Relative differential expression of flax β-tubulin genes in stem sections and hypocotyls. Relative transcript levels of the 14 flax β-tubulin genes, normalized to the geometric mean of two reference genes, as evaluated by real-time qPCR in stem sections (a and c) and hypocotyls (b and d). Expression levels, grouped by sample and relative to the avarage expression of each target, are shown in panels a and b. In panels c and d, transcript amounts are grouped by sample and normalized to a control sample: the apex in panel c and the DAS 3 sample in panel d. A Log2 scaling was used for the y axis
