Excision frequency for CemaT1 transposons at three loci (F26H9, W04G5, Y51A2D) for two strains of C. elegans (N2, AB2) in response to five different conditions of environmental stress, plus no stress controls. Excision frequency given as the proportion of excision footprints to the number of nonexcised transposons at a given locus. Bars show proportions of excision for Low- and High-oxidative stress, Low (35 °C for 1 h), Serial (five serial exposures of 35 °C for 1 h, 30 min at 20 °C) and High (39 °C for 2 h) heat exposures, and No Stress controls.
