Mycobacterium avium Possesses Extracellular DNA that Contributes to Biofilm Formation, Structural Integrity, and Tolerance to Antibiotics. [PDF]

PLoS ONE, 2015
Mycobacterium avium subsp. hominissuis is an opportunistic pathogen that is associated with biofilm-related infections of the respiratory tract and is difficult to treat. In recent years, extracellular DNA (eDNA) has been found to be a major component of

Impact of Heavy Metal Pollution on the Biotic and Abiotic Components of the Environment

South Asian Journal of Research in Microbiology, 2022
The environment comprises of biotic and abiotic components interacting as a system. The environment also contains organic and inorganic minerals in optimal concentration required by living organisms for growth, development, and metabolic activities. Due to anthropogenic activities and some natural occurrences, the availability of these elements has ...

Magnetically Actuated Drops‐on‐Stilts Microrobots for Transport and Delivery of Hydrophobic Cargo

Advanced Materials Interfaces, EarlyView.
Iron oxide nanoparticles and oil droplets in external magnetic fields form “drops‐on‐stilts” microrobots that transport hydrophobic cargo. Tunable nanoparticle–droplet interactions generate stilt‐like structures. Field rotation enables walking, obstacle navigation, and collective motion.

Transcriptome Changes Reveal the Molecular Mechanisms of Humic Acid-Induced Salt Stress Tolerance in Arabidopsis

Molecules, 2021
Humic acid (HA) is a principal component of humic substances, which make up the complex organic matter that broadly exists in soil environments. HA promotes plant development as well as stress tolerance, however the precise molecular mechanism for these ...

Climate Change Threatens Micronutrient Density of European Winter Wheat

Advanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Chromosome-level genomes of two Bracteacoccaceae highlight adaptations to biocrusts

Nature Communications
Biological soil crusts (biocrusts) cover the majority of the world’s dryland ground and are a significant component of the vegetation-free surface of the planet.

Influence of some environmental variables on the diversity and distribution of aquatic oligochaetes (Clitellata: Annelida) in the Nyong estuary (Atlantic coast, southern Cameroon)

Scientific African
Tropical estuarine ecosystems are subject to strong anthropogenic pressures, with the direct consequence of declining or lost biodiversity. An essential and little-known biological component of these estuarine ecosystems is the population of oligochaete ...

The Status of Abiotic Components in Aquatic Environment of Khaste Lake, Pokhara

Prithvi Journal of Research and Innovation, 2021
Water is one of the most significant natural resources. In plants and animals, different physiological processes like respiration, photosynthesis, absorption of nutrients and other metabolic process get influenced by the amount of availability of water. This study has been conducted to evaluate water quality of Khaste Lake, Pokhara.

Single‐Cell Transcriptomics Reveals FLS2‐Dependent Hypoxia Signaling and ERF13‐Mediated Transcription During flg22‐Triggered Immunity

Advanced Science, EarlyView.
This study employs sc‐RNA sequencing, genetics, and phenotyping to systematically map the cell‐type‐specific immune responses triggered by flg22. It reveals FLS2‐dependent transcriptional reprogramming in epidermal and mesophyll cells, and uncovers crosstalk between immune and hypoxia signaling pathways.

UV-induced carbon monoxide emission from living vegetation [PDF]

Biogeosciences, 2013
The global burden of carbon monoxide (CO) is rather uncertain. In this paper we address the potential for UV-induced CO emission by living terrestrial vegetation surfaces. Real-time measurements of CO concentrations were made with a cavity-enhanced laser
