Increasing temperature affects transcript abundance by active promotion of transcription rates. (A) Histogram to show the Q₁₀ of decay rates at 17°C for all 7,291 genes analyzed; the mean Q₁₀ for decay rate is 3.29 and the median 2.81. (B) Histogram to show the Q₁₀ of transcription rates at 17°C for all 7,291 genes analyzed; the mean Q₁₀ for transcription rate is 3.57 and the median 3.40. A number greater than 1 indicates higher transcription/decay rates at 27°C than at 17°C. (C) Scatter plot showing the Q₁₀ of transcription rate plotted against Q₁₀ of decay rate for genes whose transcript abundances are at least 1.5-fold increased (red), 1.5 fold-decreased (blue) or unchanged (black) with increasing temperature. (D) Box plot to show the Q₁₀ of decay rates for genes with transcript abundances that are higher, lower or unchanged at 27°C compared to 17°C. Boxes show the median and the 5th, 25th, 75th and 95th per percentiles for each group of Q₁₀s. (E) Box plot to show the Q₁₀ of transcription rates for genes with transcript abundances that are higher, lower or unchanged at 27°C compared to 17°C. Boxes show the median and the 5th, 25th, 75th and 95th per percentiles for each group of Q₁₀s.
