Lignin and carbohydrate contents in rice roots under control conditions or infected with S. hermonthica at 4 dpi as estimated by pyrolysis-GCMS. Total lignin amount was calculated by summing up area values in each pyrogram of lignin-derived compounds except for 4-vinylphenol, 4-vinyl-guaiacol, and the analogous 2,6-dimethoxy-4-vinylphenol (4-vinylsyringol), whereas total carbohydrate amount was determined by summing up the area of 18 peaks derived from carbohydrates as listed in Supplemental Data Set S3. Values represent mean ± SE. Asterisks (*) indicate statistically significant differences (Student’s t test, P < 0.05) between control and S. hermonthica-infected plants.
