Distribution of transcript levels of SlCPS, SlGA20ox1, -2, and -3, and SlGA3ox1 and -2 in different organs of tomato. Semiquantitative transcript analysis was carried out by RT-PCR, as described in “Materials and Methods,” using total RNA from roots (R), young leaves before flowering (YLp), young and old leaves from plants at flowering (YL, OL), young and old internodes (YI, OI), flowers (Fl), ovary at anthesis (O), stamens (St), sepals (Se), petals (Pe), and 20-d-old fruit (Fr). For each gene, figures below the blots mean normalized values of gene expression versus that of Actin (used as an internal control; flower expression set at 1.0). Data come from a representative experiment out of two biological replicates with similar results.
