Root growth is correlated to plants fitness and productivity, and adaption to stressful environments. Its growth is a complex and precisely regulated process that involves the interplay of multiple phytohormones. Jasmonates (JAs), as key defense hormones, not only participate in the response of plants to biotic and abiotic stresses, but also play a critical role in root growth and development. This review provides insights into the progress being made in understanding the role of JA in root growth and development, highlighting the integration of JA with other phytohormones, including auxin, ethylene, cytokinin, abscisic acid, gibberellin, and brassinosteroid. These hormone signaling pathways form a complicated regulatory network to shape the root system structure. Understanding the regulatory network of JA-regulated root growth will be instrumental for elucidating the molecular mechanism underlying plant growth-defense tradeoff, which will accelerate future crop breeding programs to obtain cultivars that combine robust defenses while maintaining normal yields.
