Figure 5.

Expression profiles of TYRAAt1 and TYRAAt2 in different organs. Steady-state levels of TYRAAt1 and TYRAAt2 mRNAs were measured by quantitative real-time RT-PCR on total RNA from Arabidopsis organs (flowers [Flow.]; stems, siliques [Siliq.]; rosette leaves [Leav.]; roots; and dry mature seeds [Seeds]) using isoform-specific primers (Supplemental Table S1) as described in “Materials and Methods.” Data are the mean ± sd of three independent experiments performed. The amplification of actin cDNA has been used as internal standard of RNA integrity and cDNA preparation.
