Origins and Evolution of WUSCHEL-Related Homeobox Protein Family in Plant Kingdom

<table>A proposed model of the evolutionary history of plant WOX family. The schematic tree represents the proposed evolutionary history of WOX family. Different color represents different clade. The WOX family might originate from green algae and expand in Lycopodiophyta with the appearance of the intermediate clade, and along with the emergence of seed plants, the WOX family generated WUS clade from the intermediate clade. Bry: Bryophyta, Lyc: Lycopodiophyta, Gym: Gymnosperm, Mon: Monocots, Eud: Eudicots, Ppa: <i>Physcomitrella patens</i>, Smo: <i>Selaginella moellendorffii</i>, Pta: <i>Pinus taeda</i>, Osa: <i>Oryza sativa</i>, and Ath: <i>Arabidopsis thaliana</i>.</table>
