Figure 1From: Identification of potential transcriptional regulators of actinorhizal symbioses in Casuarina glauca and Alnus glutinosaExpression profiles of potential transcription factors in Casuarina glauca and Alnus glutinosa nodules compared to non-inoculated roots. Purple and orange bars represent putative transcriptional regulators from C. glauca and A. glutinosa respectively. Bars represent fold change in nodules compared to non-inoculated roots (Fold change or FC ≥ 2 or ≤ −2 and p-value < 0.01). Transcription factors induced and repressed in C. glauca and A. glutinosa nodules are highlighted in tanned brown and light pink respectively. Astericks identify the genes confirmed by Q-PCR. Red triangles identify the transcription factors (CgZF1 and AgZF1) most strongly induced in the nodules.Back to article page
