Chromoplast Differentiation: Current Status and Perspectives [PDF]
Plant and Cell Physiology, 2010 Chromoplasts are carotenoid-accumulating plastids conferring color to many flowers and fruits as well as to some tubers and roots. Chromoplast differentiation proceeds from preexisting plastids, most often chloroplasts. One of the most prominent changes is remodeling of the internal membrane system associated with the formation of carotenoid ...

Chromoplast biogenesis in Chelidonium majus petals
Acta Societatis Botanicorum Poloniae, 2011 The differentiation of chromoplasts, with special emphasis on the formation and the organisation of chromoplast fibrils, was followed in the petals of the greater celandine, Chelidonium majus L.

Precursor uptake assays and metabolic analyses in isolated tomato fruit chromoplasts [PDF]
Plant Methods, 2012 Background Carotenoids are the most widespread group of pigments found in nature. In addition to their role in the physiology of the plant, carotenoids also have nutritional relevance as their incorporation in the human diet provides health benefits.

Neofunctionalization of Chromoplast Specific Lycopene Beta Cyclase Gene (CYC-B) in Tomato Clade. [PDF]
PLoS ONE, 2016 The ancestor of tomato underwent whole genome triplication ca. 71 Myr ago followed by widespread gene loss. However, few of the triplicated genes are retained in modern day tomato including lycopene beta cyclase that mediates conversion of lycopene to β ...

Proteomic analysis of chromoplasts from six crop species reveals insights into chromoplast function and development [PDF]
Journal of Experimental Botany, 2013 Chromoplasts are unique plastids that accumulate massive amounts of carotenoids. To gain a general and comparative characterization of chromoplast proteins, this study performed proteomic analysis of chromoplasts from six carotenoid-rich crops: watermelon, tomato, carrot, orange cauliflower, red papaya, and red bell pepper.

Pro-Vitamin A Biofortified Cavendish Banana: Trait Stability in the Field. [PDF]
Plant Biotechnol JABSTRACT Vitamin A deficiency (VAD), a major global health concern, has driven efforts to develop staple crops with enhanced pro‐vitamin A (pVA) content. Delivering meaningful nutritional benefits, however, requires technologies that maintain elevated carotenoid levels under field conditions. Previous proof‐of‐concept work demonstrated that pVA content

Transcriptome analysis in tissue sectors with contrasting crocins accumulation provides novel insights into apocarotenoid biosynthesis and regulation during chromoplast biogenesis [PDF]
Scientific Reports, 2018 Crocins, the red soluble apocarotenoids of saffron, accumulate in the flowers of Crocus species in a developmental and tissue-specific manner. In Crocus sieberi, crocins accumulate in stigmas but also in a distinct yellow tepal sector, which we ...
