“…Three typical physiological indicators, Pro, SS, and MDA were determined to evaluate the drought tolerance of weeping forsythia. Pro and SS are important osmoregulation substance, their content in plants increases obviously under drought stress [ 35 ]. Thus, Pro and SS content in plants is usually used to reflect the resistance in response to drought stress.…”

Background Understanding the genetic mechanisms of local adaptation is an important emerging topic in molecular ecology and evolutionary biology. Results Here, we identify the physiological changes and differential expression of genes among different weeping forsythia populations under drought stress in common garden experiments. Physiological results showed that HBWZ might have higher drought tolerance among four populations. RNA-seq results showed that significant differential expression in the genes responding to the synthesis of flavonoids, aromatic substances, aromatic amino acids, oxidation–reduction process, and transmembrane transport occured among four populations. By further reanalysis of results of previous studies, sequence differentiation was found in the genes related to the synthesis of aromatic substances among different weeping forsythia populations. Conclusions Overall, our study supports the hypothesis that the dual differentiation in gene efficiency and expression increases among populations in response to heterogeneous environments and is an important evolutionary process of local adaptation. Here, we proposed a new working model of local adaptation of weeping forsythia populations under different intensities of drought stress, which provides new insights for understanding the genetic mechanisms of local adaptation for non-model species.
