Cover Story: Pollen tube tip growth requires timely and location specific coordination of exocytosis and enzyme activity - inside the cell membrane, and outside in the cell wall. Using transient growth inhibition, we show that a gradient in protons, manifest as an alkaline band just behind the tube tip, disappears as growth stops, and is re-established well before growth resumes. A tip-focused calcium ions gradient also reforms, but co-incident with resumed growth. Thus, a proton gradient precedes and may direct growth, while the calcium gradient follows growth, marking the region of greatest expansion. View the paper
