Mejion201 different accessions of A. thaliana from different geographic origins. These accessions were part of the RegMap. Seeds were obtained by growing the parental generation of all lines used side by side in the same growth chambers under the same conditions. The seeds were surface sterilized in 2.8% hypochlorite for 4 min and washed three times in MonoQ sterile water. They were then stratified for 72 h at 4 °C in water and darkness and put to grow on our custom Confocal Chamber System (CCs). The seeds were grown for 3 d in vertically oriented CCs containing 1× Murashige and Skoog (MS) salt mixture, 1% (wt/vol) sucrose and 0.8% (wt/vol) agar. To provide a sterile environment for the CCs and prevent them from drying out, we embedded the CCs into conventional agar plates 2Aug/13/2016
Flowering time in simulated seasonsTwo independent experiments were conducted in this study. Experiment 1 was done with a mapping population of 360 accessions (33), and Experiment 2 used a set of 473 accessions. Each accession in each experiment had four replicates under each of the four growth conditions (two planting seasons by two locations). Both experiments were conducted in two walk-in growth chambers (AR-916, Percival Scientific) that were programmed to cycle the local climates every 5 min from the simulated weather files. The simulated climates were generated by using SolarCalc (35) with sunrise and sunset, light spectrum, temperature, and relative humidity programmed to cycle throughout the day and the season according to 1975?2000 averages (Fig. S5). One chamber was simulating Spain (latitude 41.72091, longitude 2.957075) starting from March 1, and the other chamber was simulating Sweden (latitude 55.71226, longitude 13.207352) starting from May 1st on the first day when plants were put into the chambers.34Aug/13/2016
