Fig. 2: Phylogenetic tree of CsKPI genes in tea plant.

Nineteen KPI proteins from ten plant species were used to construct an unrooted neighbor joining phylogenetic tree. The bootstrap values of the confidence levels are shown as percentages at branch nodes. The CsKPI genes are highlighted in purple. The red half-frame indicates a tandem duplication event between the two framed genes. The solid blue circles indicate tandem duplications of genes from other plant species
