Table 3 Changes in lignin content following V. dahliae inoculation.

From: The Ve-mediated resistance response of the tomato to Verticillium dahliae involves H2O2, peroxidase and lignins and drives PALgene expression

  1. Lignin content, measured by acetyl bromide, and monomeric composition, revealed by analysis of nitrobenzene oxidation, of root cell walls products from control and V. dahliae-inoculated LA3030 (susceptible) and LA3038 (resistant) tomato plants at 16 and 28 days post-inoculation. H-units: hydroxyphenyl units; G-units: guaiacyl units; S-units: syringyl units; CW: cell walls; dpi: days post-inoculation. Values followed by the same superscript letter are not significantly different from controls (P < 0.05)
