    Abstract: 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.

    Abstract: 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".

    Notes: Abstract Segments taken from flower-stalk internodes of Oncidium Sweet Sugar formed somatic embryos and shoot buds directly from wound surfaces or via nodular masses proliferation within 1.5 months, when cultured on a Gelrite-gelled 1/2-MS basal medium supplemented with thidiazuron (0.1–3 mg l−1) in darkness. In light, when subcultured, these nodular masses proliferated into green compact callus, and produced somatic embryos, shoot buds and/or yellowish abnormal structures spontaneously. Supplementing 0.1–1 mg l−1 NAA enhanced embryo formation, but retarded proliferation of shoot buds and yellowish abnormal structures. Somatic embryos that directly formed from wound surfaces of flower stalk explants usually developed into abnormal structures, but the callus-derived embryos could germinate into PLBs and eventually developed to normal plantlets on a hormone-free basal medium for 3–4 weeks. Both the embryo-and shoot bud-derived regenerants developed into healthly plantlets when potted in sphagnum moss and acclimatized in the greenhouse.

    Description: Pomegranate adaptation to abiotic stress conditions has led to its wide dispersion in Pakistan and to the appearance of new, local genotypes. These genotypes are important to characterize for breeding programs aimed towards the production of new cultivars suitable to arid, semi-arid, and moderate weather regions. In this study, eleven pomegranate accessions were investigated for fruit morphological and biochemical traits, and root anatomic adaptation under diverse climates. The commercial accession (Sava) had the maximum fruit weight (373.97 g) compared to accessions KK-I (60.94 g) and KK-II (71.63 g), which were old plantations established since United India. Most of the accessions were juicy with a wood portion index (WPI) ranging from 0.93 to 1.06%; however, the non-commercial accession of Khushab Kanhatti (KK-I) showed the highest WPI (4.38%). A high variation occurred among all accessions for total soluble solids, total sugars, and total ascorbic acid contents with a maximum in accession Sava (16.46 °Brix), TK-II (53.16%), and QW-I (0.68%), respectively. Root anatomical studies in accessions depicted significantly high variation, and accession Sava of semi-arid climate produced maximum root epidermis (97.43 µm2), phloem (2730.78 µm2), and metaxylem (717.77 µm2) area. In contrast, high cortex thickness (104.74 µm), cortex area (462.74 µm2), and vascular area (114,382.10 µm2) was measured in accessions KK-II and KK-III of Khushab district with an arid climate. The germplasm of diverse regions showed a strong association and clustered into two main classes based on fruit morpho-chemical and root anatomical characteristics. These traits are likely to provide clues towards plants adaptation to various growing conditions and can be exploited successfully in crop improvement programs.

    Description: The root of Chinese sage (Salvia miltiorrhiza Bunge) was regarded as top-grade Chinese medicine two thousand years ago, according to Shen Nong Materia Medica. The aim of this study is to develop an easy and reliable means for obtaining tetraploids (4x plants) via thidiazuron-induced direct organogenesis in the presence of colchicine. The resulting 4x plants showed significantly enhanced agronomic traits, including the size of stomata, leaflet, pollen, and seed as well as shoot length, root diameter, number of leaves, and fresh weight of plant. In addition, an obvious reduction of length to width ratio was found in the 4x plants, including stomata, leaflets, pollens, seeds, and roots. The 4x ploidy state of the plants was stable as was proved by evaluation of selection indicators as well as consistent ploidy level at 10th generation plantlets and also on 4x seedlings obtained via self-pollination. The major bioactive compounds, salvianolic acid B, tanshinone I, tanshinone IIA, dihydrotanshinone I and cryptotanshinone, as well as total tanshinones were determined by high performance liquid chromatography (HPLC). The concentrations of dihydrotanshinone I and total tanshinones in the root extract of the 4x plants were significantly higher when compared with the 2x plants. This present study developed a simple and efficient system for inducing and subculture of tetrapolids which have stable ploidy level, enhanced growth characteristics as well as the content of dihydrotanshinone I in the root of S. miltiorrhiza.

    Description: Contamination of soils with heavy metals, particularly cadmium (Cd), is an increasingly alarming environmental issue around the world. Application of organic and inorganic immobilizing amendments such as biochar and gravel sand in combination with metal-tolerant microbes has the potential to minimize the bioavailability of Cd to plants. The present study was designed to identify the possible additive effects of the application of Enterobacter sp. MN17 as well as biochar and gravel sand on the reduction of Cd stress in plants and improvement of growth and nutritional quality of pea (Pisum sativum) plants through the reduction of Cd uptake. Pea seeds were surface sterilized then non-inoculated seeds and seeds inoculated with Enterobacter sp. MN17 were planted in artificially Cd-polluted soil, amended with the immobilizing agents biochar and gravel sand. Application of biochar and gravel sand alone and in combination not only improved the growth and nutritional quality of pea plants by in situ immobilization but also reduced the uptake of Cd by plant roots and its transport to shoots. However, microbial inoculation further enhanced the overall plant health as well as alleviated the toxic effects of Cd on the pea plants. These soil treatments also improved rates of photosynthesis and transpiration. The combined use of biochar and gravel sand with bacterial inoculation resulted in an increase in plant height (47%), shoot dry weight (42%), root dry weight (57%), and 100 seeds weight (49%) as compared to control plants in Cd contaminated soil. Likewise, biochemical constituents of pea seeds (protein, fat, fiber, and ash) were significantly increased up to 41%, 74%, 32%, and 72%, respectively, with the combined use of these immobilizing agents and bacterium. Overall, this study demonstrated that the combined application of biochar and gravel sand, particularly in combination with Enterobacter sp. MN17, could be an efficient strategy for the remediation of Cd contaminated soil. It could support better growth and nutritional quality of pea plants.

    Description: Pomegranate is famous for its health benefiting chemical and biochemical constituent compounds. The present study was undertaken to characterize pomegranate germplasm for its various fruit traits, acids, and sugar profiling through high performance liquid chromatography (HPLC) analysis. Among 11 detected acids and 8 sugars, citric acid and fructose were predominant in 18 domestic and 5 wild genotypes, respectively. Fruit weight, aril weight and wood portion index (WPI) were ranged from 15.82% to 24.42%, 10.99% to 113.78%, and 2.39% to 17.25%, respectively. Genotypes were grouped as sweet, sweet–sour, sour–sweet, and sour based on citric acid contents. Lactic acid and pyruvic acid showed the highest correlation (r = 0.92), however, sour and sweet genotypes had strong association for acids and sugars, respectively. Straddling of dendrogram showed the flow of genetic material in a cultivated location with wild and cultivated pomegranates grouped in different classes, however, wild and sour landraces grouped in the same class with 71% similarity of traits. Based on the observations of the current study, it was concluded that selected wild and arid zones (Multan, Bahawalpur) genotypes are poor in nutrients (acid and sugars) quality, however, genotypes of Rahim-Yar-Khan, Muzafar Garh, and Khyber Pakhtunkhwa have a better composition of sugars and acids.
