Controlling elemental composition is critical for plant growth and development as well as the
nutrition of humans who utilize plants for food. Uncovering the genetic architecture …

In order to grow on soils that vary widely in chemical composition, plants have evolved
mechanisms for regulating the elemental composition of their tissues to balance the mineral …

Background Understanding the relationship between environment and genetics requires the
integration of knowledge on the demographic behavior of natural populations. However, the …

We resequenced 876 short fragments in a sample of 96 individuals of Arabidopsis thaliana
that included stock center accessions as well as a hierarchical sample from natural …

The concentrations of mineral nutrients in seeds are critical to both the life cycle of plants as
well as human nutrition. These concentrations are strongly influenced by soil conditions, as …

Soil is a heterogeneous reservoir of essential elements needed for plant growth and
development. Plants have evolved mechanisms to balance their nutritional needs based on …

The accumulation of a given element is a complex process controlled by a network of gene
products critical for uptake, binding, transportation, and sequestration. Many of these genes …

Background The model plant Arabidopsis thaliana (Arabidopsis) shows a wide range of
genetic and trait variation among wild accessions. Because of its unparalleled biological …

The genomic revolution is having a tremendous impact on the study of natural variation. It is
making it possible finally to discover the molecular basis of complex traits, a fundamental …

The importance of genetic drift in shaping patterns of adaptive genetic variation in nature is
poorly known. Genetic drift should drive partially recessive deleterious mutations to high …
