Background  Previous research has demonstrated that ectopic expression of Ran-binding protein (RanBP) in  Arabidopsis  results in more axillary buds and reduced apical dominance compared to WT plants. However, the function of  RanBP  in poplar, which has very typical secondary growth, remains unclear. Here, the  Populus deltoides  (Marsh.)  RanBP  gene ( PdRanBP ) was isolated and functionally characterized by ectopic expression in a hybrid poplar ( P. davidiana  Dode ×  P. bolleana  Lauche).    Results   PdRanBP  was predominantly expressed in leaf buds and tissues undergoing secondary wall expansion, including immature xylem and immature phloem in the stem. Overexpression of  PdRanBP  in poplar increased the number of sylleptic branches and the proportion of cells in the G2 phase of the cell cycle, retarded plant growth, consistently decreased the size of the secondary xylem and secondary phloem zones, and reduced the expression levels of cell wall biosynthesis genes. The downregulation of  PdRanBP  facilitated secondary wall expansion and increased stem height, the sizes of the xylem and phloem zones, and the expression levels of cell wall biosynthesis genes.    Conclusions  These results suggest that  PdRanBP  influences the apical and radial growth of poplar trees and that  PdRanBP  may regulate cell division during cell cycle progression. Taken together, our results demonstrated that PdRanBP is a nuclear, vascular tissue development-associated protein in  P. deltoides .
