Effects of HTT2 overexpression on the expression levels of BrpHsf genes. a Expression levels of BrpHsf genes in HTT2–2 seedlings under normal temperature (22 °C). b Expression levels of BrpHsf genes in HTT2–2 seedlings after heat treatment at different temperatures. Error bars represent SD. The relative expression abundance of each gene was measured with three biological replicates. Differences were considered significant (*) if p < 0.05 (Student’s t-test) and highly significant (**) if p < 0.01 (Student’s t-test)
