Fig. 7From: Genome-wide identification and analysis of the SUPPRESSOR of MAX2 1-LIKE gene family and its interaction with DWARF14 in poplarExpression patterns of PtSMXL gene under treatment with different GR24 concentrations. Whole seedling stems were used as the experimental material. Sampling at 30 days after processing with 0, 2, 5, 10, 15, and 20 μM GR24, and the relative expression level of the sample treated with 0 μM GR24 was set to 1. Asterisks indicate statistically significant differences between 0 μM control group and other groups (* P ≤ 0.05, ** P ≤ 0.01)Back to article page
