Knowledge of root traits associated with drought tolerance is important for further understanding mechanisms the whole plant. The experiment was designed to investigate effects stress on physiological activities six cultivars (Kentucky‐31, Falcon II, Houndog V, Phoenix, Rebel Jr., and Bonsai) tall fescue ( Festuca arundinacea Schreb.) varying in resistance. Grasses were grown well‐watered or drying (nonirrigated) soil 35 d a greenhouse. Drying reduced length dry mass 0‐ 20‐cm layer all...

Abstract Background Health risk from exposure of perfluorochemicals (PFCs) to wildlife and human has been a subject great interest for understanding their molecular mechanism toxicity. Although much work done, the toxigenicity PFCs remains largely unknown. In this work, non-covalent interactions between perfluorooctane sulfonate (PFOS) serum albumin (SA) DNA were investigated under normal physiological conditions, aiming elucidate PFCs. Results equilibrium dialysis assay, bindings PFOS SA...

Water channel proteins known as aquaporins (AQPs) regulate the movement of water and other small molecules across plant vacuolar plasma membranes; they are associated with tolerance biotic abiotic stresses. In this study, a PIP type AQPs gene, designated GoPIP1, was cloned from Galega orientalis, high value leguminous forage crop. The GoPIP1 gene consists an 870 bp open reading frame encoding protein 289 amino acids, belongs to PIP1 subgroup subfamily. transcript level higher in root G....

Environmental pollution by emerging contaminants, e.g. pharmaceuticals, has become a matter of widespread concern in recent years. We investigated the membrane transport diclofenac and its toxic effects on gene expression development zebrafish embryos. The association with embryos conformed to general partition model at low concentration, coefficient being 0.0033 ml per embryo. At high interaction fitted Freundlich model. Most remained extracellular aqueous solution less than 5% interacting...

Abstract Background Recently, perfluorooctanoic acid (PFOA) has become a significant issue in many aspects of environmental ecology, toxicology, pathology and life sciences because it may have serious effects on the endocrine, immune nervous systems can lead to embryonic deformities other diseases. Human serum albumin (HSA) is major protein component blood plasma called multifunctional carrier its ability bind an unusually broad spectrum ligands. Results The interaction PFOA with HSA was...

Sufficient codominant genetic markers are needed for various investigations in alfalfa since the species is an outcrossing autotetraploid. With newly developed next generation sequencing technology, a large amount of transcribed sequences have been generated and available identifying SSR by data mining. A total 54,278 non-redundant unigenes were assembled through Illumina HiSeqTM 2000 technology. Based on 3,903 unigene sequences, 4,493 SSRs identified. Tri-nucleotide repeats (56.71%) most...

High temperature is a major factor limiting growth of creeping bentgrass ( Agrostis palustris Huds.). Physiological causes turf and quality decline with increasing not well understood. The objective the study was to examine responses carbohydrate metabolisms temperatures in three cultivars. Sods ‘Penncross’, ‘ISI‐AP‐89150’, ‘SR 1020’ were grown chambers exposed sequentially for 20 d each following temperatures: 20, 24, 30, 34, 38°C. Evaluation measurements made at 10 after sequential...

The increased application of nanomaterials has raised the level public concern regarding possible toxicities caused by exposure to nanostructures. interactions nanosized hydroxyapatite (HA) with cytochrome c and hemoglobin were investigated zeta-potential, UV-vis, fluorescence circular dichroism. experimental results indicated that formed via charge attraction hydrogen bond obeyed Langmuir adsorption isotherm. two functional proteins bridged between HA particles aggregate into coralloid...

Information on genetic diversity and population structure of a tetraploid alfalfa collection might be valuable in effective use the resources. A set 336 worldwide genotypes (Medicago sativa subsp. L.) was genotyped using 85 genome-wide distributed SSR markers to reveal alfalfa. Genetic analysis identified total 1056 alleles across marker loci. The average expected heterozygosity polymorphism information content values were 0.677 0.638, respectively, showing high levels cultivated germplasm....

Flavonols are one of the largest groups flavonoids that confer benefits for health plants and animals. Flavonol glycosides predominant present in model legume Lotus japonicus. The molecular mechanisms underlying biosynthesis flavonol as yet remain unknown L. In study, we identified a total 188 UDP-glycosyltransferases (UGTs) japonicus by genome-wide searching. Notably, 12 UGTs from UGT72 family were distributed widely among chromosomes, expressed all tissues, showed different docking scores...

Drought is among the most limiting factors for turfgrass growth. Understanding genetic variations and physiological mechanisms in drought resistance would facilitate breeding management programs to improve resistance. The experiment was designed investigate shoot responses of six tall fescue ( Festuca arundinacea Schreb.) cultivars representing several generations improvement stress. Grasses were grown well-watered or drying (nonirrigated) soil 35 days greenhouse. Net photosynthetic rate (P...
