  abstract = {{R}oot architecture plays an important role in water and nutrient acquisition and in the ability of the plant to adapt to the soil. {L}ateral root development is the main determinant of the shape of the root system and is controlled by external factors such as nutrient concentration. {H}ere it is shown that lateral root initiation and root gravitropism, two processes that are regulated by auxin, are co-regulated in {A}rabidopsis. {A} mathematical model was generated that can predict the effects of gravistimulations on lateral root initiation density and suggests that lateral root initiation is controlled by an inhibitory fields mechanism. {M}oreover, gene transactivation experiments suggest a mechanism involving a single auxin transport route for both responses. {F}inally, co-regulation may offer a selective advantage by optimizing soil exploration as supported by a simple quantitative analysis.},
