Expression profile of hmhsp70 under heat stress. Mycelia of H. marmoreus were treated at 42 °C for 0, 0.5, 1, 2, 3 and 4 h. The 18S rRNA gene was used as an internal control. Each value is the mean from three parallel replicates ± SD. One-tailed t test, performed by SPSS 18.0 (Chicago, Illinois), was used to calculate statistical significance. Different letters indicate a significant difference at P < 0.05
