{"title":"Biodiversity and Indigenous Medicinal Knowledge of North-East India: Navigating Climate Change Impacts on Medicinal Plants for Conservation and Advancement -","authors":"Amie Chakma, None Manikantan Pappuswamy, None Aditi Chaudhary, None Arun Meyyazhagan, None A. Vijaya Anand, None Balamuralikrishnan Balasubramanian","doi":"10.14719/pst.2374","DOIUrl":"https://doi.org/10.14719/pst.2374","url":null,"abstract":"The northeastern region of India holds the sixth position among the world's 25 biodiversity hotspots, covering approximately 8% of the nation's total land area, which amounts to 262,060 square kilometers. Situated in the eastern Himalayas, any alterations in this biodiversity-rich area can have significant and far-reaching consequences. Indigenous tribes of this region believe in the remarkable healing properties of certain medicinal plants, and within its diverse population of around 225 communities, each tribal and sub-tribal group possesses distinct traditional knowledge. Capturing and harnessing this indigenous wisdom by scientists and researchers could unlock new avenues for progress, particularly within the pharmaceutical sector. Climate change stands as one of the paramount global environmental challenges. Predictions indicate that by the close of the 21st century, the Earth's average temperature might rise by anywhere between 0.3 to 4.8 °C, accompanied by a potential sea level increase of 26 to 82 cm. These climate shifts could have adverse effects on the abundance and accessibility of medicinal plants, potentially leading to species extinction. Moreover, the impact of climate change could extend beyond availability to also encompass alterations in the pharmacological properties of various plants, particularly those found in alpine environments. This discussion underscores the importance of existing knowledge, critical analyses, challenges, opportunities, and the immense value of medicinal plants. It emphasizes the intersection of changing climate and the vulnerability of medicinal plant resources, necessitating a comprehensive understanding of these effects in the context of the North Eastern region of India. To address these challenges, there is a pressing need for in-depth research on the geographical distribution of plant communities and strategies to enhance the secondary synthesis of critically endangered medicinal plants under the current climate change scenarios.","PeriodicalId":20236,"journal":{"name":"Plant Science Today","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135878925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was conducted in the Koraput and Semiliguda blocks of Koraput district, Odisha, with a sample size of 120. The study used an ex-post facto research approach that combined random and purposeful sampling methods. While the gram panchayats, villages, and respondents were chosen at random, the district and blocks were purposefully chosen. The responses were obtained from each individual respondent through a structured interview schedule. Regarding adoption, the majority (75%) of off-season vegetable growers had medium adoption levels. With mean scores of 2.93, 3.00, 3.00, 2.87, 2.75, and 1.25 in regards to production, management, conservation, marketing, training, and capacity building, as well as supporting data, farmers have more adoption of land suitability, crop rotation, across-slope ploughing, input availability, discussion meetings, and crop insurance, respectively. To augment off-season vegetable production in the state in general and Koraput in particular, the latest proven and viable technology for off-season vegetable production needs to be diffused through various extension activities to accelerate its adoption. Again, the new, tried-and-true vegetable-growing techniques should be disseminated through several extension programmes to speed their adoption.","PeriodicalId":20236,"journal":{"name":"Plant Science Today","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135878607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the circadian clock in humans malfunctions or is misaligned with environmental signals, the timing of the sleep-wake cycle is altered and several circadian rhythm sleep disorders result. Due to the Earth's rotation on its axis, predictable environmental changes are anticipated by complex processes. The combined term for these systems is the circadian clock. The circadian rhythm regulates photosynthesis, photoperiodism, and photoperiodism, making it the \"primary controller of plant life.\" The circadian clock is made up of post-translational alterations to core oscillators, epigenetic tweaks to DNA and histones, and autoregulatory feedback loops in transcription. In addition, the circadian clock is cell-autonomous and regulates the circadian rhythms of distinct organs. Biochemical elements such as photosynthetic products, mineral nutrients, calcium ions, and hormones are used by the core oscillators to communicate with one another. Arabidopsis is utilized to identify clock-related genes that govern plant growth, germination, pollination, flowering, abiotic and biotic stress responses, and more. The biological cycles of all species, notably humans, are undoubtedly impacted by other elements, including high altitude and changing ecosystems, in addition to the ones already stated. Although it hasn't yet published any experimental or scientific evidence to support them, the implication that living things have lives does appear inescapable. Hence, the present study elaborates on the higher plants related to the circadian clock.","PeriodicalId":20236,"journal":{"name":"Plant Science Today","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135938712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The morphological discrepancies and nomenclature of Ocimum L. are jumbled up, the same species has been named multiple times by multiple authors. It culminates in erroneous evaluation for taxonomy-based research. Our indignation highlights the taxonomic alterations and modifications that Ocimum L. has undergone since primeval period. The genus's classical to the modern taxonomic transition has not been studied hitherto. The aim is to provide precise information on the antecedent and contemporary stature of Ocimum L. The present study attempts to provide taxonomic clarity for a highly economic genus in order to enhance the commercial perspective and efficiency of selective breeding practices. The present study emphasizes identifying samples with their type, protologue, and herbarium specimen and extricate between ecotype, morphotype, and chemotypes. Molecular taxonomy can provide better insights and transparency. But for a better exposition, such studies must revolve around correctly identified species. The selection of representatives from different populations of the same species can help understand the consistency of vegetative and reproductive characteristics. In this review, few corrections have been provided for misidentified or mistaken species. The species with incorrect nomenclature has been identified and corrections have been suggested. For a better understanding, habit photographs of Indian Ocimum L. have been furnished and morphological features (vegetative and reproductive) for proper diagnosis and correlation has been provided. Specimen examination either through physical or digital herbaria is an obligatory criterion for an error-free taxonomic inquest. Our findings will help to achieve accuracy while interpreting the genus and its species.

The latex derived from these plants contains irritants to the skin and finds application in wart removal. Additionally, it serves as a source for crafting fish and arrow poisons. Literature substantiates the utilization of these plants in the treatment of diverse ailments including menstrual issues, diarrhea, colds, fevers, as well as an array of skin conditions such as warts, sores, boils, dermatitis, psoriasis, eczema, and sunburn. Moreover, they contribute to wound healing. Certain species within the Euphorbia genus, classified under Euphorbiaceae, exhibit properties as anti-herpetic and antitumor agents against polio, rhinoviruses, and coxsackievirus. In the realm of Ayurveda, specific plant latex from select species is employed in the preparation of surgical threads for Kshara sutra therapy. This Ayurvedic approach serves as a minimally invasive para-surgical procedure in the management of anorectal piles or fistula. Remarkably, various di- and tri-terpenes obtained from the latex exhibit robust antimicrobial activity against both bacterial and fungal strains. Moreover, the di-terpenoids sourced from Euphorbia species display anti-inflammatory properties along with noteworthy cytotoxic and anticancer activities. The focal objective of this review is to present a contemporary overview encompassing traditional applications, phytochemical constituents, and the antimicrobial potential of ten latex-producing plants within the Euphorbia genus.","PeriodicalId":20236,"journal":{"name":"Plant Science Today","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136072148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rheumatoid arthritis affects people all around the world, and its prevalence and impact differ by place. The World Health Organisation (WHO) estimates that 0.5% to 1% of the global population has rheumatoid arthritis. To decrease the progression of rheumatoid arthritis, disease-modifying anti-rheumatic medications (DMARDs) such as methotrexate and sulfasalazine are used. TNF inhibitors and IL-6 inhibitors are two examples of biologic DMARDs that target specific immune system components. Nonsteroidal anti-inflammatory drugs (NSAIDs) and analgesics help manage pain and inflammation while corticosteroids provide short-term relief during flares. Treatment strategies are tailored to the individual, and talking with a healthcare expert is essential for effective management. Herbal therapies are regarded to offer an advantage over synthetic pharmaceuticals for the treatment of rheumatoid arthritis due to their natural approach, potential symptom relief, holistic approach to health, and individualised therapy possibilities. However, scientific data supporting their effectiveness is sparse and variable, and their quality and safety can vary. Before adopting herbal therapies as part of a treatment plan, it is critical to check with a healthcare expert. Because of their natural chemicals with anti-inflammatory and analgesic characteristics, medicinal herbs may aid rheumatoid arthritis.
