The T3WOX/modern Selaginella kraussiana WOX11C is expressed in lycophyte vascular bundles. a In situ of SkWOX11C in the shoot apex. b In situ of SkWOX11C on cross section of vascular bundle in stem tissues. c Expression of SkWOX11B in the shoot apex. d In situ of SkWOX11B on cross section of stem. e Abbreviated land plant phylogeny, and (f) Revised trajectory of WOX gene function in land plants (adapted from [18]). Pink and green arrows indicate shoot apical meristem and emerging leaf primordia, respectively. Yellow arrows indicate phloem. Scale bars = 0.05 mm
