Gene Details:

• Gene ID: Solyc07g056570
• Gene Symbol: SlNCED1
• Gene Name: 9-cis-epoxycarotenoid dioxygenase
• Genome: Tomato Genome version SL4.0
• Species: Solanum lycopersicum

Functional Descriptions:

• SlNCED1 and SlCYP707A2: key genes involved in ABA metabolism during tomato fruit ripening.
• Quantitative real-time PCR showed that VIGS-treated tomato fruits had significant reductions in target gene transcripts.
• Silencing SlNCED1 or SlCYP707A2 by VIGS significantly altered the transcripts of a set of both ABA-responsive and ripening-related genes, including ABA-signalling genes (PYL1, PP2C1, and SnRK2.2), lycopene-synthesis genes (SlBcyc, SlPSY1 and SlPDS), and cell wall-degrading genes (SlPG1, SlEXP, and SlXET) during ripening.
• These data indicate that SlNCED1 and SlCYP707A2 are key genes in the regulation of ABA synthesis and catabolism, and are involved in fruit ripening as positive and negative regulators, respectively.
• Fruit-specific RNAi-mediated suppression of SlNCED1 increases both lycopene and beta-carotene contents in tomato fruit.
• To study the regulation of carotenoid biosynthesis by ABA, the SlNCED1 gene encoding 9-cis-epoxycarotenoid dioxygenase (NCED), a key enzyme in the ABA biosynthesis, was suppressed in tomato plants by transformation with an RNA interference (RNAi) construct driven by a fruit-specific E8 promoter.
