    The Ability of Some Aquatic and Terrestrial Plants to Purify Domestic Wastewater

    Abida Kausar1,*, Noreen Zahra1,2, Humaira Kiran1, Sadia Asim3, Abid Raza4, Ali Raza5,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.8, pp. 2245-2260, 2023, DOI:10.32604/phyton.2023.028264

    Abstract The study aimed to evaluate the ability of some terrestrial and aquatic plants for wastewater purification. Aquatic plants can remove pollutants from wastewater by consuming and accumulating various contaminants in different parts of plants. Different aquatic and terrestrial plants (Rosa sinensis, Typha latifolia, Ocimm bacilicum, Azolla pinnata, and Salvinia molesta) which have the ability to decrease water pollution were utilized in this study. The capability of five different species of plants was investigated by measuring chemical oxygen demand (COD), biological oxygen demand (BOD), electrical conductivity (EC), total dissolved solids (TDS), and pH of the medium. In this research, some aquatic… More >

    In silico Prediction and Analysis of Potential Off-Targets and Off-Target Mutation Detection in StERF3-Gene Edited Potato Plants

    Hafiza Arooj Razzaq1, Siddra Ijaz1,*, Imran Ul Haq2, Faisal Saeed Awan1

    Phyton-International Journal of Experimental Botany, Vol.92, No.8, pp. 2451-2460, 2023, DOI:10.32604/phyton.2023.030501

    Abstract The imperative aspect of the CRISPR/Cas9 system is a short stretch of 20 nucleotides of gRNA that control the overall specificity. Due to the small size, the chance of its multiple occurrences in the genome increases; however, a few mismatches are tolerated by the Cas9 endonuclease activity. An accurate and careful in silico-based off-target prediction while target selection is preferred to address the issue. These predictions are based on a comprehensive set of selectable parameters. Therefore, we investigated the possible off-target prediction and their screening in StERF3 gene-edited potato plants while developing StERF3-loss-of-function mutants using CRISPR/Cas9 More >

    Effect of PEG Incorporation on Physicochemical and in vitro Degradation of PLLA/PDLLA Blends: Application in Biodegradable Implants

    Mochamad Chalid1,*, Gifrandy Gustiraharjo1, Azizah Intan Pangesty1, Alyssa Adyandra1, Yudan Whulanza2, Sugeng Supriadi2

    Journal of Renewable Materials, Vol.11, No.7, pp. 3043-3056, 2023, DOI:10.32604/jrm.2023.026788

    Abstract Polyethylene glycol (PEG) was added at different concentrations to the blend of poly(L-lactic acid) (PLLA) and poly(D,L-lactic acid)(PDLLA) to tailor the properties. The differential scanning calorimetry (DSC) measurement showed that all blends were miscible due to shifting a single glass transition temperature into a lower temperature for increasing PEG content. The DSC, FTIR, and XRD results implied the crystallinity enhancement for PEG content until 8 wt%, then decreased at 12 wt% PEG. The XRD result indicated the homo crystalline phase formation in all blends and no stereocomplex crystal. The in vitro degradation study indicated that… More > Graphic Abstract

    Abstract Determination of the somaclonal variation of in vitro-propagated plants is crucial to determine the appropriate micropropagation protocol and growth regulators for commercial scale multiplication. In this research, nine multiplication media (MM) augmented with different concentrations of 6-benzyl adenine (BA), Kinetin (Kin), and Thidiazuron (TDZ), Three rooting media (RM) supplemented with three levels of α-naphthalene acetic acid (NAA) and three types of soil mixtures (v/v); Coco peat/Vermiculite/Sand (CVS), Peat moss/Perlite/Sand (PPS) and Peat moss/Perlite (PP) were used in the micropropagation protocol of daylily plants. MM2 showed the maximum shoot length and the number of leaves, while MM9… More >

    A Review on Selenium Function under Oxidative Stress in Plants Focusing on ROS Production and Detoxification

    Armin Saed-Moucheshi1,*, Elham Rezaei Mirghaed2

    Phyton-International Journal of Experimental Botany, Vol.92, No.7, pp. 1921-1941, 2023, DOI:10.32604/phyton.2023.027810

    Abstract

    One of the main reasons of the annual reduction in plant production all around the world is the occurrence of abiotic stresses as a result of an unpredicted changes in environmental conditions. Abiotic stresses basically trigger numerous pathways related to oxygen free radicals’ generation resulting in a higher rate of reactive oxygen species (ROS) production. Accordingly, higher rate of oxygen free radicals than its steady state causes to oxidize various types of molecules and compartments within the plants’ cells and tissues. Oxidative stress is the result of high amount free radicals of oxygen interfering with different

    Abstract A review is conducted about the application of the evaporative cooling technology in thermal power plants. Different case studies are considered, namely, evaporative air conditioners, evaporative cooling in direct air-cooled systems, gas turbine inlet cooling, wet cooling towers, and hybrid cooling towers with a crosswind effect. Some effort is provided to describe the advantages related to direct evaporative cooling when it is applied in thermal power plants and illustrate the research gaps, which have not been filled yet. In particular, typical case studies are intentionally used to compare the cooling performances when direct evaporative cooling… More > Graphic Abstract

    AN ULTIMATE SOLUTION TO PHASING OUT FOSSIL FUELS – PART II: AIR-WATER THERMAL POWER PLANTS FOR UTILITY-SCALE POWER PRODUCTION AT LOW TEMPERATURES

    Yiding Cao

    Frontiers in Heat and Mass Transfer, Vol.19, pp. 1-16, 2022, DOI:10.5098/hmt.19.2

    Abstract This paper introduces a novel air-water thermal power plant working at low temperatures and employing hot water as a heat-supply fluid to produce utility-scale power with high second-law efficiency. The air-water power plant uses both air and water as working fluids and employs a direct-contact mass and heat transfer packing to facilitate latent heat (in terms of vapor) and sensible heat transfer from the hot water to moist air for expansion in a gas turbine to produce power. A cycle analysis indicates that with a heat source temperature of around 100o C, the power plant… More >

    Minmin Xiao1, Moxiang Cheng1, Shuangquan Xie1, Xiushuang Wang1, Xingming Hao2, Li Zhuang1,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.6, pp. 1841-1857, 2023, DOI:10.32604/phyton.2023.027369

    Abstract To clarify the characteristics of photoinhibition and the primary defense mechanisms of ephemeral plant leaves against photodestruction under high temperature stress, inhibitors and the technology to determine chlorophyll fluorescence were used to explore the protective effects of D1 protein turnover and the lutein cycle in the high temperature stress of the leaves of three ephemeral plants. The results showed that the maximum light conversion efficiency (Fv/Fm) of the ephemeral plant leaves decreased, and the initial fluorescence (Fo) increased under 35°C ± 1°C heat stress for 1–4 h or on sunny days in the summer. Both… More >

    Abstract Indian medicinal plants are referred to as the “nectar of life” owing to their phytochemicals and bioactive complexes that are beneficial in treating diseases. Coronavirus disease 2019 (COVID-19) is a global health issue without any proper medication. The indigenous plants of India can be exploited to control the precise signs of SARS-CoV-2. The Ministry of AYUSH (Ayurveda, Yoga and Naturopathy, Unani, Siddha, and Homeopathy) has advised routine usage of medicinal plants for COVID-19. Medicinal plants like Zingiber officinalis, Azadirachta indica, Ocimum sanctum, Nigella sativa, Withania somnifera, Curcuma longa, Piper nigrum, Allium sativum, Tinospora cordifolia, etc. have More >
