Figure 7From: The bHLH transcription factor SPATULA regulates root growth by controlling the size of the root meristemGA-responsive gene expression in the spt background. 7-day-old seedlings were used for gene expression experiments. For analysis of GA-responsive genes, seedlings were treated with 50μM GA or mock solution for three hours. (A) Expression of GA biosynthesis genes and GA receptor-encoding genes. (B) Expression of GA catabolism genes. (C, D) Expression of GA-responsive genes. Error bars indicate standard error of the means of expression.Back to article page
