What is it about?
In Vitro Regeneration and Genetic Transformation of Mungbean, reviews the scientific progress in developing efficient tissue‑culture and transformation systems for Vigna radiata, a major legume crop in Asia valued for its protein content, nitrogen‑fixing ability, and contribution to sustainable agriculture. Conventional breeding of mungbean has been constrained by limited genetic diversity, seasonal dependence, and poor transformation efficiency. The authors synthesize findings on direct and indirect organogenesis using explants such as cotyledonary nodes, shoot tips, hypocotyls, and embryonic axes. Media formulations enriched with cytokinins—particularly BAP and TDZ—are shown to yield high‑frequency shoot regeneration. Somatic embryogenesis is also discussed as a promising alternative for genotype‑specific regeneration. Factors influencing regeneration, including explant age, hormonal balance, and culture conditions, are analyzed to identify reproducible protocols. The review further highlights the need to establish genotype‑independent regeneration systems, optimize liquid‑culture approaches, and overcome transformation bottlenecks that hinder large‑scale propagation and functional genomics. Ultimately, the chapter positions in vitro regeneration and genetic transformation as foundational tools for advancing mungbean improvement, enabling future research in stress tolerance, yield enhancement, and sustainable crop production.

Why is it important?
Developing efficient in vitro regeneration and genetic transformation systems for mungbean is vital because this legume underpins food and nutritional security across Asia. Traditional breeding methods are slow and limited by narrow genetic diversity, making it difficult to introduce traits such as pest resistance, drought tolerance, and higher yield. Reliable regeneration and transformation protocols enable precise gene transfer and functional genomics studies, accelerating the creation of improved cultivars. These advances support sustainable agriculture, reduce dependency on chemical inputs, and help farmers adapt to climate stress.
Perspectives
Future research should focus on refining genotype‑independent regeneration systems, enhancing transformation efficiency, and integrating CRISPR/Cas‑based editing for targeted trait improvement. Combining molecular breeding with tissue‑culture innovations will open pathways for resilient, high‑yielding mungbean varieties. The broader perspective emphasizes that such biotechnological progress is not merely technical—it represents a strategic step toward global food sustainability and agricultural resilience.
