Abstract

Cutting-induced adventitious root (AR) formation is crucial for vegetative propagation, a key method that produces plants identical to parent. However, many woody plants pose challenges for vegetative propagation due to difficulties in AR formation. Hormones play important roles during AR formation, with auxin serving as the key regulator and interacting with other hormones. In this review, we summarize the molecular events and hormone functions involved in AR formation in woody plants. A deeper understanding of these processes could enhance the design and manipulation of techniques to improve vegetative propagation in woody plants, ultimately leading to greater economic benefits.
