Unraveling Molecular and Hormonal Interactions in Adventitious Root Formation

Adventitious root formation is a vital process in plant development, enabling vegetative propagation and enhancing a plant's ability to survive under adverse conditions. Unlike primary root formation, adventitious roots emerge from non-root tissues such as stems and leaves, thanks to intricate molecular and hormonal cues. These roots play a crucial role in aiding plant establishment, facilitating nutrient uptake, and improving resilience against environmental stresses. The process is influenced by a complex interplay of plant hormones, including auxins, cytokinins, and ethylene, as well as various signaling molecules and transcription factors. Understanding these interactions is key to optimizing root induction in agricultural practices, improving crop propagation, and developing strategies for sustainable agriculture.

Despite its significance, the molecular and hormonal basis of adventitious root formation remains inadequately understood. The precise roles of different hormones and their interactions in the initiation and development stages of adventitious rooting need further elucidation. Current challenges include deciphering the signaling networks and identifying key regulatory genes involved in this process. The primary goal of this Research Topic is to synthesize recent advancements in molecular biology and plant physiology to elucidate the regulatory mechanisms guiding adventitious root development. By achieving this, researchers aim to enhance our ability to manipulate rooting processes for improved plant breeding and propagation, ultimately contributing to food security and sustainable agricultural practices.

This Research Topic invites researchers to submit original research articles, reviews, and perspectives that cover various aspects of adventitious root formation. Key areas of interest include:

• Roles of auxins and other hormones in adventitious rooting.

• Molecular signaling pathways involved in root induction.
