Webb20 nov. 2024 · Phytoene synthase (PSY) is the rate-limiting step in carotenoid biosynthesis, and accordingly subjected to a number of regulatory mechanisms at various levels, including transcriptional, posttranscriptional, and posttranslational. WebbPhytoene biosynthesis is the first committed step in carotenoid biosynthesis, and has long been considered a ‘bottleneck’ in the pathway. Except for Arabidopsis, most other plant species express multiple functionally redundant copies of phytoene synthase ( PSY ), although different PSY genes appear to be differentially expressed and regulated.
