From: Small GTP-binding protein PdRanBP regulates vascular tissue development in poplar
Overexpression of PdRanBP stunted growth and induced sylleptic branches; PdRanBP downregulation produced taller plants with thicker stems. a, b qRT-PCR analysis confirming PdRanBP overexpression in the transgenic poplar lines G9 and G15. TUA1 (a) and UBQ1 (b) were used as control genes. The error bars represent the standard error (SE) of three replicates. WT: wild poplar; G9, G10 and G15: transgenic poplar lines overexpressing PdRanBP (OE); GA106, GA515, GA516 and GA521: transgenic poplar lines in which PdRanBP is downregulated (DR). The asterisks indicate significant differences between the transgenic lines and WT (*P < 0.05). c Phenotypic comparison of 120-day-old WT poplar (left) and the PdRanBP-OE line G15 (right). d Phenotypic comparison of 120-day-old WT plants (left) and the PdRanBP-DR line GA106 (right). The scale bars correspond to 20.76 cm in B, and 23.8 cm in C
