“…Environmental factors such as drought, salinity, light intensity, high/low temperature, heavy metals and soil nutrients status have adverse effects on plant growth and photosynthesis. Osmolytes accumulation, antioxidants production and higher SMs accumulation are some of the plant responses to harsh environmental conditions (Mahajan et al 2020). Secondary metabolites are chemical defense molecules that secreted when plants are under biotic and abiotic stresses (Alvarado et al 2019).…”

Bioactive compounds of medicinal plants have a wide range of applications in pharmaceutical, food and other industries. In vitro culture systems have great potential for sustainable production of bioactive compounds of medicinal plants. In the present study, the individual and combined effects of a stress tolerance-inducing (salicylic acid) and a stress-inducing elicitor (polyethylene glycol) were evaluated on regeneration e ciency, antioxidants activity and phytochemical pro le of in vitro shoot cultures of ajowan. Different concentrations of salicylic acid (SA) (0, 10, 20, 40, 80 µM) and polyethylene glycol (PEG 6000) (0, 1, 2, 5%) were added to the shoot regeneration Murashige and Skoog medium containing Kin (1.5 mg/L) and NAA (0.25 mg/L) plant growth regulators. Salicylic acid reduced the adverse effect of PEG treatment on number of regenerated shoots and in vitro rooting. The activities of catalase, superoxide dismutase, and peroxidase enzymatic antioxidants were signi cantly increased in SA + PEG treated plants. The gas chromatography-mass spectrometry (GC-MS)-pro ling revealed quantitative and qualitative phytochemical differences between control and SA + PEG treated plants. The greatest means of p-cymene and thymol bioactive compounds were obtained from in vitro shoots treated with 5% PEG + 40 µM SA. The inter-simple sequence repeats (ISSR) markers proved the genetic stability of in vitro regenerated plants. The presented protocol is useful for large-scale sustainable production of secondary metabolites (SMs) of medicinal plants. The same strategy (stress tolerance-inducing elicitor + stress-inducing elicitor) is applicable to increase valuable SMs in other production systems such as hydroponic, greenhouse and eld conditions.

“…Such a result is in accordance to our results which showed a greater frequency of MP species in alvars and wooded meadows as compared with oodplain meadows. Both water shortage and shade tolerance of MP species can be linked to the increased synthesis of useful secondary metabolites during environmental stress [15,41]. MP species also tend to be more common and anthropophyte than the other plant species in the community.…”

Background: Semi-natural grasslands as valuable ecosystems are significant for their high biodiversity, cultural importance and landscape values. Quantitative information about medicinal plants in semi-natural grasslands facilitates the evaluation of ecosystem services of these plant communities. Methods: Different literature sources and floristic inventory databases were used to assess the ratio and frequency of medicinal plant species in several Estonian grassland types and the impact of management on these values assessed both in Estonian and Japanese case studies. Lists of medicinal plant species according to different definition scenarios is included as Supplementary Material. Principal Component Analysis was applied for environmental preferences of medicinal plant species compared to other vascular plant species in the semi-natural grasslands.Results: The ratio of medicinal plant species in local total plant species list was the largest in alvars, followed by floodplain and wooded meadows. The average number of medicinal plant species per study plot in wooded meadows and alvars was about twice that found in naturally growing broadleaved forest (according to the most detailed MP species list 7.2, 7.8 and 4.3, respectively). Fertilization of Estonian wooded meadows had no significant impact on medicinal plant species ratio, but decreased the proportion of medicinal plant biomass in total yield. Estonian coastal meadows had a short list of medicinal plant species and the impact of management quality depended therefore on adopted definition scenario. In Japanese Miscanthus sinensis grassland case mowing or burning+mowing combination should be preferred to favor medicinal plant species number. Principal Component Analysis revealed that MP species are more drought-tolerant, common and anthropophyte than the rest of studied grassland species.Conclusions: Alternative usage of herbaceous plant species from semi-natural grasslands is a promising option to achieve sustainable development goals and increase public awareness. Further close cooperation of ecologists, economists and pharmacists is required to guarantee fair and sustainable trade of this ecosystem service in the future.

“…Setiap tumbuhan mengembangkan ciri adaptasi yang berbeda untuk menghadapi stress lingkungan sekitar habitatnya seperti salinitas, panas, kekeringan, genangan, logam berat dan faktor nutrient (Fayçal Boughalleb et al, 2014;Mahajan et al, 2020). Studi terhadap pengaruh stress lingkungan terhadap tumbuhan dan adaptasi yang dilakukan tumbuhan merupakan subjek penelitian yang sangat berkembang cepat di dunia (Alkhatib et al, 2018) karena berbagai stress lingkungan yang ada menjadi faktor pembatas bagi produktivitas tumbuhan (Nio Song and Banyo, 2011;Osakabe and Osakabe, 2012).…”

Penurunan produktivitas inilah yang selanjutnya dapat menurunkan kegagalan panen dan mengancam sektor agrikultur dunia (Mahajan et al, 2020). Tak hanya mengancam ketahanan pangan, tumbuhan yang berpotensi sebagai obat herbal juga akan terpengaruh karena metabolit sekunder yang dihasilkan sanbat bergantung pada kondisi lingkungan baik berupa faktor biotik maupun abiotik.…”

Adaptasi dilakukan oleh tumbuhan demi kelangsungan hidupnya di lingkungan yang sangat dinamis. Salah satu jenis adaptasi yang dikembangkan adalah adaptasi anatomis pada akar, batang, maupun daun. Tujuan review artikel ini yakni memberikan langkah yang dapat dilakukan manusia dalam membantu tumbuhan untuk menjaga adaptasi anatomisnya sehingga dapat mendorong pertumbuhan dan perkembangan tumbuhan di bawah stress lingkungan. Review ini didasarkan pada telaah pustaka pada artikel-artikel ilmiah yang membahas tentang adaptasi anatomis tumbuhan terhadap perbedaan stress lingkungan. Berdasarkan kajian yang dilakukan, perlu adanya upaya penelitian lebih lanjut guna menjaga tumbuhan tetap lestari di bawah stress lingkungan yang semakin menantang. Kata kunci: adaptasi; anatomi; stress lingkungan
