Phylogenomic analysis of the APETALA2 transcription factor subfamily across angiosperms reveals both deep conservation and lineage-specific patterns.

ABSTRACT: The APETALA2 (AP2) subfamily of transcription factors are key regulators of angiosperm root, shoot, flower and embryo development. The broad diversity of anatomical and morphological structures is potentially associated with the genomic dynamics of the AP2 subfamily. However, a comprehensive phylogenomic analysis of the AP2 subfamily across angiosperms is lacking. We combined phylogenetic and synteny analysis of distinct AP2 subclades in the completed genomes of 107 angiosperm species. We identified major changes in copy number variation and genomic context within subclades across lineages, and discuss how these changes may have contributed to the evolution of lineage-specific traits. Multiple AP2 subclades show highly conserved patterns of copy number and synteny across angiosperms, while
