The plant hormone auxin affects many aspects of root development, including lateral root branching. A high-throughput screen in Arabidopsis thaliana has led to the identification of naxillin, a non-auxin chemical probe that enhances lateral root branching and has revealed an important role of the root cap in regulating this process.
