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
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

regulation of the expression of the carotenoid pathway genes by CRTISO, overview
metabolism
the enzyme is involved in the carotinoid pathway. In plants, carotenoid biosynthesis takes place via the central isoprenoid pathway of plastids. The pathway begins with the formation of phytoene from two molecules of geranylgeranyl diphosphate. Phytoene desaturase (PDS) and carotene desaturase (ZDS) introduce four double bonds into phytoene which then undergoes two symmetric dehydrogenation steps to yield zeta-carotene and lycopene, respectively. A specific enzyme, zeta-carotene isomerase (ZISO), is required for the cis-to-trans conversion to form tri-cis-zeta-carotene and another isomerase, carotenoid cis-trans isomerase (CRTISO), produces all-trans lycopene (commonly known as lycopene) from tetra-cis-lycopene (prolycopene). The all-trans-lycopene gets converted to alpha- or beta-carotene via cyclization of the terminal isoprene groups

physiological function

ZEBRA2 is involved in photoprotection in rice
physiological function
isozyme CoCRTISO1 is a key regulator of the accumulation of 5-cis-carotenoids in calendula petals
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
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
physiological function
overexpression in transgenic tobacco resultsin an increase of total carotenoids in the leaves with betaotene and lutein being the predominants
physiological function
carotenoid isomerase (CRTISO) catalyzing the lycopene formation, is regarded as a key enzyme for carotenogenesis in Phaeodactylum tricornutum, which can accumulate high-level carotenoids under optimal conditions. Isozyme PtCRTISO4 plays an additional regulatory role in terms of carotenoid accumulation
physiological function
the red color of tomato (Solanum lycopersicum) fruit comes from lycopene that is an effective natural antioxidant and is formed by enzyme carotinoid isomerase from prolycopene. Central role of carotenoid isomerase (CRTISO) in the cis to trans isomerization of prolycopene in tomato
physiological function
-
carotene cis-trans isomerase CRTISO catalyzes cis-trans isomerization of double bonds leading to the formation of all-trans-lycopene, which is the most powerful antioxidant among carotenoids and a substrate for subsequent synthesis of alpha-, beta-carotenes, and xanthophylls. The enzyme plays an important role in the carotenoid metabolism due to the wide variety of carotenoid-mediated pigmentation of the ripe fruit. Effect of the carotenoid content and activity of the carotene cis-trans isomerase CRTISO on tomato fruit colour, e.g. the green-fruited line L-Nesozrevayushchii, the yellow-fruited cv. Viking, the redfruited cv. Malinovyi Silach, and the brown-redfruited line L-176, overview. Quantitative real-time PCR does not reveal any strong correlation between the level of CRTISO gene expression and total carotenoids, which may be explained by a different quantity of metabolites preceding prolycopene

the enzyme can complement the Micro-Tom tangerine mutant, that is deficient for the carotenoid isomerase (CRTISO) gene. MT-t plants are successfully complemented with the CsCRTISO, and fruits show a carotenoid profile similar to the control, indicating that the Citrus allele indeed encodes an authentic functional carotenoid isomerase and that the signal peptide is functional in tomato. MT is silenced using an inverted repeat of a fragment from the Citrus CRTISO resulting in a stronger phenotype than MT-t. MT-t and MT silenced for CRTISO presented an overall decrease in transcript accumulation of all genes from the biosynthesis pathway. The expression of the Citrus CRTISO gene is able to restore the biosynthesis of carotenoids with the appropriate regulation in MT-t. The decrease in transcript accumulation in MT-t and MT-CRTISO-suppressed lines reinforces previous suggestions that transcriptional regulation of the carotenoid biosynthesis involves regulatory loops by intermediate products
additional information
compared to the wild-type, all three transgenic lines (T1-T3) of Nannochloropsis oceanica expressing the isozyme PtCRTISO4 exhibit higher levels of total carotenoid and violaxanthin. Quantitative RT-PCR demonstrates that phytoene synthase (NoPSY) rather than z-carotene desaturase (NoZDS) and lycopene beta-cyclase (NoLCYB) exhibits the highest upregulation, suggesting that PtCRTISO4 plays an additional regulatory role in terms of carotenoid accumulation. PtCRTISO4 overexpression increases C18:1n-9 but decreases C16:1n-7, implying that C18:1 may serve as a main feedstock for xanthophyll esterification in Nannochloropsis

targeted editing of tomato carotenoid isomerase reveals the role of 5' UTR region in gene expression regulation. Mutations are generated in the 5' UTR and exon 1 of the carotenoid isomerase gene using CRISPR/Cas9 expression via Agrobacterium-mediated transformation of tomato variety Periyakulam 1 (PKM1), transcriptome analysis and fruit phenotype analysis, overview. 5' UTR region deletion leads to a lower expression of CRTISO and to an intermediate phenotype, while the point mutation in exon 1 leads to a knockout loss of function of the CRTISO enzyme. Exon 1 mutants of T1 generation show a heritable tangerine fruit phenotype. Chlorophyll and carotinoid contents are reduced in the mutants compared to wild-type leading to a reduced pigmentation of the fruits
