Auxin transport routes in plant development (2009, background): “Auxin flow is redirected towards the lower side of the root tip, from where it is transported through the lateral root cap and epidermal cells towards the elongation zone, where growth-inhibitory auxin responses are induced (Swarup et al., 2005).”

Intracellular trafficking and proteolysis of the Arabidopsis auxin-efflux facilitator PIN2 are involved in root gravitropism (2006, background): “However, the apparent restoration of eir1–4 root gravitropism by 35S:PIN2–GFP expression indicates that this ectopic PIN2 accumulation did not interfere with root bending, and further confirms the importance of lateral root-cap and epidermis cells for root gravitropis”

Growth activity, rooting capacity, and tropism: three auxinic precepts fulfilled by melatonin (2017, background): “Of the four AUX/LAX genes known, melatonin treatment in Arabidopsis severely down-regulated AUX1, which is involved in the regulation of lateral root development, root gravitropism, root hair development, and leaf phyllotaxy (Swarup et al. 2005).”
Identifying traits to improve the nitrogen economy of wheat: Recent advances and future prospects (2009, background): “…should aim to evaluate the use of marker-assisted backcrossing for root QTLs, and exploit findings in Arabidopsis where root screens for mutants have identified genes such as AUX1 and LAX3 that regulate important root architectural traits such as lateral root development (Swarup et al., 2005).”
Auxin: the looping star in plant development. (2008, background): “Membrane-associated AUX1 expression in root cap and root epidermis cells further links the agravitropic root phenotype of aux1 to defects in polar auxin transport (113).”
Root System Architecture from Coupling Cell Shape to Auxin Transport (2008, neutral): “These values have served as reference for parameter choices used in other modeling studies [5–7] (leading to ~10 times lower PIN-mediated permeability value than our default values used here).”
Different plant hormones regulate similar processes through largely nonoverlapping transcriptional responses. (2006, background): “Changes in hormone levels may also be a highly localized effect (e.g., Swarup et al., 2005).”
