Fig. 4From: Genome-wide characterization, evolution, and expression analysis of the leucine-rich repeat receptor-like protein kinase (LRR-RLK) gene family in Rosaceae genomesThe circos figure for chromosome locations with segmental duplication links. a Arabidopsis thaliana, b Fragaria vesca, c Malus domestica, d Pyrus bretschneideri, e Prunus mume, f Prunus persica. The blue lines indicate segmented duplicated gene pairs that were traced to the paleohexaploidization event (~140 million years ago). The yellow lines indicate segmented duplicated gene pairs that were tranced to recent duplication event (30~45 million years ago)Back to article page
