Carotenoid biotechnology in plants for nutritionally improved foods (2006, background): “Although it is possible that tomato CYCB might as well be a bifunctional enzyme capable of converting both lycopene to b-carotene and violaxanthin to neoxanthin, another NSY activity should exist in tomato, because neoxanthin is synthesized in mutants with a defective CYCB gene (Ronen et al. 2000).”
Development of a codominant CAPS marker for allelic selection between canary yellow and red watermelon based on SNP in lycopene β-cyclase (LCYB) gene (2007, background): “The orange colored tomato mutants Delta and Beta were shown to be affected by different lycopene cyclase genes ( Ronen et al. 1999, 2000 ).”
Carotenoid metabolism in plants. (2015, neutral): “The expression of chromoplastspecific b-LCY has been found to correlate with the accumulation of b-carotene and/or downstream xanthophylls in tomato and citrus (Ronen et al., 2000; Alquézar et al., 2009).”
Genetic Regulation of Fruit Development and Ripening (2004, background): “…gene, resulting in the prolycopene-accumulating orange fruit of the tangerine mutants (Isaacson et al., 2002), and overexpression and knockout mutations of the lycopene-b-cyclase gene, resulting in high-b-carotene Beta (B) and deep-red crimson fruit, respectively (Ronen et al., 1999, 2000).”
Wild Crop Relatives: Genomic and Breeding Resources (2011, background): “Both genes were mapped to the long arm of chromosome 6 (Zhang and Stommel 2000, 2001), and B was cloned (Ronen et al. 2000) (see also Sects.”
Improving plant breeding with exotic genetic libraries (2001, background): “An important gene that was introduced from the wild tomato species Lycopersicon pennellii is B , which increases the level of provitamin A (β-carotene) in the fruit by more than 15-fol”
Abscisic acid biosynthesis and catabolism. (2005, background): “Furthermore, mutations in the putative tomato NSY gene were later found to affect ß-carotene synthesis from lycopene, therefore proving that this gene encoded a LCYB isoform (90).”
Ethylene biosynthesis and action in tomato: a model for climacteric fruit ripening. (2002, background): “Null mutations in the B gene are responsible for the phenotype in og mutants (Ronen et al., 2000).”
