Improved efficacy of neonicotinoid in tablet formulation ...

2020-1-8 · Neonicotinoid insecticides are used for preventing insects from transmitting plant viruses. This group of chemicals are easily taken up by plants and translocated to different tissues and are applicable for soil treatment in sustained-release tablets, which greatly reduces environmental contamination compared to foliar spray. The goal of this study was to examine …

Climate Effects on Subsoil Carbon Loss Mediated by Soil ...

Subsoils store at least 50% of soil organic carbon (SOC) globally, but climate change may accelerate subsoil SOC (SOCsub) decomposition and amplify SOC-climate feedbacks. The climate sensitivity of SOCsub decomposition varies across systems, but we lack the mechanistic links needed to predict system-specific SOCsub vulnerability as a function of measurable …

Potential toxic elements in stream sediments, soils and ...

2017-3-25 · The Alto da Várzea radium mine (AV) exploited ore and U-bearing minerals, such as autunite and torbernite. The mine was exploited underground from 1911 to 1922, closed in 1946 without restoration, and actually a commercial area is deployed. Stream sediments, soils and water samples were collected between 2008 and 2009. Stream sediments are mainly …

An investigation on the efficiency of low-cost adsorbents ...

2020-9-11 · The groundwater samples were found to be contaminated with high concentrations of uranium (U) in Punjab state as well as in few other locations of India. U being chemically toxic can deteriorate health when ingested. Hence, there is a need to remove U from contaminated water using an efficient, cheap and user friendly method. A study was initiated to investigate the …

Linking Mineralogy to Lithogeochemistry in the Highland ...

The coarse muscovite-altered sample is strongly depleted in calcium oxide and Ba and moderately depleted in Sr, Zn, Li, and Na 2 O . The white-mica–chlorite facies, hosted in the Bethsaida granodiorite, are consistently enriched in SiO 2 (9%), K 2 O (90%), and Cu (1,876 ppm) and depleted in CaO (–11%), Na 2 O (–49%), and Sr (–267 ppm).

Soybean Root System Architecture Trait Study through ...

Abstract. We report a root system architecture (RSA) traits examination of a larger scale soybean accession set to study trait genetic diversity. Suffering from the limitation of scale, scope, and susceptibility to measurement variation, RSA traits are tedious to phenotype. Combining 35,448 SNPs with an imaging phenotyping platform, 292 ...

UV crosslinked mRNA-binding proteins captured from leaf ...

2016-11-3 · The complexity of RNA regulation is one of the current frontiers in animal and plant molecular biology research. RNA-binding proteins (RBPs) are characteristically involved in post-transcriptional gene regulation through interaction with RNA. Recently, the mRNA-bound proteome of mammalian cell lines has been successfully cataloged using a new method called …

Hydrogen peroxide mediates abscisic acid‐induced HSP70 ...

The gas exchange of attached leaves was measured using an infrared gas analyser, Li‐Cor‐6400 (Li‐Cor Inc., Lincoln, NE, USA), at a temperature of 25 °C, a relative humidity of 85%, a cuvette air flow rate of 500 mL min −1 and an ambient CO 2 concentration of 380 μ mol mol −1.

Effects of ectomycorrhizal fungi (Suillus variegatus) on ...

2021-4-10 · A better understanding of non-structural carbohydrate (NSC) dynamics in trees under drought stress is critical to elucidate the mechanisms underlying forest decline and tree mortality from extended periods of drought. This study aimed to assess the contribution of ectomycorrhizal (ECM) fungus (Suillus variegatus) to hydraulic function and NSC in roots, stems, and leaves of …

Polyelectrolyte-Assisted Dispersions of Reduced Graphite ...

Dispersion of graphene and related materials in water is needed to enable sustainable processing of these 2D materials. In this work, we demonstrate the capability of branched polyethylenimine (BPEI) and polyacrylic acid (PAA) to stabilize reduced graphite oxide (rGO) dispersions in water. Atomic force microscopy colloidal probe measurements were carried out to investigate the …

2016-8-1 · The Bantou watershed covers approximately 205 km 2 in northwest Xiamen, Fujian Province, China (Yu et al., 2014).The local climate is subtropical monsoon with a warm season (average atmospheric temperature >20 °C) from April to October and a wet and cold season (with typhoons, average temperature <20 °C) from November to March.The watershed is composed …

Feedback Regulation of Xylem Cytokinin Content Is ...

2007-2-2 · Cytokinin, a mobile plant hormone, can influence shoot branching but its precise role is unclear. In several species, direct application of cytokinin to axillary buds promotes outgrowth (e.g. Sachs and Thimann, 1964 ) and endogenous cytokinin levels have been found to rise in and around axillary buds during growth initiation ( Li et al., 1995 ...

The rhizosphere of tropical grasses as driver of soil ...

1. Introduction. Defined as the volume of soil directly affected by roots, the rhizosphere provides a chemical environment that boosts biological activity (Rovira and Davey, 1973).This biogeochemical environment differs from that of the bulk soil due to the release of metabolic products by roots and microorganisms, which can lead to more intense mineral alteration …
