Effects of environmental factors on PUT expression. X-Y plots show soil water availability (a) temperature (b) and day length (c) during the course of the year. The corresponding bar plots show the values of the respective regressors TAW, TEMPERATURE and DAYLENGTH that were used in the linear models. Red and blue lines indicate the sampling time point in the common gardens in Wiesloch and Schluchsee, respectively. Curves were smoothed using loess transformation. Temperature shown in the bar plot (b) was centered to a 4 week running average while day length (c) was centered to the maximum day length of the year. Day length in May was transformed to positive values to mimic the directed developmental processes occurring during a growing period. d Standardized expression of PUTs that are significantly responding to TAW, TEMPERATURE or DAYLENGTH in Salmon Arm (magenta) and Cameron Lake (cyan) relative to the environmental parameters
