Fig 5 — a. Real time quantitative (Q)-PCR validation (upper panel) of genes implicated in auxin biogenesis or transport identified in microarray analysis (lower panel) as being altered in tink/ibr5-6 mutants compared to wild-type flowers. Values in Q-PCR analysis are shown as mean ± SEM with expression levels normalized to that of the TUB6 gene for 3 biological and 3 technical replicates. b. Quantitation of bulk polar IAA transport in stem segments of the indicated genotypes. Values are represented as mean ± SEM of radiolabel transported (in cpm). There is no significant difference between wild-type and the respective ibr5 mutant alleles. At least 18 stem segments were assayed per genotype.
