Fig. 2

The effect of exogenous BL on the dwarfing phenotype of dwarf-type pears and the expression of PcDWF1 in different tissues of the dwarf-type (DW) and standard-type (WT) pears. a The phenotype of the dwarf-type pear plants after spraying with exogenous BL for 1 month, with the dwarf-type and standard-type pears as the control. The plant height (b) and internode length (c) of the dwarf-type pears after spraying with exogenous BL for 1 month, with the dwarf-type and standard-type pears as the control. d The phylogenetic tree was constructed using MEGA5.2 software with the neighbor-joining method and a bootstrap test with 1000 iterations based on the amino acid sequences of BR biosynthetic rate-limiting genes in pear and Arabidopsis. e The expression of PcDWF1 in the leaves, stems, and roots of dwarf-type and standard-type pears. Data are the means ± SD of triplicate experiments. Different lowercase letters indicate significant differences according to Fisher’s LSD (P < 0.05). Asterisks (*) indicate significant differences from the control (Student’s t-test, *P < 0.05, **P < 0.01)
