Expression profiles defining the Principal Component 1 for transcriptome of inflorescence development.

<p>A: Expression profiles of the transcripts with positive or negative component score values higher than 3. Each single line represents the average of mean-centered expression values for an individual transcript. B: Functional categories over-represented in each cluster. Color code is the same as in A. Absolute values of the log₁₀ transformed <i>P</i>-values were used for the bar diagram representing statistical signification, only categories with <i>P</i>-values <0.05 were shown.
