    1.14.15.24 | malfunction |
a A709G mutation in the beta-carotene hydroxylase gene results in accumulation of beta-carotene and conversion of red to orange color in pepper fruit |

| 1.14.15.24 | malfunction |
in the homozygous b1 b2 double mutant both beta-hydroxylase activities are eliminated, but beta-ring-hydroxylated xanthophylls (L, V, and N) still are synthesized, albeit at lower levels than in ecotype Wassilewskija or in either single mutant. Xanthophylls N and V are reduced by 90 and 65%, respectively, and there is a 30% increase in xanthophyll L relative to ecotype Wassilewskija. As with the single beta-hydroxylase mutants, beta-carotene is unchanged relative to the wild type and beta-cryptoxanthin does not accumulate |

| 1.14.15.24 | malfunction |
knock-out of the gene reduces lutein and increases alpha-carotene, contributing to sensitivity to intense light |

| 1.14.15.24 | malfunction |
knockout of DSM2 influences the transcript levels of stress-related basic leucine zipper transcription factor genes |
716602 |
| 1.14.15.24 | malfunction |
mis-expressing of the individual hydroxylases can impact carotenoids metabolic flux, with the effect of AtB1 over-expression on beta-carotene metabolism being the most pronounced |

| 1.14.15.24 | malfunction |
the chy1chy2 double mutant shows reduced conversion of beta-carotene into beta-beta-xanthophylls |

| 1.14.15.24 | malfunction |
the homozygous b1/b2 double mutant does not show obvious growth defects and though beta-carotene-derived xanthophylls are reduced to 20% of wild type levels (much more than either b1 or b2 single mutant), the full complement of alpha- and beta-carotene-derived xanthophylls is still synthesized, albeit beta-carotene-derived xanthophylls are produced at lower levels in the double mutant |

| 1.14.15.24 | metabolism |
a key regulatory enzyme in the beta-beta-branch of carotenoid biosynthesis |

| 1.14.15.24 | metabolism |
CrtZ is one of ratelimiting enzymes for astaxanthin ((3S,3'S)-3,3'-dihydroxy-beta,beta-carotene-4,4'-dione) production |
