Gene expression stabilities of candidate reference genes.

<p>Average expression stabilities (M) of the candidate reference genes in (A) flower buds (25 genes) and (B) leaves (26 genes) as estimated by geNorm. Small M values indicate high stability. M values for most genes were below 0.5, indicating high expression stability <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0092893#pone.0092893-Taylor2" target="_blank">[36]</a>. Traditional reference genes are indicated in bold.
