Liriodendron is a genus of Magnoliaceae， which consists of two relict species， Liriodendron chinense and L. tulipifera. Although the morphologies are highly similar， the two species exhibit different adaptive capacity. Dehydrins (DHNs) are abiotic stresses resistant proteins in planta， which are associated with adaptive evolution. To better understand the evolution divergence between L. chinense and L. tulipifera and how DHN genes are associated with adaptation evolution， we firstly investigated the DNA polymorphisms of the LcDHN-like gene in 21 L. chinense and 6 L. tulipifera populations.
