Sm1 differentially modulates SAR and ISR-related genes in tomato but it is dispensable to induce almost all genes. Total RNA from roots (R) and leaves (L) of 14-day-old tomato plants inoculated with TvOE2.2 and TaKO2 along with the T. virens wild-type strain was extracted at 72 h post-inoculation and subjected to RT-qPCR. Non-Trichoderma inoculated (NT). Gray bars show relative expression in roots, whereas black bars represent relative expression in leaves. Expression profile of two tomato SAR-related genes (SlGLUA and SlPR-5), and four ISR-related genes (Slα-DOX1, SlCHI9, SlTLRP, and SlCEVI16) was determined. Actin gene SlTOM51 was used as housekeeping gene. Letter indicates statistically significant differences (analysis of variance, P < 0.0001, LSD range test < 0.05).
