Cyanobacteria represent one of the most ancient and ecologically significant groups of photosynthetic microorganisms, playing pivotal roles in global carbon and nitrogen cycles, primary productivity, and ecosystem stability. In recent years, they have also emerged as versatile platforms for applications spanning biotechnology, bioenergy, agriculture, environmental remediation, and synthetic biology. Rapid advances in genomics, metabolic engineering, systems biology, and ecological modeling have substantially expanded our understanding of cyanobacterial physiology, diversity, and functional potential, underscoring their relevance in addressing pressing environmental and industrial challenges.

Despite this progress, the field continues to face several critical challenges. These include limitations in genetic tractability across diverse strains, incomplete understanding of regulatory networks under dynamic environmental conditions, scalability issues in industrial applications, and concerns related to harmful algal blooms and toxin production. Furthermore, translating laboratory-scale discoveries into real-world solutions remains a significant bottleneck, compounded by gaps in interdisciplinary integration and standardization of experimental approaches.

This Collection aims to provide a comprehensive platform that captures the breadth of contemporary cyanobacterial research. It seeks to bring together methodological advancements, original research articles, and reviews that collectively reflect both foundational discoveries and translational innovations.

By consolidating cutting-edge discoveries, methods and advancements, this collection will serve as a valuable resource for researchers and industry stakeholders. It will not only enhance conceptual understanding and technical capabilities but also accelerate the development of sustainable, cyanobacteria-based solutions to global challenges.
