    5.2.1.13 | malfunction |
in the wild type, 7 days after the breaker stage, 75% of total carotenoids in ripe fruit consist of all-trans-lycopene and more than 15% are lycopene precursors (neurosporene, zeta-carotene, phytofluene, and phytoene). In fruit of the mutant tangerine3183, the major carotenoid accumulates is prolycopene, whereas lycopene precursors, mostly in the cis configuration, constitute the rest of the carotenoids |

| 5.2.1.13 | malfunction |
mutation of the ZEBRA2 gene results in the accumulation of all-trans-lycopene precursor, prolycopene (7,9,7',9'-tetracis-lycopene), in dark-grown zebra2 tissues. Light-grown zebra2 mutant exhibits the characteristic zebra phenotype and decreases level of lutein |

the orange-flowered calendula is a carotenoid isomerase (crtiso) loss-of function mutant that impairs the cis-to-trans conversion of 5-cis-carotenoids |

| 5.2.1.13 | malfunction |
the orange-flowered calendula is a carotenoid isomerase (crtiso) loss-of function mutant that impairs the cis-to-trans conversion of 5-cis-carotenoids. A Gly-to-Glu amino acid substitution at position 450 in CoCRTISO1-ORb abolishes enzyme activity completely |

| 5.2.1.13 | malfunction |
the orange-flowered calendula is a carotenoid isomerase (crtiso) loss-of function mutant that impairs the cis-to-trans conversion of 5-cis-carotenoids. Deletion of Cys-His-His at positions 462-464 in isozyme CoCRTISO1-ORa abolishes enzyme activity completely |

| 5.2.1.13 | physiological function |
isozyme CoCRTISO1 is a key regulator of the accumulation of 5-cis-carotenoids in calendula petals |

| 5.2.1.13 | physiological function |
mutation in Mhz5 blocks carotenoid biosynthesis, reduces abscisic acid accumulation, and promotes ethylene production in etiolated seedlings. Mutation or overexpression of Mhz5 alters the expression of ethylene-responsive genes. The Mhz5-mediated abscisic acid pathway acts downstream of ethylene signaling to inhibit root growth |

| 5.2.1.13 | physiological function |
mutation leads to moderately increased tiller numbers, semi-dwarfism and leaf variegation. Prolycopene accumulates while all-trans-lycopene is barely detectable in the dark-grown Mit3 mutant seedlings. Content of lutein and beta-carotene and of 2'-5-epi-5-deoxystrigol is significant in the mutants |
