WebApr 11, 2008 · Abstract. The root hair is a model system for understanding plant cell tip growth. As phosphatidylinositol 3-phosphate [PtdIns(3)P] has been shown in other plant cell types to regulate factors that affect root hair growth, including reactive oxygen species (ROS) levels, cytoskeleton, and endosomal movement, we hypothesized that PtdIns(3)P is … WebSN - 1664-462X Their expansion is limited to the root hair apex, where growth is reported to take place in a pulsating manner. These growth pulses coincide with oscillations of the apoplastic and cytosolic pH in a similar way as has been reported for pollen tubes. WebIn Arabidopsis, root hairs initiate at the basal (distal) end of trichoblast cells and elongate along the radial axis by polar tip growth, pointing toward the distal end of the root (see Figure 6 ).
