Fig S1. The sense and antisense strand sequences of SlMAPK7 RNAi construct. a The sense strand sequence is shadowed for
construction of RNAi vector in gray, and the primer pairs are underlined. b The antisense strand sequence is shadowed, and the
primer pairs are underlined.
Fig S2. The cDNA sequence of SlMAPK7. Underlined oligonucleotides indicate the PCR primers. The initial codon ATG and the
termination codon TGA are boldfaced.

p35S::SlMAPK7-RNAi, lane 4, 5, 6: Antisense fragment of p35S::SlMAPK7-RNAi. b Lane 1, 2, 3: Over-expression fragment of
p35S:: SlMAPK7.

Fig S5. Detection of transgenic tomato plants by PCR amplification. M indicates DNA maker; lane 1-9 indicate the transgenic
tomato plants with pCAMBIA1301; lane 10 indicates negative control; lane 11 indicates positive control.
Fig S6. Detection of RNAi and overexpression transgenic tomato plants by PCR amplification. M indicates DNA maker. a Lane 1-2
indicate the transgenic tomato plants with p35S::SlMAPK7-RNAi, lane 3 indicates negative control, lane 4 indicates positive control.
b Lane 1-12 indicate the transgenic tomato plants with p35S:: SlMAPK7, lane 13 indicates negative control, lane 14 indicates
positive control.

Fig S10. Comparison of the amino acid sequences of SlMAPK7 with AtMAPK4 (a) and AtMAPK11 (b). Sequence alignment shows
that they share high sequence similarity (79% and 78.5%, respectively).
