Phytoalexins are antimicrobial substances of low molecular weight produced by plants in response to infection or stress, which form part of their active defense mechanisms. It is now clear that phytoalexins exhibit toxicity across much of the biological spectrum, prokaryotic and eukaryotic. Starting in the 1950s, research on phytoalexins has begun with biochemistry and bio-organic chemistry, resulting in the determination of their structure, their biological activity as well as mechanisms of their synthesis and their catabolism by microorganisms. Elucidation of the biosynthesis of numerous phytoalexins has also permitted the use of molecular biology tools for the exploration of the genes encoding enzymes of their synthesis pathways and their regulators. This has led to potential applications for increasing plant resistance to diseases. Phytoalexins display an enormous diversity belonging to various chemical families such as isoflavones, isoflavanones, pterocarpans, isoflavans, flavanones, coumestans, furanoacetylenes, phenylpropanoids, steroid glycoalkaloids, norsesquiterpenoids/sesquiterpenoids, coumarins, diterpenes, ent-kaurane-related diterpenoids, acidic sesquiterpenoids, 3-deoxyanthocyanidins, naphthaldehydes, indoles and stilbenes.Research papers dealing with all aspects of phytoalexins, including structure elucidation; chemical synthesis; methods for phytoalexin analysis in plant extracts or biological fluids; biosynthesis studies including modulation of phytoalexin synthesis; engineering of phytoalexin biochemical pathways in plants and microbes; biological activities; structure/activity relationships; phytoalexin metabolism in planta and by micro-organisms; roles and ATP Binding Cassette (ABC) transporters or Multi-Drugs Efflux (MDE) transporters are welcome for inclusion in this Special Issue of Molecules. Review articles, particularly those dealing with the themes mentioned above are also particularly welcome for inclusion.

Abiotic stresses such as drought, high salt, cold, heat, UV radiation, heavy metal pollution, etc., are increasingly responsible for restricting plant growth and agricultural production and are becoming more alarming due to threats from global climate change. To combat these threats, this new 3-volume set provides a comprehensive understanding of the mechanisms that mediate biosynthesis, accumulation, and degradation of plant metabolites to improve crop production and enhance abiotic stress tolerance in plants. Volume 1: Secondary Metabolites in Environmental Stress Tolerance focuses exclusively on the diverse secondary metabolites that play a major role in the adaptation of plants to the environment and in overcoming stress conditions as well as their implications for enhancing tolerance mechanisms. The book presents available information on the protective roles rendered by a wide array of antioxidative secondary metabolites and their regulation during diverse environmental stress. Volume 2: Trace Elements in Environmental Stress Tolerance throws light on the different inorganic trace elements, including metal nanoparticles, that help to deal with environmental stresses. While these elements at high level create considerable phytotoxicity and halt metabolic and enzymatic activity, they also promote growth and development in limited quantity, so that they have significant potential in revamping plant morphology and physiology under stressed conditions. Hence, optimum concentration management of these elements can help to mitigate world hunger and contribute toward sustainable agriculture and food security under challenging environments. Volume 3: Sustainable Approaches for Enhancing Environmental Stress Tolerance focuses on the agronomic and biochemical approaches as well as biotechnological and high-throughput technologies, including the prospects of genetic engineering, epigenetics and the latest CRISPR/Cas technology, in generating stress-tolerant plants. The volume provides a clear roadmap for the implementation of techniques for improving abiotic stress tolerance in plants for better sustenance.

The book offers an integrated overview of plant–pathogen interactions. It discusses all the steps in the pathway, from the microbe–host-cell interface and the plant’s recognition of the microbe to the plant’s defense response and biochemical alterations to achieve tolerance / resistance. It also sheds light on the classes of pathogens (bacteria, fungus and viruses); effector molecules, such as PAMPs; receptor molecules like PRRs and NBS-LRR proteins; signaling components like MAPKs; regulatory molecules, such as phytohormones and miRNA; transcription factors, such as WRKY; defense-related proteins such as PR-proteins; and defensive metabolites like secondary metabolites. In addition, it examines the role of post-genomics, high-throughput technology (transcriptomics and proteomics) in studying pathogen outbreaks causing crop losses in a number of plants. Providing a comprehensive picture of plant-pathogen interaction, the updated information included in this book is valuable for all those involved in crop improvement.

This book sheds new light on the role of various environmental factors in regulating the metabolic adaptation of medicinal and aromatic plants. Many of the chapters present cutting-edge findings on the contamination of medicinal plants through horizontal transfer, as well as nanomaterials and the biosynthesis of pharmacologically active compounds. In addition, the book highlights the impacts of environmental factors (e.g., high and low temperature, climate change, global warming, UV irradiation, intense sunlight and shade, ozone, carbon dioxide, drought, salinity, nutrient deficiency, agrochemicals, waste, heavy metals, nanomaterials, weeds, pests and pathogen infections) on medicinal and aromatic plants, emphasizing secondary metabolisms. In recent years, interest has grown in the use of bioactive compounds from natural sources. Medicinal and aromatic plants constitute an important part of the natural environment and agro-ecosystems, and contain a wealth of chemical compounds known as secondary metabolites and including alkaloids, glycosides, essential oils and other miscellaneous active substances. These metabolites help plants cope with environmental and/or external stimuli in a rapid, reversible and ecologically meaningful manner. Additionally, environmental factors play a crucial role in regulating the metabolic yield of these biologically active molecules. Understanding how medicinal plants respond to environmental perturbations and climate change could open new frontiers in plant production and in agriculture, where successive innovation is urgently needed due to the looming challenges in connection with global food security and climate change. Readers will discover a range of revealing perspectives and the latest research on this vital topic.

It defines their functional uses while evaluating the advantages and disadvantages of their application in various sectors. Essential oils have been used by global communities for centuries, for different purposes such as medicinal, flavoring, preservatives, perfumery, aromatherapy, dentistry, cosmetics, insecticide, fungicide, and bactericide, among others. Essential oils are natural and biodegradable substances, usually non-toxic or with low toxicity to humans. Essential oils are botanical products that have volatile nature, known for their special odor, and found to be effective in the treatment of oxidative stress, cancer, epilepsy, skin allergies, indigestion, headache, insomnia, muscular pain, respiratory problems, etc. Essential oils principally enhance resistance to abiotic stress and protection against aquatic herbivores. They possess antimicrobial, antifungal, antitumor, and antioxidant properties. Essential oils are known to be volatile and susceptible to degradation from various ambient conditions, including temperature, air, light, and humidity, which limits their applications. Encapsulation is a proven technique that can protect essential oils and enable their use in various applications. This book aims to provide current knowledge on the chemical structure, therapeutic, and biological activities of essential oils, as well as to describe their functional uses and assess the benefits and drawbacks of their usage in various fields. By exploring the latest research on essential oils and their encapsulation, this book offers valuable insights and practical guidance for anyone interested in the science and application of these fascinating compounds.
