Relative transcript abundance of antioxidants in pathosystem III.

<p>Vitamin B6 (<i>PDX1</i>, <i>PDX2</i>, <i>and PLR</i>), <i>GST</i>, and <i>CAT</i> genes of both pathogen <i>R</i>. <i>solani</i> AG1-IA (<i>RsolAG1-IA</i>) and the host, <i>Glycine max</i> (<i>GM</i>) in control and in infected and surrounding tissues at 18 HPI during <i>R</i>. <i>solani</i> AG1-IA and soybean leaves interaction. C: control; <i>R</i>. <i>solani</i> AG1-IA grown alone or soybean leaf confronted with sterile PDA. SNL: tissue surrounding necrotic lesion. NL: necrotic lesion. Asterisk indicates significant relative transcript abundance ratios between the control and interaction using least significant difference (LSD) test (<i>P</i> < 0.05). Fold change is calculated in relation to the control at 18 HPI. <i>PDX1</i> and <i>PDX2</i>: Pyridoxine biosynthesis genes, <i>PLR</i>: <i>PYRIDOXAL REDUCTASE</i>, <i>CAT</i>: <i>CATALASE</i>, <i>GST</i>: <i>GLUTATHIONE S-TRANSFERASE</i>.
