Creep rate of frozen–thawed arabidopsis hypocotyls. The creep rate of frozen–thawed wild type (WT) and 35S::AtEXLA2 6_2 (OEX 6_2) hypocotyls was measured under four different loads at pH 5 and pH 6 without heat inactivation, and pH 5 after heat inactivation (inact.) (mean ± s.e., n = 8–9). Asterisks indicate significant differences between the over-expression line and the WT under the same load and pH value. In all cases, the creep rate at pH 5 was significantly higher than that at pH 6 and pH 5 after heat inactivation (not shown on the plot).
