摘要
Plants are often exposed to drought stress, and decreases in the soil water content can prevent plants from reaching their full genetic potential. Populus davidiana Dode belongs to the genus Populus, and it is a temperate deciduous tree that is cold and drought tolerant. To investigate the mechanism of P. davidiana response to drought stress, transcriptome analysis was performed on drought and control treatments of P. davidiana. We identified 10230 differentially expressed genes (DEGs). Most DEGs were enriched in pathways related to transcriptional regulation and hormone signal transduction, ROS metabolism, lignin synthesis, and the sugar metabolism process in two contrasting groups. Compared with the control condition, soluble sugars, proline, and POD activity were all increased under drought stress. In addition, Na+, K+, and Ca2+ were all higher under drought stress than in the control. These results not only revealed the mechanism of tolerance to drought stress in P. davidiana, but also promoted the development and application of drought-tolerant genetic resources in P. davidiana.
