Restriction Enzyme Analysis of Tomato Chloroplast and Chromoplast DNA

Characterization of Avian Pasteurella multocida Isolates by Protein Profiles and Restriction Enzyme Analysis of Chromosomal DNA

Characteristics of the tomato chromoplast revealed by proteomic analysis.

Chromoplasts are non-photosynthetic specialized plastids that are important in ripening tomato fruit (Solanum lycopersicum) since, among other functions, they are the site of accumulation of coloured compounds. Analysis of the proteome of red fruit chromoplasts revealed the presence of 988 proteins corresponding to 802 Arabidopsis unigenes, among which 209 had not been listed so far in plastidi...

Daffodil Chromoplast DNA: Comparison with Chloroplast DNA, Physi cal Map, and Gene Localization

In daffodil, development of chloroplasts or chromoplasts is not accompanied by plastid DNA modification. This has been shown by comparing the fragment pattern of different restriction endonucleases, and by the lack of methylation of CCGG sequences. A physical map has been constructed for the plastome using the restriction endonucleases Sal I, Pst I, and Bgl I. The fragments containing the genes...

Apparent Identity of Chromoplast and Chloroplast DNA in the Daffodil, Narcissus pseudonarcissus

Although chromoplasts and chloroplasts are mor­ phologically and functionally very different, it has been shown in certain plants and under certain con­ ditions, that they are interconvertible [see 1 5]. One could then expect such plastids to contain, at least qualitatively, the same plastome. It appears questionable, however, whether this applies to all plastid types. For example, FreyWyssling...

Plastid transcriptomics and translatomics of tomato fruit development and chloroplast-to-chromoplast differentiation: chromoplast gene expression largely serves the production of a single protein.

Plastid genes are expressed at high levels in photosynthetically active chloroplasts but are generally believed to be drastically downregulated in nongreen plastids. The genome-wide changes in the expression patterns of plastid genes during the development of nongreen plastid types as well as the contributions of transcriptional versus translational regulation are largely unknown. We report her...
