Figure 1 From: Inducible and constitutive heat shock gene expression responds to modification of Hsp70 copy number in Drosophila melanogaster but does not compensate for loss of thermotolerance in Hsp70null flies Variation in larval thermotolerance. The y-axis displays the percentage of third-instar larvae that survived to adulthood after control, pretreatment, heat shock and pretreatment plus heat shock treatments (C, PT, HS and PT+HS respectively on the x-axis). '#Hsp70s (Strain)' indicates Hsp70 copy numbers of the Hsp70 -, Hsp70 A-Ba-, Hsp70 +and Hsp70 traIIIstrains, respectively. Symbols are means ± 1 standard error (SE). For HS and PT+HS treatments, orange symbols indicate heat shocks of 39°C and red symbols indicate heat shocks of 39.5°C. See the methods section for a full description of the treatments.Back to article page
