Abstract:
Plant roots are essential for nutrient and water uptake and play a crucial role in plant growth and development. The development of roots is a complex process regulated by numerous factors, among which transcription factors (TFs) like WUSCHEL-related homeobox (WOX) have an essential function. The importance of WOXs in root development cannot be overstated. They act as key regulators in maintaining the balance between cell proliferation and differentiation and ensure the proper formation and function of root tissues. This review comprehensively presents the roles of WOXs in various root development aspects across multiple plant species, including primary, lateral, adventitious, and crown root development, as well as root hair, rhizoid formation, de novo root regeneration, and root apical meristem maintenance. We also discuss how WOXs regulate root development through various mechanisms in different plant species. Overall, this review provides comprehensive insights into the complex regulatory networks governing plant root growth and the importance of WOXs therein. Understanding WOXs in root development can help improve crop root architecture and stress tolerance and provide insights into the regulatory networks of plant root growth, contributing to plant breeding and agricultural productivity.
