A computational Evo-Devo approach for elucidating the roles of PLETHORA transcription factors in regulating root development.

ABSTRACT: PLETHORA (PLT) transcription factors play essential roles in regulating various developmental processes in plants, including embryogenesis, rhizotaxis, phyllotaxis, and most prominently, root development, by regulating cell proliferation and differentiation along the root. Despite their important roles in plant development, PLT transcription factors have mainly been studied in Arabidopsis thaliana and only a few crop species. A. thaliana has six PLT genes, which are expressed in overlapping domains and have partially redundant activities, with numerous shared target genes. Here we identified putative PLT orthologs across Viridiplantae, including representatives of all extant plant clades, reconstructing the molecular phylogeny of PLTs and integrating synteny and microsynteny analyses.
