*4.5. Hormone Content Quantification*

The endogenous hormone contents (SA, JA, and ET) was determined for *R. solani* infected *A. philoxiroides* and *A. sessilis*. Fungal inoculations were performed on four-week old plants (as described above). Samples collected at different time intervals (0, 6, 12, 24, 48, 72, and 96 hpi) were subjected to hormone quantification by Lengton Bio. Tec. Co., Ltd. (Shanghai, China) using the ELISA method [97]. The 0 hpi time interval refers to the un-inoculated control samples.
