Fig. 8From: Evolutionary characterization and transcript profiling of β-tubulin genes in flax (Linum usitatissimum L.) during plant developmentClustergram of differential β-tubulin gene expression in stem sections and hypocotyls. Color ranges from green to red, through black, according to the manitude of relative gene expression, as shown in the scale bar. Targets are clustered according to their similarity in the expression patternBack to article page
