| DAAR | GWAS of three mass features of N-malonyl-D-allo-isoleucine in Arabidopsis thaliana inbred lines using ~250k SNPs in 416 accessions | 3 | Sep/05/2017 |
| Ion Concentration | Plants were grown in a controlled environment with 10 h light/
14 h dark (90 mmol m22s21 photosynthetically active light) and 19
to 22uC, as previously described [31]. Briefly, seeds were sown
onto moist soil (Promix; Premier Horticulture) in 10.506210 20 row
trays with various elements added to the soil at subtoxic
concentrations (As, Cd, Co, Li, Ni, Rb, and Se [31]) and the
tray placed at 4uC for 3 days to stratify the seeds and help
synchronize germination. Each tray contained 108 plants, six
plants each from 18 accessions, with three plants of each accession
planted in two different parts of the tray. Each tray contained four
common accessions (Col-0, Cvi-0, Fab-2 and Ts-1) used as
controls, and 14 test accessions. Trays were bottom-watered twice
per week with 0.25-strength Hoagland solution in which Fe was
replaced with 10 mM Fe-HBED[N,N9-di(2-hydroxybenzyl)ethyle-
nediamine-N,N9-diacetic acid monohydrochloride hydrate; Strem
Chemicals, Inc.). After 5 weeks plants were non-destructively
sampled by removing one or two leaves and the elemental
composition of the tissue analyzed by Inductively Couple Plasma
Mass Spectroscopy (ICP-MS). The plant material was rinsed with
18 MV water and placed into Pyrex digestion tubes. | 19 | Mar/21/2017 |

| Mejion | 201 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 | 2 | Aug/13/2016 |
| Flowering time in simulated seasons | Two 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. | 34 | Aug/13/2016 |
