Research overview:

Since their appearance on earth, plants have naturally evolved mechanisms to thrive in every possible ecosystem. Some of the most interesting cases of plant adaptation have occurred during domestication, where humans strongly selected for characteristics of agricultural interest. Understanding the molecular basis of these adaptive mechanisms is one of the mayor quests in modern biology and the goal of the Adaptive Genomics and Genetics group. We believe that knowledge on the genes and proteins responsible for the variation we observe in the world today will help us breed better crops in the future.

The Adaptive Genomics and Genetics group combines expertise in genomics, genetics and molecular biology and works mainly in two model systems: Arabidopsis thaliana and tomato. Arabidopsis is our model to study natural adaptation, because of its worldwide distribution across many different environments, its small genome, ease of growth and its abundant genetic and genomic resources. Tomato is our model for domestication because its importance as food, its relatively small homozygous genome, and its well-studied domestication history.

Research lines:

Circadian rhythms in agriculture

Our lab showed that domestication delayed circadian rhythms in tomato through selection of knockout alleles of EID1 and LNK2, two light signaling genes (Figure 1). Our working hypothesis is that this modification of light signaling and circadian rhythms represent an advantage for tomato under the long days it encountered when it moved out of its equatorial origin. Our lab works now towards demonstrating this hypothesis and towards characterizing the relationship between light signaling, circadian rhythms and plant performance.

Figure 1. Domestication delayed circadian rhythms in tomato. A) Mean relative position of cotyledon tip over time under constant light of 34 cultivated tomato accessions (red) and 44 S. pimpinellifolium accessions (yellow). Colored shading shows SEM; hatched areas in the background indicate subjective nights. Data from 8 independent experiments. B) Mean circadian period and phase estimates ± SEM (n = 2-5) of the genotypes shown in A). C) Genome-wide logarithm of the odds (LOD) scores from a QTL analysis on leaf movements for phase (red ) and period (black) in a S. pimpinellifolium x S. lycopersicum RIL population. The dashed horizontal line indicates the 5 % significance threshold. D) Mean period (left) and phase (right) estimates ± SEM of transgenic lines carrying wild (yellow) or cultivated (red) alleles of LNK2 (left) and EID1 (right). Stars indicate significant differences (one-way ANOVA and post-hoc Tukey’s HSD test, p < 0.01). E) Gene model representations for EID1 and LNK2 indicating the mutations found in cultivated tomato. F) frequency of mutations in EID1 and LNK2 shown in E) among accessions representing several domestication steps from left to right. Number of accessions of each group is indicated on the x axis.

Genomics of tomato domestication

Large sets of genomic resources such as resequencing, metabolomics and transcriptomics for cultivated and wild tomato accessions have been made publicly available in the last years (Figure 2). Our lab is using these datasets to investigate the effects of domestication and breeding in the genome of this crop. For example, we collaborate with other groups to study the evolution of transposable elements along tomato domestication or the effect of wild introgressions in the genome of cultivated tomato.

Color in each accession is determined by its passport data (gold color for accessions of unknown origin). Outside circles were drawn to delimit sensible phylogenetic groups.

Arabidopsis natural variation

We have been exploring natural variation in metabolite content and gene expression in Arabidopsis thaliana. This is allowing us to find genes and mutations that change the chemical composition or the regulatory networks of plants adapted to different environments. The figure below shows QTL peaks for 22 metabolites that show variation in a Col x Cvi recombinant inbred line population.

Figure 3. Metabolite QTLs in Arabidopsis. Heatmap of logarithm of the odds (LOD) scores scores from QTL analysis on 22 metabolites that present variation in a Col-0 x Cvi recombinant inbred line population. Plants were grown in two independent experiments in 4 different conditions (represented by colored circles on the y axis). Black lines indicate the highest LOD score for each metabolite and condition.
