The evolution analysis of PbrLBD gene family. (a) Distribution and synteny of PbrLBD gene family in pear genome. The circle picture was plotted by the Circos software (version 0.69.2). The red points mark the position distribution of LBD gene on 17 pear chromosomes. The red lines show the collinear gene pairs of LBD gene family. (b) Segmental duplication between members of PbrLBD family. (A) PbrLBD11 (Pbr029040.1) and PbrLBD15 (Pbr033910.1), (B) PbrLBD1 (Pbr033910.1) and PbrLBD2 (Pbr022066.1), (C) PbrLBD50 (Pbr019737.1) and PbrLBD30 (Pbr021980.1), (D) PbrLBD36 (Pbr016186.1) and PbrLBD23 (Pbr000434.1), (E) PbrLBD5 (Pbr009548.1) and PbrLBD25 (Pbr010928.1), (F) PbrLBD44 (Pbr007737.1) and PbrLBD45 (Pbr016876.1). The figure shows a region of 100 kb on each side flanking the PbrLBD genes. Duplicated gene pairs are connected with bands. Chromosome segments are indicated by black horizontal lines, and a broad line with arrowhead represents a gene and its transcriptional orientation. Text indicates the gene ID. The PbrLBD genes are shown in red, duplicated genes and other genes are shown in green; and homologous genes are linked by the red line. (c) The distribution of mean Ks and 4DTv value of 22 PbrLBD duplicated gene pairs. In the left figure, the x-axis shows the mean Ks value, and the y-axis shows the number of gene pairs. In the right, the x-axis shows the 4DTv value, and the y-axis shows the number of gene pairs. The data were plotted using the hist function in R
