The results suggested that <italic>CitCCD4</italic> (for Carotenoid Cleavage Dioxygenase4) was a key gene contributing to the biosynthesis of β-citraurin. In the flavedo of Yamashitabeni-wase, the expression of <italic>CitCCD4</italic> increased rapidly from September, which was consistent with the accumulation of β-citraurin. In the flavedo of Miyagawa-wase, the expression of <italic>CitCCD4</italic> remained at an extremely low level during the ripening process, which was consistent with the absence of β-citraurin. Functional analysis showed that the CitCCD4 enzyme exhibited substrate specificity. It cleaved β-cryptoxanthin and zeaxanthin at the 7,8 or 7′,8′ position. But other carotenoids tested in this study (lycopene, α-carotene, β-carotene, all-trans-violaxanthin, and 9-cis-violaxanthin) were not cleaved by the CitCCD4 enzyme. The cleavage of β-cryptoxanthin and zeaxanthin by CitCCD4 led to the formation of β-citraurin. Additionally, with ethylene and red light-emitting diode light treatments, the gene expression of <italic>CitCCD4</italic> was up-regulated in the flavedo of Yamashitabeni-wase. These increases in the expression of <italic>CitCCD4</italic> were consistent with the accumulation of β-citraurin in the two treatments. These results might provide new strategies to improve the carotenoid contents and compositions of citrus fruits.</p></abstract><counts><page-count count="14"></page-count></counts></article-meta><notes><glossary><title>Glossary</title><def-list><def-item><term id="term1">CCD</term><def id="def1"><p>carotenoid cleavage dioxygenase</p></def></def-item><def-item><term id="term2">LED</term><def id="def2"><p>light-emitting diode</p></def></def-item><def-item><term id="term3">cDNA</term><def id="def3"><p>complementary DNA</p></def></def-item><def-item><term id="term4">RT</term><def id="def4"><p>reverse transcription</p></def></def-item></def-list></glossary></notes></front></pmc></record>Pour manipuler ce document sous Unix (Dilib)
