Transcriptomic responses to drought stress among natural populations provide insights into local adaptation of weeping forsythia.

ABSTRACT:

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
