Wenjie Yan, Baosheng Wang, Emily Chan, Thomas Mitchell‐Olds

New Phytologist > 230 > 3 > 1214 - 1227

The genetic basis of flowering time changes across environments, and pleiotropy may limit adaptive evolution of populations in response to local conditions. However, little information is known about how genetic architecture changes among environments. We used genome‐wide association studies (GWAS) in Boechera stricta (Graham) Al‐Shehbaz, a relative of Arabidopsis, to examine flowering variation...
