The study of plant callus, a dedifferentiated cell mass, provides crucial insights into cellular totipotency, regeneration, and developmental plasticity. While significant strides have been made in understanding callus induction and organogenesis in model dicots such as Arabidopsis, monocots present unique challenges and characteristics due to their distinct signaling pathways, hormonal responses, and epigenetic controls. Recent studies have begun to unravel these complexities, highlighting both overlapping and divergent mechanisms that contribute to callus formation and regeneration in these two groups of plants. Despite progress, many gaps remain, particularly in the molecular, physiological, and structural aspects of these processes.

This Research Topic aims to bring together pioneering research on the foundational mechanisms of callus formation and differentiation in monocots and dicots. By focusing on themes such as hormonal crosstalk, transcriptional networks, epigenetic reprogramming, and comparative analyses across plant groups, the Research Topic seeks to deepen our understanding of these biological phenomena. Our objective is to enhance knowledge of callus development mechanisms to stimulate innovative applications in plant tissue culture, biotechnology, and agriculture. By catalyzing advancements in these areas, we hope to contribute to the broader field of plant sciences.
To gather further insights into callus formation and regeneration, we welcome articles addressing, but not limited to, the following themes:
• Hormonal Regulation of Callus Induction: From Signaling Pathways to Genomic Responses
• Gene networks driving totipotency and regeneration
• Epigenetic modifications influencing callus formation
• Comparative Genomics of Callus Induction in Monocots and Dicots
• Transcriptional networks and their role in organogenesis

The submission types include Research articles, reviews, short communications, and methodological papers.
