This book provides comprehensive insights into the existing and emerging trends in orchid biology based on the findings of omics, high-throughput technology, biotechnology, molecular breeding, and genome editing approaches in orchids. It illustrates molecular mechanisms of orchid mycorrhizal symbiosis according to the recent achievements of transcriptomics and bioinformatics studies which accelerate the progress of orchid research with the aid of their high-throughput tools. In this book, a comprehensive view of orchid breeding was presented, and it includes fundamental methods as well as advanced strategies through the combination of several technologies such as genetic engineering, omics, computational biology, and genome editing. These resulting knowledge and tools are highly beneficial for obtaining novel and fascinating varieties in the orchid market which is a competitive industry of global trade. Another interesting content is the focus on the production of orchid bioactive compounds and their values in the field of ethnomedicine. Their sources chiefly came from secondary metabolites and can be enriched through elicitors and produced more efficiently by improved tissue culture protocols and bioreactors. In this edited collection, we provided space for presenting an updated review of in vitro seed germination which is a routine technology for well-trained researchers but can give a complete demonstration for the potential audiences including growers and research beginners. This book collects refined knowledge from a broad source of scientific literature by experts in the field of orchid research and surely is an adequate reference and textbook for students, teachers, and researchers. It includes methods and applications of orchid breeding technology which would gain high attention from growers, breeders, and the related fields of agriculture.

This book presents a complete overview of COVID-19 and provides a series of in-depth analyses of the literature and a comprehensive discussion and perspectives on promising anti-SARS-CoV-2 agents based on the system of ethnopharmacology, which covers Chinese medicine, traditional medicines of India and Africa, Turkish folk medicine, essential oils, and some well-known medicinal plants. In this book, the current status of therapeutic strategies against COVID-19 was summarized and a perspective of potential options for the future was proposed. Based on ethnopharmacology, some well-established traditional herbal formulations and bioactive compounds with anti-virus activity were repurposed for managing COVID-19 and post-illness, including neurological disorders and kidney illness. Using drug discovery tools, promising immune enhancers were explored from phytochemicals against SARS-CoV-2. Nutraceuticals from dietary plants, spices, and fruits with anti-virus and antioxidant activities were recommended to prevent infection or severe illness caused by emerging variants. With the aid of systems pharmacology, researchers have gained insights into possible molecular mechanisms of anti-SARS-CoV-2 activity and have predicted a range of candidate compounds from medicinal plants to combat COVID-19. This book explores the current knowledge of drug discovery and ethnopharmacology for managing coronavirus diseases. The content proved the anti-SARS-CoV-2 activity from natural products and traditional herbal medicines. It contributes to the management of global public health and fits the goal of establishing “Good Health and Well-Being,” which is one of “The Sustainable Development Goals (SDGs) 2030".

Coronaviruses can cause illness, severe disease, and death; e.g. Middle East respiratory syndrome (MERS), severe acute respiratory syndrome (SARS), and COVID-19. Vaccine development and antiviral drugs are challenged by the propensity for viral mutations allowing these viruses to evade such therapies. There are a number of bioactive compounds from natural sources, which can exert health benefits and act as antiviral therapies such as anti-inflammation, anti-oxidative stress, and immune regulation. This book summarizes research on the potential efficacy and underlying mechanisms of bioactive compounds and traditional medicines against SARS-CoV-2. Key Features Summarizes the potential benefits of bioactive therapies for coronaviruses. Focuses on COVID-19, but also covers MERS and SARS. Provides alternatives to vaccines and other antiviral drugs whose efficacy is reduced by viral mutations. Relevant for clinicians and public health officials.
