  1. Fourier transform infrared spectroscopy analysis of root cell walls from control and V. dahliae-inoculated LA3030 (susceptible) and LA3038 (resistant) tomato plants at 16 and 28 days post-inoculation, with assignment of peak wave number to functional groups. C: control plants; I: inoculated plants; dpi: days post-inoculation
