|a The BRI1 EMS SUPPRESSOR 1/BRASSINAZOLE RESISTANT 1 (BES1/BZR1) plays a vital role in plant growth and development and stress responses, but there are few studies on poplar BES1 genes. In this study, we identified 14 BES1 genes in the Populus trichocarpa genome and analyzed the expression under hormone treatment and abiotic stress. The PtrBES1 genes were classified into seven subgroups (I-VII) through phylogenetic analysis. All the paralogous gene pairs were shown to be subjected to expansion by segment duplication and purification selection during the PtrBES1 family evolution. Promoter cis-element analysis showed that the PtrBES1 promoter contains stress related cis-elements including ABRE-motif, MBS and TC-rich elements. Quantitative real time reverse transcription PCR (RT-qPCR) analysis showed that the PtrBES1 genes were upregulated upon NaCl, Polyethylene glycol 6000 (PEG6000) stress as well as the major stress hormone abscisic acid (ABA) treatment. Under the three treatments, PtrBES1-7 showed high expression levels in leaves and roots. Physiological experiments showed that the overexpression PtrBES1-7 line could enhance tolerance to drought stress in P. trichocarpa by improving the ability to scavenge ROS (reactive oxygen species). This is specifically reflected in the fact that the overexpression line contains less ROS (O2- and H2O2) and more antioxidant enzymes (1.42 times SOD and 1.5 times POD) than the control line. The preliminary results of this study provided a solid basis for the future functional studies of the BES1 gene family in P. trichocarpa
