WebRoot hair growth is a result of directed swelling of the cell by absorbed water, starting at the basal position of the hair cell (Fig. 2.8 A). Polarity is established by auxin signaling and by the appropriate trafficking of the auxin influx carrier AUXIN RESISTANT 1 (AUX1) into the apical and basal ends of epidermal cells (Grebe et al., 2002; Masucci and Schiefelbein, … WebRoot growth is favoured in the absence of the infra-red absorbed b y the water- filter.
