Example sentencesExamples
- To determine the robustness of these interlinked chromoplasts, protoplasts were made from ripe pericarp fruit tissue and examined for chromoplast-associated GFP fluorescence.
- Conversion of chloroplasts to chromoplasts occurs well before flower opening and thus before the reproductive function of the flower commences.
- As ripening progresses, fruit colour changes from green to red as chloroplasts are transformed into chromoplasts, chlorophyll is degraded and carotenoids accumulate.
- Although control of gene expression at the transcriptional level is a key regulatory mechanism controlling carotenogenesis in chromoplasts, it is not the only one.
- In ripening fruit, chloroplasts develop into chromoplasts and there are large changes in stromule number and morphology, particularly in the inner mesocarp cells.
Origin
Late 19th century: from chromo-2 'colour' + Greek plastos 'formed'.
