Abstract excerpt
Localized proliferation of lateral roots in NO(3)(-)-rich patches is a striking example of the nutrient-induced plasticity of root development. In Arabidopsis, NO(3)(-) stimulation of lateral root elongation is apparently under the control of a NO(3)(-)-signaling pathway involving the ANR1 transcription factor. ANR1 is thought to transduce the NO(3)(-) signal internally, but the upstream NO(3)(-) sensing system...
