FIGURE 2.

Time-course of defense related gene expression in leaves and roots of watermelon. Gene expression was assayed by qRT-PCR at 3, 7, and 14 days post inoculation (dpi). The primers used for transcript analysis are listed in Supplementary Table S1. Data are the means ±SD of three biological replicates. Means denoted by the same letter did not significantly differ at p < 0.05 according to Duncan’s multiple range test. CK, white light without M. incognita infection; RL, red light without nematodes infection; RKN, white light with M. incognita infection; RL+RKN, red light with M. incognita infection.
