Abstract Drought is a severe environmental constraint, causing a significant reduction in crop productivity across the world. Salicylic acid (SA) is an important plant growth regulator that helps plants cope with the adverse effects induced by various abiotic stresses. The current study investigated the potential effects of SA on drought tolerance efficacy in two barley (Hordeum vulgare) genotypes, namely BARI barley 5 and BARI barley 7. Ten-day-old barley seedlings were exposed to drought stress by maintaining 7.5% soil moisture content in the absence or presence of 0.5, 1.0 and 1.5 mM SA. Drought exposure led to severe… More >

Abstract

Arsenic (As) contaminated food chains have emerged as a serious public concern for humans and animals and are known to affect the cultivation of edible crops throughout the world. Therefore, the present study was designed to investigate the individual as well as the combined effects of exogenous silicon (Si) and sodium nitroprusside (SNP), a nitric oxide (NO) donor, on plant growth, metabolites, and antioxidant defense systems of radish (Raphanus sativus L.) plants under three different concentrations of As stress, i.e., 0.3, 0.5, and 0.7 mM in a pot experiment. The results showed that As stress reduced the

Abstract Senescence is the last developmental process in plant, which has an important impact on crop yield and quality. In this study, a stable hereditary early-senescence line BC64 was isolated from the high-generation recombinant inbred lines of 93-11 and Wuyunjing7 (W7). Genetic analysis showed that the premature aging phenotype was controlled by a dominant gene derived from 93-11. By linkage analysis, the gene was primarily mapped in the region between marker B4 and B5 near the centromere of chromosome 4, described as ES(4). Through multiple backcrossing with W7, the near-isogenic line of ES(4) (NIL-ES(4)) was obtained. Compared More >

Abstract Fibrosis is the end-stage change of damaged tissues in various human diseases, which can lead to permanent scarring or organ malfunction. Hypoxia leads to oxidative stress, mitochondrial dysfunction, and inflammation in dysfunctional organs and tissues. Oxidative stress resulting from the overproduction of reactive oxygen species plays a central role in the fibrosis of injured organs. This review addresses the updated knowledge of the relationship between hypoxia and tissue fibrosis mediated by the reactive oxygen species pathway. Moreover, novel anti-fibrotic strategies are discussed, which may suppress reactive oxygen species and organ fibrosis. More >

Abstract Schisandrin B (Sch B) is a monomer with anti-cancer and anti-inflammatory effects, which are isolated from the plant Schisandra chinensis (Turcz) Baillon. We investigated the anti-gastric cancer (GC) effects of Sch B and its underlying molecular mechanisms. The Cell Counting Kit-8 assay was used to determine the effects of Sch B on the viability of GC and normal cell lines. Hoechst/propidium iodide staining and flow cytometry were used to assess the apoptosis induction of Sch B. Western blotting was used to evaluate the effects of Sch B on downstream apoptotic proteins. The DCFH-DA fluorescent probe was… More >

Abstract Liver cancer is the seventh most common malignant tumor in the world and is the second highest cause of death due to cancer. Quercetin, a flavonoid with low toxicity, widely exists in various fruits and vegetables. It has the potential to be a therapeutic agent against various cancers. This study aimed to demonstrate the anti-tumor effect of quercetin on HepG2 cells. Quercetin suppressed the HepG2 cell proliferation in a dose-dependent manner in cell viability assay. Induction of cell apoptosis was confirmed by apoptotic cells population (sub-G1 peak) detected by flow cytometer. A decrease in mitochondrial More >

Abstract

Cadmium (Cd) causes oxidative stress, which leads to the oxidation of various biomolecules by the production of reactive oxygen species (ROS) to facilitate programmed cell death (PCD). The antioxidant defense system fails to detoxify ROS when it is produced in excess. Nitric oxide (NO), a gaseous free radical and a phytohormone, regulates various physiological processes of plants. Therefore, this work was undertaken to study the effects of the application of exogenous sodium nitroprusside (SNP, a NO donor) on growth parameters, oxidative stress, accumulation of secondary metabolites, and activities of antioxidant enzymes under Cd stress.

Abstract Due to the unpredictable climate change, drought stress is being considered as one of the major threats to crop production. Wheat (Triticum aestivum L. cv. BARI Gom-26) being a dry season crop frequently faces scarcity of water and results in a lower yield. Therefore, this experiment aims to explore the role of different organic amendments (OAs) in mitigating drought stress-induced damage. The pot experiment consisted of different organic amendments viz. compost, vermicompost and poultry manure @0.09 kg m⁻² soil, biochar @2.5% w/w soil and chitosan @1% w/w soil which was imposed on the plants grown under both… More >

Abstract

The interaction between the nucleus and the different organelles is important in the physiology of the plant. Reactive oxygen species (ROS) are a by-product of the oxidation of organic molecules to obtain energy by the need to carry out the electron transfer between the different enzymatic complexes. However, they also have a role in the generation of what is known as retrograde signaling. This signal comes from the different organelles in which the oxidation of molecules or the electron transference is taking place such as mitochondria and chloroplasts. Furthermore, ROS can also induce the release

Abstract

Paeonia ostii is an economically important oil crop, which has been widely cultivated in the middle and lower reaches of the Yangtze River in China in recent years. Although P. ostii is highly adaptable to the environment, the prolonged high summer temperature in this region severely inhibits its growth, which adversely affects seed yield and quality. In this study, P. ostii plants were subjected to 20°C/15°C (day/night) and 40°C/35°C (day/night) temperatures for 15 days. The changes in physiological and biochemical indicators of P. ostii under high-temperature stress were initially investigated. The results showed that with the deepening of leaf
