Altered starch and lipid gene expression in PSR1 overexpression lines. Relative expression of selected starch metabolism genes (A and B) and selected lipid metabolism genes (C and D) in psr1:PSR1 complementation lines is shown compared with the wild type (WT; CC125) and psr1 (A and C) and in overexpression lines compared with the wild type (cw15; B and D) under high-P and low-P conditions at day 3. Expression of the mRNA transcripts by real-time PCR was determined relative to CBLP expression and is shown relative to the high-P-treated wild-type transcript. Each data point represents the mean ± se of three biological replicates each with three technical replicates. Asterisks denote significant differences (P < 0.05) from wild-type values and pound signs denote significant differences (P < 0.05) from psr1 values, both as determined by one-way ANOVA.
