Glyceollin transcription factor GmMYB29A2 is a regulator of soybean resistance to Phytophthora sojae

RNA-seq was conducted on hairy roots of Williams 82 (W82) and imbibing seeds of Harosoy 63 (H63) upon treatment with the P. sojae wall glucan elicitor (WGE) at the times of maximum glyceollin biosynthesis. Imbibed seeds of H63 and Hairy roots of W82 were treated with WGE or H2O (mock) and at the time of maximum glyceollin accumulation after treatment (48 h and 24 h, respectively), total RNA was extracted for RNA-seq. WGE samples were compared to the mock to identify upregulated genes, then these were searched for common genes among the two tissue types.
