To obtain sequences of WOX family in plant kingdom, we used the full-length sequence of AtWUS (At2g17950) [7] as a TBLASTN query against the available genome sequences (see Supplementary Table 1 in Supplementary Materials available online at including the unicellular green algae (3 species), the bryophyte (1 species), the Lycopodiophyta (1 species), the Gnetophyta (1 species), the coniferophyta (4 species), the Ginkgophyta (1 species), and flowering plants (39 species).
Among the living gymnosperms, four phyla could be considered: Cycadophyta (cycads), Ginkgophyta (Ginkgo biloba L.), Coniferophyta (conifers), and Gnetophyta (gnetophytes) [1].
Las Eudicots representan el 78% de los taxones con 313 especies, las Monocots el 16%, las Gnetophyta representadas por dos especies (0,5%) y los Pteridofitos con 23 especies (5,8%) (Tabla 2).
