Fig 5. Spatiotemporal expression profiles of transporter genes by quantitative real-time RT-PCR.

Expression analysis in different organs (A) and during flower development (B). Le, leaves; St, stems; Tu, tubes; Sp, sepals; Lm, limbs; Ps, pistils; Sm, stamens; S2, stage2; S4, stage4; S5, stage5; D0, day0; D1, day1; D2, day2; Sn, senescence. Relative expression levels are shown as fold change values. Results are mean ± SD of triplicates. The reference gene ubq was used to normalize the expression values. Similar expression profile was observed when ran1 was used as another reference gene (S3 Fig).
