Whether phenotypic mean values and plasticity share similar genetic architectures remains elusive. A study examining multiple traits in a maize NAM population using GWAS showed that genes underlying mean and plasticity measures form distinct groups.
The genetic architecture underlying rapid phenotypic changes remains largely unknown. Here, the authors show that genes with an intermediate degree of pleiotropy have the highest rate of adaptive evolution in Arabidopsis thaliana.
