(A) Effect of TMV infection and P. argentea extract on chlorophyll content (SPAD unit) of tomato plants under greenhouse conditions; (B) the relative accumulation level of the TMV-CP gene in different treatments of tomato plants at 21 dpi. T1: Mock-treated tomato plants; T2: tomato plants inoculated with TMV only; T3: tomato plants treated with P. argentea extract only, and T4: tomato plants treated with P. argentea extract 24 h before TMV inoculation. Columns represent the mean value from three biological replicates, and standard deviation (±SD) is shown in the bars. Columns with the same letter means do not differ significantly.
