Abstract

Root development is highly responsive to the availability and distribution of nutrients in the soil. When Arabidopsis roots are exposed to a localised supply of nitrate (NO3- ) the elongation rate of lateral roots in the NO3--rich zone is stimulated 2- to 3- fold. We previously identified a NO3--inducible root-specific gene (ANR1) which encodes a member of the MADS-box family of transcription factors and is essential for the lateral root response to NO3-. In this proposal we aim to elucidate the role of ANR1 in modulating meristematic activity in the lateral root tip by (a) identifying genes that are subordinate to ANR1 in the NO3- response pathway, and (b) determining whether post-translational activation of an engineered version of ANR1, in the absence of NO3- signal, is sufficient to trigger the sequence of events leading to stimulation of LR growth.
