Fig. 3From: The dopamine β-hydroxylase gene in Chinese goose (Anas cygnoides): cloning, characterization, and expression during the reproductive cycleExpression of gDBH in various tissues of Zhedong geese. Gene expression was determined by qPCR and is represented relative to GAPDH expression. Vertical bars represent the mean ± S.D. (n = 3). Different capital letters above error bars indicate highly significant differences between means (P < 0.01). Different lower case letters indicate significant differences (P < 0.05)Back to article page
