The effects of LeTLP1 overexpression on the resistance of L. edodes to T. atroviride infection. (A) Relative expression levels of LeTLP1 in the parent isolate Y55 of L. edodes and its LeTLP1-overexpression transformants; 1–10: Y55_OE_1, 2, 3, 4, 5, 6, 7, 8, 9, 10. (B) The confrontations of the LeTLP1 overexpression transformants (Y55_OE_3 and Y55_OE_10) and the susceptible Y55 L. edodes against T. atroviride (92-1) were observed on the 15th day after inoculation with T. atroviride. (C) Infection rates (LT:LL) of T. atroviride in the susceptible Y55 strain and the LeTLP1-overexpression transformants. (D) Relative expression levels of LeTLP1 in the parent isolate Y3334 of L. edodes and its LeTLP1-silenced transformants; 1–10: TLP1-Ri-1, 2, 3, 4, 5, 6, 7, 8, 9, 10. (E) The confrontations of the LeTLP1-silenced transformants (TLP1-Ri-3, TLP1-Ri-8, and TLP1-Ri-9) and the susceptible L. edodes (Y55) against T. atroviride (92-1) were observed on the 15th day after inoculation with T. atroviride, respectively. (F) Infection rates (LT:LL) of T. atroviride in the resistant strain Y3334 and LeTLP1 RNAi transformants. Bars denote the standard error of the mean of three replicates in each of three independent experiments. ** indicates a statistically significant difference (p < 0.01). Green arrows refer to mycelial plugs of L. edodes; white arrows refer to mycelial plugs of T. atroviride. Red arrows represent LT (the length of T. atroviride mycelia covering L. edodes), as described by Wang et al. (2018) [32].
