Dual control: Plant peptide hormone generates distinct cell structures for water flow

Researchers have found that a peptide hormone regulates two different cell division processes that generate centrally important structures for the flow of water through plants. By binding to different receptors, the hormone controls the formation of not only xylem (the vessels that transport water up from the roots), but also stomata (the leaf pores through which water evaporates).
