Fig. 1. Temperature responses of plant-associated fungi (blue) and oomycetes (red) life history processes.
a Minimum temperature (Tmin), b optimum temperature (Topt), c maximum temperature (Tmax), d temperature range (Tmax–Tmin). e Skew, where values >0.5 indicate the Topt is closer to Tmax than Tmin. The grey line indicates where Topt lies half-way between Tmin and Tmax. Processes are disease development (DD), fruitification (FR), growth in culture (GC), infection (IN), spore germination (SG), and sporulation (SP). a–e Boxplot boundaries reflect the inter-quartile range, the horizontal bar is the median. Summary statistics including sample sizes are reported in Supplementary Table 1. f Illustration of skew for a temperature response function. The black points show cardinal temperatures, with midpoint between Tmin and Tmax in grey. Unskewed response in grey, skewed response in black.
