Genotype×environment interaction QTL mapping in plants: lessons from Arabidopsis

Trends Plant Sci. 2014 Jun;19(6):390-8. doi: 10.1016/j.tplants.2014.01.001. Epub 2014 Jan 31.


Plant growth and development are influenced by the genetic composition of the plant (G), the environment (E), and the interaction between them (G×E). To produce suitable genotypes for multiple environments, G×E should be accounted for and assessed in plant-breeding programs. Here, we review the genetic basis of G×E and its consequence for quantitative trait loci (QTL) mapping in biparental and genome-wide association (GWA) mapping populations. We also consider the implications of G×E for understanding plant fitness trade-offs and evolutionary ecology.

Keywords: QTL × environment interaction; antagonistic pleiotropy; genotype × environment interaction; phenotypic plasticity.
