WebJan 5, 2015 · Lycopene is cyclized by β-LCY and ε-LCY or β-LCY to produce α-carotene or β-carotene. These carotenes are further hydroxylated to produce xanthophylls (e.g. lutein and zeaxanthin). The cleavage of β-carotene branch by CCDs and NCEDs produces various volatiles (e.g. β-citraurin, etc.) and phytohormones (strigolactones and abscisic acid). WebJan 23, 2024 · Lycopene-β-cyclase (LCYB) catalyses the last step of β-carotene synthesis, and therefore plays a key role in this pathway. Overexpression of LCYB leads to increased tolerance to abiotic stresses (e.g. drought and salt) in tomato ( D’Ambrosio et al., 2004 ), Arabidopsis ( Chen et al., 2011 ), and sweet potato ( Kang et al., 2024 ).

WebDec 22, 2024 · Isomerization of prolycopene to red-colored lycopene is carried out by carotene isomerase ( CRTISO ). Lycopene is further metabolized to produce β-carotene, zeaxanthin, violaxanthin, and neoxanthin, which is catalyzed by two classes of lycopene beta cyclases ( LCY-bs, CYC-b ). WebJul 2, 2009 · Expression analysis of carotenoid biosynthetic genes among different genotypes and fruit developmental stages identified Actinidia lycopene beta-cyclase ( LCY-β) as the gene whose expression pattern appeared to be associated with both total carotenoid and beta-carotene accumulation. WebDec 1, 2001 · A full-length cDNA for lycopene beta-cyclase (LYC-b) was isolated from carrot (Daucus carota L.) roots by 5' and 3' RACE.
