A comprehensive phylogenetic backbone of the apple tribe Maleae, including 563 plastomes across 370 species and 26 genera, estimated by IQ-TREE2 based on the whole plastome dataset. Each of the 26 genera is represented by a unique color for clear distinction. Owing to the extensive scope of the tree, it is segmented into four distinct groups (labeled Group A, B, C, and D), each depicted in separate images. The interconnections among these subgroups are denoted by branch connectors labeled α, β, γ, δ, ε, and ζ.
