  abstract = {{R}oot architecture is a crucial part of plant adaptation to soil heterogeneity and is mainly controlled by root branching. {T}he process of root system development can be divided into two successive steps: lateral root initiation and lateral root development/emergence which are controlled by different fluxes of the plant hormone auxin. {W}hile shoot architecture appears to be highly regular, following rules such as the phyllotactic spiral, root architecture appears more chaotic. {W}e used stochastic modeling to extract hidden rules regulating root branching in {A}rabidopsis thaliana. {T}hese rules were used to build an integrative mechanistic model of root ramification based on auxin. {T}his model was experimentally tested using plants with modified rhythm of lateral root initiation or mutants perturbed in auxin transport. {O}ur analysis revealed that lateral root initiation and lateral root development/emergence are interacting with each other to create a global balance between the respective ratio of initiation and emergence. {A} mechanistic model based on auxin fluxes successfully predicted this property and the phenotype alteration of auxin transport mutants or plants with modified rythms of lateral root initiation. {T}his suggests that root branching is controlled by mechanisms of lateral inhibition due to a competition between initiation and development/ emergence for auxin.},
