The role of carotenoid cleavage dioxygenases in the regulation of carotenoid profiles during maturation in citrus fruit [PDF]
Journal of Experimental Botany, 2006 To investigate the relationship between a carotenoid profile and gene expression for carotenoid cleavage dioxygenases, three citrus varieties that exhibit different 9-cis-violaxanthin levels in their juice sacs, Satsuma mandarin (Citrus unshiu Marc.; a variety accumulating a low level of 9-cis-violaxanthin), Valencia orange (Citrus sinensis Osbeck ...

Exploring the Diversity and Regulation of Apocarotenoid Metabolic Pathways in Plants
Frontiers in Plant Science, 2021 In plants, carotenoids are subjected to enzyme-catalyzed oxidative cleavage reactions as well as to non-enzymatic degradation processes, which produce various carbonyl products called apocarotenoids.

A cis-carotene derived apocarotenoid regulates etioplast and chloroplast development
eLife, 2020 Carotenoids are a core plastid component and yet their regulatory function during plastid biogenesis remains enigmatic. A unique carotenoid biosynthesis mutant, carotenoid chloroplast regulation 2 (ccr2), that has no prolamellar body (PLB) and normal ...

Role of carotenoid cleavage dioxygenase 1 (CCD1) in apocarotenoid biogenesis revisited [PDF]
Plant Signaling & Behavior, 2009 Oxidative tailoring of C(40) carotenoids by double bond-specific cleavage enzymes (carotenoid cleavage dioxygenases, CCDs) gives rise to various apocarotenoids. AtCCD1 generating C(13) and C(14) apocarotenoids and orthologous enzymes in other plants are the only CCDs acting in the cytosol, while the hitherto presumed C(40) substrate is localized in the

FEBS Open Bio, 2014 The biosynthetic processes leading to many of the isoprenoid volatiles released by tomato fruits are still unknown, though previous reports suggested a clear correlation with the carotenoids contained within the fruit.
