What can cold‐induced transcriptomes of Arctic Brassicaceae tell us about the evolution of cold tolerance?
Abstract Little is known about the evolution of cold tolerance in polar plant species and how they differ from temperate relatives. To gain insight into their biology and the evolution of cold tolerance, we compared the molecular basis of cold response in three Arctic Brassicaceae species. We conduc...
