In tomato, carotenoids are important with regard to major breeding traits such as fruit colour and human health. The enzyme phytoene synthase (PSY1) directs metabolic flux towards carotenoid synthesis. Through TILLING (Targeting Induced Local Lesions IN Genomes), we have identified two point mutations in the Psy1 gene. The first mutation is a knockout(More)
Carotenoids are abundant in citrus fruits and vary among cultivars and species. In the present study, high performance liquid chromatography (HPLC) and real-time polymerase chain reaction (PCR) were used to investigate the expression patterns of 23 carotenoid biosynthesis gene family members and their possible relation with carotenoid accumulation in fresh(More)
