. Expand

TLDR
An investigation of the transformation of chloroplasts into the spindle-shaped chromoplasts containing submicroscopic filaments has been undertaken and the origin and development of these filaments, which present some morphological resemblance to filamentous virus particles, is discussed. Expand
