LACs and PRXs localize to nonlignifying cell types in the inflorescence stem of Arabidopsis. Representative images depicting the tagged LAC or PRX under its native promoter (red), brightfield, and merged image are shown. Arrows indicate trichomes and arrowheads indicate epidermal cells. F, Fiber; Ph, phloem; V, xylem vessel element; xp, xylem parenchyma. A and B, AtLAC10-mCherry localizes to trichomes (A) and cell corners of epidermal cells (B). C and D, AtPRX42-mCherry localizes to the cell corners of nonlignifying xylem parenchyma cells (C) and the primary cell wall of phloem cells (D). E, AtPRX52-mCherry localizes to the primary cell wall of trichomes. F, AtPRX71-mCherry localizes to the cell corners of epidermal cells. Scale bars = 50 µm (A and E) and 20 µm (B–D and F).
