Root hair-forming cells develop root hairs as tubular protrusions from their outer membrane, where hairs are uniformly initiated towards, albeit not completely at, the root tip-oriented (basal) ends of cells (Masucci and Schiefelbein, 1994).
Antibodies against Vglut3 label the basal end of hair cells and labeling is not present in asteroid/vglut3 mutants.
In Arabidopsis the polar initiation site is located towards the basal end of epidermal cells.
In wild-type roots, hairs normally initiate and emerge towards the basal end of trichoblast cells [ 6, 7, 23].
…depending on the type of hair cell, either end on the basal end of the cell or form a calyx, or cuplike structure, that surrounds it.
They pierce the basement membrane and, depending on the type of hair cell, either end on the basal end of the cell or form a calyx, or cuplike structure, that surrounds it.
The influx of calcium triggers neurotransmitter release from the basal end of the cell into the auditory nerve endings and fires the fiber.
In many plant species each RH cell has a single hair placed close to the basal end of the cell (end nearest the root tip) [6], [7], an arrangement that leads to regular spacing of root hairs, and is thought to help maximise nutrient uptake [8].
In a wildtype root hair cell the ROPs become localised in a patch positioned towards the basal end of the cell (Figure 1B).
The wildtype ROP localisation becomes possible when the auxin gradient is such that at the basal end of the cell the parameter values fall deeper within the Turing space than at the apical end.
