Gene Expression in whole roots of the Arabidopsis nlp7-1 mutant

ABSTRACT: The root cap surrounds the root meristem, protecting it from harsh environments and facilitating root movement through soil. In Arabidopsis, new root cap cells produced in the meristem displace older cells toward the root periphery, where they undergo programmed cell death and are released from the root. This rapid cell turnover is a unique feature of the root cap and is modulated in part by the combined action of four NAC transcription factors, as well as cell wall modification enzymes. Here we show that the transcription factor NIN-LIKE PROTEIN 7 (NLP7) regulates root cap maturation in Arabidopsis by modulating expression of each of the NAC TFs as well as several cell wall modifying enzymes. NLP7 is a homolog of NIN, a transcription factor required for nodulation in Lotus japonicas, and
