Characteristics of SlSRM1-like gene expression. A Expression of the SlSRM1-like gene in different tissues of tomato plants. Except for the fruits, all the tissues were collected from tomato plants at 45 d after sowing. DAP, days after pollination. Green fruit refers to the fruit before color change. The expression level in each tissue was based on the expression in the roots. B Expression changes of the SlSRM1-like gene over time after treatment with auxin. Thirty-day-old tomato plants were sprayed with 50 μmol/L IAA solution, and plants sprayed with distilled water were used as controls
