TEP1 and infection: For two LeTLP1 RNAi strains (TLP1-Ri-3 and TLP1-Ri-8), deep black compounds were generated in the interaction zone between the mycelia of the LeTLP1 RNAi strains and the T. atroviride strains (Figure 5E), and the infection rates (LT:LL) of T. atroviride in the mycelia of L. edodes increased dramatically compared to those in the parent isolate Y3334 (Figure 5F).
