Evaluating the Combined Effects of Erythromycin and Levofloxacin on the Growth of Navicula sp. and Understanding the Underlying Mechanisms

open access: yesPlants, 2023
Navicula sp., a type of benthic diatom, plays a crucial role in the carbon cycle as a widely distributed algae in water bodies, making it an essential primary producer in the context of global carbon neutrality.

Chloride application weakens cadmium immobilization by lime in paddy rice soil

open access: yesEcotoxicology and Environmental Safety, 2022
Contamination of agricultural products by cadmium (Cd) is a global health problem, causing chronic abnormalities. The consumption of rice, the most-consumed foods, is an important exposure route of Cd to human body. Chloride (Cl-) is reported to increase

Differences in morphological and physiological features of citrus seedlings are related to Mg transport from the parent to branch organs

open access: yesBMC Plant Biology, 2021
Background In this study, we aimed to test the hypothesis that magnesium (Mg) remobilization in citrus plants is regulated by Mg supply and contributes to differences in the growth of the parent and branch organs.

Effects and mechanisms of Cd remediation with zeolite in brown rice (Oryza sativa)

open access: yesEcotoxicology and Environmental Safety, 2021
The effects of zeolite amendment on the Cd absorption and accumulation of two varieties of rice, ZY-18 (Zheyou 18, hybrid indica) and DL-5 (Donglian 5, conventional indica), planted in a slightly Cd-contaminated paddy soil, and the associated mechanisms ...

Regulating environmental threats [PDF]

open access: yesEnvironmental and Resource Economics, 2007
Environmental consequences of natural resource exploitation often entail threats of future occurrences of detrimental abrupt events rather than (or in addition to) inflicting a damage gradually. The possibility of abrupt occurrence of climate-change related calamities is a case in mind.

Environmental Statistics and Optimal Regulation [PDF]

open access: yesBiophysical Journal, 2014
Any organism is embedded in an environment that changes over time. The timescale for and statistics of environmental change, the precision with which the organism can detect its environment, and the costs and benefits of particular protein expression levels all will affect the suitability of different strategies-such as constitutive expression or ...

Environmental Regulation of Yersinia Pathophysiology [PDF]

open access: yesFrontiers in Cellular and Infection Microbiology, 2016
Hallmarks of Yersinia pathogenesis include the ability to form biofilms on surfaces, the ability to establish close contact with eukaryotic target cells and the ability to hijack eukaryotic cell signaling and take over control of strategic cellular processes. Many of these virulence traits are already well-described.

Brassinosteroids and iron plaque affect arsenic and cadmium uptake by rice seedlings grown in hydroponic solution

open access: yesBiologia Plantarum, 2018
Brassinosteroids (Brs) have drawn wide attention due to their protective role against toxicity of heavy metals in plants. To better understand the role of Br in arsenic (As) and cadmium (Cd) uptake by rice plants, a hydroponic experiment was conducted to

Alterations in promoter interaction landscape and transcriptional network underlying metabolic adaptation to diet

open access: yesNature Communications, 2020
Metabolic adaptation to different diets results in changes to gene expression. Here, the authors characterise the chromatin landscape and transcriptional network in mice on a diet of high saturated fat, compared to a diet high in carbohydrate, finding a ...

Solar-driven methanogenesis with ultrahigh selectivity by turning down H2 production at biotic-abiotic interface

open access: yesNature Communications, 2022
While the combination of synthetic and biological systems offers an appealing strategy for solar-to-fuel conversion, such hybrid systems typically suffer from low selectivity.
