Identification of Plastoglobules as a Site of Carotenoid Cleavage
Carotenoids play an essential role in light harvesting and protection from excess light. During chloroplast senescence carotenoids are released from their binding proteins and are eventually metabolized.

β-Ionone: Its Occurrence and Biological Function and Metabolic Engineering
β-Ionone is a natural plant volatile compound, and it is the 9,10 and 9′,10′ cleavage product of β-carotene by the carotenoid cleavage dioxygenase. β-Ionone is widely distributed in flowers, fruits, and vegetables.

Selective inhibition of carotenoid cleavage dioxygenases: phenotypic effects on shoot branching. [PDF]
Members of the carotenoid cleavage dioxygenase family catalyze the oxidative cleavage of carotenoids at various chain positions, leading to the formation of a wide range of apocarotenoid signaling molecules. To explore the functions of this diverse enzyme family, we have used a chemical genetic approach to design selective inhibitors for different ...

Identification of Carotenoid Cleavage Dioxygenases from Nostoc sp. PCC 7120 with Different Cleavage Activities [PDF]
Carotenoid cleavage dioxygenases (CCDs) are a class of enzymes that oxidatively cleave carotenoids into apocarotenoids. Dioxygenases have been identified in plants and animals and produce a wide variety of cleavage products. Despite what is known about apocarotenoids in higher organisms, very little is known about apocarotenoids and CCDs in ...

Carotenoid cleavage dioxygenase (CCD) is the key enzyme for carotenoid cleavage, and the products of carotenoid cleavage regulate the ability of plants to stress. In this paper, six CCD genes were obtained from Morus notabilis (Mn) by reverse transcription-polymerase chain reaction (RT-PCR) and we classified them into three subgroups based on gene ...

Genes involved in the synthesis and signaling pathway of strigolactone, a shoot branching inhibitor
Branching is an important step in higher plant development, which not only determines the configuration of the plant directly, but also affects its adaptability to the environment. The interactions between hormones, genes, environmental and other factors
