|Pb Mine soil||Arabidopsis thaliana (360 accessions) were cultivated in two soil types with contrasted Pb concentration placed in a growth chamber. Germination and survival were monitored and rosette diameter (RD) of 3 individuals per accession and soil type was measured weekly for 4 weeks. Growth rate of each accession was calculated as mean(RDMine) / mean(RD Control) of the last RD measure. Fifty-day old plants were harvested to measure its nutrient mineral contents.||15||Aug/06/2021|

|Salt induced changes in Root System Architecture||Salt stress affects not only plant size, but also plant architecture. In this study, we focused on salt stress-induced changes to Root System Architecture, by germinating the seedlings on vertical agar growth medium (no salt) and transplanting 4 days old seedlings into plates containing 0, 75 and 125 mM NaCl. The Root System Architecture phenotypes were quantified using EZ-Rhizo software for at least 4 replicates per accession per condition. The plants grown under control conditions were measured 4 days after transfer (8 days after germination), while plants growing at both salt stress conditions were measured 8 days after transfer (12 days after germination). The Root System Architecture traits include Main Root Length, Total Root Size, Lateral Root Length and ~ Density, as well as the length of individual zones (basal, branching, apical) on the main root.

|Lifetime fitness in Germany and Spain under rainfall manipulation||Data from Exposito-Alonso et al. (2019). A map of climate change-driven natural selection in Arabidopsis thaliana. Nature.
The data is comprised of three fitness traits in eight experimental environments and 98 climate variables of origin.
Fitness traits include Survival from germination to reproductive adult, the number of Seeds produced per individual adult, and the product of both (Fitness). The traits have already been scaled by the mean of the experimental population, so they are relative fitness traits. The codes of each experiment follow a three letter format. The first position is either "m" from Madrid (Spain), "t" from Tuebingen (Germany). The second position is either "h" from high rainfall or "l" from low rainfall. The third position is either "p" from population replicate pot (where plants are at high density), or "i" from an individual replicate pot (where there was one plant per pot). In combination, for example, the code "mlp" refers to the fitness in the experiment of Madrid, at low precipitation, and high plant population density in the plot.
Climate variables were used to understand the relationship between genome variation and environment of origin. They were derived intersecting the geographic coordinates where natural lines were originally collected and climate maps from worldclim.org (and derived metrics).||122||Jun/27/2019|

|Satbhai et. al. Nature Communications 2017||Low availability of Fe significantly limits crop yields in many parts of the world. However, it is largely unknown which genes and alleles adjust plant growth in Fe limited environments. Using natural variation of a geographically restricted panel of Arabidopsis thaliana accessions, we identify allelic variation at the FRO2 locus associated with root length under iron deficiency. We show that non-coding sequence variation at the FRO2 locus leads to variation of FRO2 transcript levels, as well as ferric chelate reductase activity, and is causal for a portion of the observed root length variation. These FRO2 allele dependent differences are coupled with altered seedling phenotypes grown on iron-limited soil. Overall, we show that these natural genetic variants of FRO2 tune its expression. These variants might be useful for improvement of agronomically relevant species under specific environmental conditions, such as in podzols or calcareous soils (Reference: doi:10.1038/ncomms15603).||5||Sep/05/2017|
