Inputs for the diurnal and annual needle transcriptome study. a Douglas-fir branches, showing the location of sampled needles (red arrow). b Annual environmental conditions and growth rhythm for trees used in this experiment. Shown are: upper panel, light conditions with photoperiod (bar chart) and radiant exposure (blue line); middle panel, weather conditions with precipitation (bar chart) and temperature (high = red line; low = blue line); lower panel, growth rhythm with terminal shoot growth (bar chart) and radial growth (blue line). Annual needle sample times are identified in the lower panel using black triangles. The date of the diurnal study is identified as a grey triangle
