As a result of climate change, salinity has become major abiotic stress that reduces plant growth and crop productivity worldwide. A variety endophytic bacteria alleviate salt stress; however, their ecology biotechnological potential not been fully realized. To address this gap, collection 117 were isolated from wild populations the herb Thymus vulgaris in Sheikh Zuweid Rafah North Sinai Province, Egypt, identified based on 16S rRNA gene sequences. The endophytes highly diverse, including 17...
Land conversion to cropland is one of the major causes severe soil erosion in Africa. This study assesses current extent and related risk Rwanda, a country that experienced most rapid population growth expansion Africa over last decade. The land cover use (LCLU) map Rwanda 2015 was developed using Landsat-8 imagery. Based on obtained LCLU spatial datasets precipitation, properties elevation, rate assessed at 30-m resolution, Revised Universal Soil Loss Equation (RUSLE) model. According...
Sustained β-adrenergic activation induces cardiac fibrosis characterized by excessive deposition of extracellular matrix (ECM). Prostaglandin E2 (PGE2) receptor EP4 is essential for cardiovascular homeostasis. This study aims to investigate the roles cardiomyocyte (CM) and fibroblast (CF) in isoproterenol (ISO)-induced fibrosis. By crossing EP4f/f mice with α-MyHC-Cre or S100A4-Cre mice, this work obtains CM-EP4 knockout (EP4f/f-α-MyHCCre+) CF-EP4 (EP4f/f-S100A4Cre+) mice. The both genders...
Deforestation and natural grassland conversion to agricultural land use constitute a major threat soil water conservation. This study aimed at assessing the status of cover (LCLU) in Lake Kivu basin, its related impacts terms erosion by using Universal Soil Erosion Equation (USLE) model. The results indicated that basin is exposed risk with mean annual rate 30 t·ha−1, only 33% total non-water area associated tolerable loss (≤10 t·ha−1·year−1). Due both factors (abundant tropical...
With high resolution and wide coverage, satellite precipitation products like Global Precipitation Measurement (GPM) could support hydrological/ecological research in the Tianshan Mountains, where spatial heterogeneity of is high, but rain gauges are sparse unevenly distributed. Based on observations from 46 stations 2014–2015, we evaluated accuracies three products: GPM, Tropical Rainfall Mission (TRMM) 3B42, Climate Prediction Center morphing technique (CMORPH), Mountains. The estimates...
Abstract. The influence on soil erosion by different bedrock bareness ratios, rainfall intensities, underground pore fissure degrees and duration are researched through manual simulation of microrelief characteristics karst bare slopes crack construction in combination with artificial experiment. results show that firstly, when the intensity is small (30 50 mm h−1), no bottom load loss produced surface, surface runoff, runoff sediment production increased increasing intensity. Secondly,...
Soil erosion has become a serious problem in recent decades due to unhalted trends of unsustainable land use practices. Assessment soil is prominent tool planning and conservation water resource ecosystems. The Universal Loss Equation (USLE) was applied Nyabarongo River Catchment that drains about 8413.75 km² (33%) the total Rwanda coverage small part Southern Uganda (about 64.50 km²) using Geographic Information Systems (GIS) Remote Sensing technologies. estimated annual actual loss...
Essential oils have been evaluated as appropriate phytotoxins with mechanisms of action that are different from those synthetic herbicides applied in weed management activities, but little is known about the effect Ambrosia artemisiifolia essential oil (EO) on weeds. Here, chemical composition A. EO was analyzed using a Gas Chromatography-Mass Spectrometry system. and phytotoxic activities against monocot (Poa annua, Setaria viridis) dicot (Amaranthus retroflexus, Medicago sativa) species...
The allelopathy definition accepted by the International Allelopathy Society is any process or phenomenon via which organisms such as plants, microorganism, viruses, and fungi release specific metabolites, known allelochemicals, into environment that affect growth development of other surrounding resulting in mutual inhibition promotion organisms. donor plants either self-induced induced external biotic abiotic factors. factors may determine types quantities allelochemicals released a...
Alkaloids with allelopathic activity are not as well-known other allelochemicals. Our study revealed that total alkaloids from seeds of the medicinal plant Peganum harmala L. possessed significant growth inhibitory effect on four treated plants, dicot plants (lettuce and amaranth) being more sensitive than tested monocot (wheat ryegrass). Further investigation led to isolation harmaline harmine main active ingredients in P. seeds. Harmaline exerted potent effects seedling especially dicots,...
The present investigation studied the chemical composition of essential oils extracted from Dracocephalum integrifolium Bunge growing in three different localities northwest China and evaluated phytotoxic, antimicrobial insecticidal activities as well their major constituents, i.e., sabinene eucalyptol. GC/MS analysis revealed presence 21–24 compounds oils, representing 94.17–97.71% entire oils. Monoterpenes were most abundant substances, accounting for 85.30–93.61% oils; among them,...
The chemical profile of Thymus proximus essential oil (EO) and its allelopathic, phytotoxic, insecticidal activity was evaluated. Carvacrol, p-cymene, γ-terpinene were detected as the major components EO, representing 85.9% total oil. About 50 g fresh plant material T. in a 1.5-L air tight container completely inhibited seed germination Amaranthus retroflexus Poa anuua . Meanwhile, EO exhibited potent phytotoxic activity, which resulted 100% failure both test species when 2 mg/ml (for A. ) 5...
The spindle assembly checkpoint (SAC) functions as a surveillance mechanism to detect chromosome misalignment and delay anaphase until the errors are corrected. SAC is thought control mitosis meiosis, including meiosis in mammalian eggs. However, it remains unknown if eggs of nonmammalian vertebrate species also regulated by SAC. Using novel karyotyping technique, we demonstrate that complete disruption microtubules Xenopus laevis oocytes did not affect bivalent-to-dyad transition at time...
The aim of this study was to identify bioactive compounds from leaves the invasive plant Xanthium spinosum and assess their phytotoxic activity. Activity-guided fractionation led isolation 6 compounds: xanthatin (1), 1α,5α-epoxyxanthatin (2), 4-epiisoxanthanol (3), 4-epixanthanol (4), loliolide (5) dehydrovomifoliol (6). Of them, 2⁻6 were isolated X. for first time. structures 1⁻6 elucidated on basis extensive NMR studies ESI-MS measurements as well comparison with literature data. All...
As a critical ecosystem type, wetlands have received extensive attention from scholars worldwide. Previous studies mostly taken the entire wetland as research object, and there is lack of differentiated on subsystems. Ponds are vital component ecosystems, they widely distributed, provide high ecological service value, related to many functions; however, not attracted sufficient scholarly attention. This study divided ponds into three categories according differences in geographic location,...
The chemical profile and the phytotoxicity of Artemisia absinthium essential oil (EO) were investigated to evaluate its potential value as a biopesticide for food safety purposes. A total 54 compounds identified in A. EO, with most abundant constituents being eucalyptol (25.59%), linalool (11.99%), β-myrcene (10.05%). linalool, mixture three major components exhibited potent suppressive activity against four receiver species; however, showed much weaker effect. Bioassay-guided fractionation...
Abstract The semi‐arid Loess Plateau is a central zone of Chinese rain‐fed farming. Drought and soil erosion are the two major obstacles to restrict economic development in this Plateau. traditional conservation agriculture runoff have been developed for several decades, which reduced water loss improved rainwater utilization efficiency certain extent. However, its regulative role very much limited, problems production, such as severe seasonal drought shortage, low productivity, fragile...
Genetic selection strategies towards increased prolificacy have resulted in more and littler size incidences of impaired fetal development. Low birth weight (LBW) piglets, with long-term alterations structure, physiology metabolism, lower survival rates poor growth performance. The aim the study was to compare plasma, liver skeletal muscle contents neutral amino acids (NAA) intestinal expression NAA transporters between LBW high (HBW) suckling Huanjiang mini-piglets. Forty piglets either or...
