The endogenous content of major defense and signaling related phytohormones (A–F) including abscisic acid (ABA), auxin (AUX), ethylene (ACC), methyl jasmonate (MeJA), salicylic acid (SA), over the course of this study (mock-inoculated and PM inoculated after 48h phi) PM infection of susceptible and resistant watermelon lines, over early stages of invasion in leaves. The bars represent the standard error obtained from triplicate samples. *, **, and *** represent significant differences at P < 0.05, P < 0.01, and P < 0.001 (t-test), respectively. An unpaired t-test (P ≤ 0.05) was applied for the test of significance in hormone concentration in both contrasting lines. ns, not statistically significant.
