Phylotranscriptomic discordance is best explained by incomplete lineage sorting within Allium subgenus Cyathophora and thus hemiplasy accounts for interspecific trait transition.

ABSTRACT: The transition of traits between genetically related lineages is a fascinating topic that provides clues to understanding the drivers of speciation and diversification. Much can be learned about this process from phylogeny-based trait evolution. However, such inference is often plagued by genome-wide gene-tree discordance (GTD), mostly due to incomplete lineage sorting (ILS) and/or introgressive hybridization, especially when the genes underlying the traits appear discordant. Here, by collecting transcriptomes, whole chloroplast genomes (cpDNA), and population genetic datasets, we used the coalescent model to turn GTD into a source of information for ILS and employed hemiplasy to explain specific cases of apparent "phylogenetic discordance" between different morphological traits and probab
