Parsimonious Model of Vascular Patterning Links Transverse Hormone Fluxes to Lateral Root Initiation: Auxin Leads the Way, while Cytokinin Levels Out
Fig 10
An auxin circuit is generated in the stele by polar localisation of PIN1.
(A, B) A heatmap of the auxin flux in the stele of plants with polar (A) and apolar (B) PIN1 localisation with arrows depicting the overall flux pattern. The schematic models in the lower panels only show PIN1 localisation, since PIN3, PIN7, and the auxin importer are apolarly localised, as in all other simulations.
