**Preface**

It is with great pleasure that I introduce the reprint of the Special Issue entitled "Plants as a Promising Biofactory for Bioactive Compounds". Originally published in *Life*, this collection of research articles showcases the extraordinary potential of nature's green laboratories for the production of bioactive compounds.

Plants, with their remarkable ability to synthesize an astonishing array of bioactive compounds, have always been a source of inspiration and wonder. These bioactive compounds, often referred to as phytochemicals, encompass a wide spectrum of chemical classes and are known for their beneficial effects on human health, as well as their role in plant defense and ecological interactions. In addition to natural compounds, plants can also be genetically engineered to produce valuable recombinant proteins and enzymes for therapeutic and industrial applications. This Special Issue explores the diverse ways in which plants serve as remarkable biofactories for producing active compounds and enzymes with potential applications in medicine, agriculture, and industry.

As the global demand for sustainable sources of bioactive compounds continues to grow, the need for innovative solutions becomes ever more urgent. This reprint aims to serve as a valuable resource for researchers, academicians, students, and industry professionals who are interested in the fascinating world of plant-based bioactive compounds. The potential of plants as biofactories is vast and ever-evolving, and I am confident that the insights provided in this Special Issue will inspire further research and innovation in the field.

Finally, I want to extend my gratitude to the authors for their exceptional contributions to this Special Issue and to the reviewers for their dedication to maintaining the highest standards of research. I hope that this compilation inspires further exploration and collaboration, driving us closer to a future in which plants, as biofactories, are harnessed to their full potential for the betterment of society and the planet.
