Mean expression profile of the Lycopene pathway committed steps and significant differential enzymes.

PSY1 is the rate limiting step in the carotenoid biosynthesis pathway and the absence of LβCYC in the pathway increases the pool of lycopene from the pathway. A. psy1 RPKM expression values. B. Lβcyc1 RPKM expression values. C. psy1 leaf expression values with a different y-axis to discern standard error differences. D. Z-ISO leaf expression values. Table of annotations and accession numbers from Sol Genomics ITAG3.2. Error bars denote the standard error of sequenced expression values between 3 biological replicates.
