Definitions

1. A tree data structure whose internal nodes represent the concatenation of their child branches.
2. A phylogenetic tree constructed from concatenated alignments.

Examples

“When working on the tree representations in our algorithms, we assume that the symbol [.] (vₗ, vᵣ) means a concatenation tree with root "." and children vₗ and vᵣ.”

“While galleys are sent between the several objects in a concatenation tree, galleys arriving at the left-most leaf are not expanded, while all other galleys are expanded as far as possible (are “forced”) on arrival.”

“Martin and colleagues recently reported a lack of correspondence between individual protein trees and the concatenation tree in several datasets of archaeal and bacterial proteins (Thiergart et al., 2014).”

“For example, in the analyses of the full CDS data, the coalescent tree supports a Neohymenopogon + Mouretia clade (Supplementary Figure 1), and the concatenation tree was inconclusive (i.e., support values were below 95%) for several relationships (Supplementary Figure 2) and inconsistent with the coalescent tree.”

“Similarly, in the genome sequency analysis of C. salicifolius, Lv et al. (2020) constructed an amino acid sequence-based concatenation tree of 103 single-copy gene sets and coalescent tree of 1,420 low-copy gene sets from 17 species, all of which support that magnoliids are sister plants to eudicots.”
