Genotype-environment interactions may be a potent force maintaining genetic variation in quantitative traits in natural populations. This is shown by a simple model of additive polygenic inheritance in which the additive contributions of alleles vary with the environment. Under simplifying symmetry assumptions, the model implies that the variance of the phenotypes produced across environments b...

In the natural world, genotype expression is influenced by an organism's environment. Identifying and understanding the genes underlying phenotypes in different environments is important for making advances in fields ranging from evolution to medicine to agriculture. With the availability of genome-wide genetic-marker datasets, it is possible to look for genes that interact with the environment...

• The strength and consistency of genotypic differences in disease resistance determine the potential for resistance evolution in host populations that rely on vegetative reproduction. Here we surveyed infection intensity of host genotypes across space and time to estimate genotypic and environmental effects on quantitative disease resistance. • Cloned fragments of 12 Euthamia graminifolia geno...

The phenotype of an organism is determined by its genotype and environment. An interaction between these two arises from the differential effect of the environment on gene expression in distinct genotypes; however, the genomic properties identifying these are not well understood. Here we analyze the transcriptomes of five C. elegans strains (genotype) cultivated in five growth conditions (envir...

Wheat is an important winter cereal of Nepal but drought limits its production as 34.44% wheat producing area under non-irrigated environment. The identification high yielding potential varieties with stable performance environment may be the way forward to cope limited productivity. So, in this study, effect genotype by interaction on yield fourteen and two promising lines environmental condit...
