A Review of Water Quality Factors that Affect Nickel Bioavailability to Aquatic Organisms: Refinement of the Biotic Ligand Model for Nickel in Acute and Chronic Exposures.

Environ Toxicol Chem 2021 May 4. Epub 2021 May 4.

NiPERA, Durham, NC, 27713.

A review of nickel (Ni) toxicity to aquatic organisms was conducted to determine the primary water quality factors that affect Ni toxicity, and to provide information for the development and testing of a biotic ligand model (BLM) for Ni. Acute and chronic data for 66 aquatic species were compiled for this review. This review found that dissolved organic carbon (DOC) and hardness act as toxicity modifying factors (TMFs) because they reduced Ni toxicity to fish and aquatic invertebrates and these effects were consistent in acute and chronic exposures.

Small molecule natural products in human nasal/oral microbiota.

J Ind Microbiol Biotechnol 2021 Feb 6. Epub 2021 Feb 6.

Department of Chemical and Biomolecular Engineering, University of California, Berkeley, Berkeley 94720, USA.

Small molecule natural products are a chemically diverse class of biomolecules that fulfill myriad biological functions, including autoregulation, communication with microbial neighbors and the host, interference competition, nutrient acquisition, and resistance to oxidative stress. Human commensal bacteria are increasingly recognized as a potential source of new natural products, which may provide insight into the molecular ecology of many different human body sites as well as novel scaffolds for therapeutic development. Here, we review the scientific literature on natural products derived from residents of the human nasal/oral cavity, discuss their discovery, biosynthesis, and ecological roles, and identify key questions in the study of these compounds.

Tree growth responses to temporal variation in rainfall differ across a continental-scale climatic gradient.

PLoS One 2021 4;16(5):e0249959. Epub 2021 May 4.

School of Biological Sciences, The University of Western Australia, Perth, Western Australia, Australia.

Globally, many biomes are being impacted by significant shifts in total annual rainfall as well as increasing variability of rainfall within and among years. Such changes can have potentially large impacts on plant productivity and growth, but remain largely unknown, particularly for much of the Southern Hemisphere. We investigate how growth of the widespread conifer, Callitris columellaris varied with inter-annual variation in the amount, intensity and frequency of rainfall events over the last century and between semi-arid (<500 mm mean annual rainfall) and tropical (>800 mm mean annual rainfall) biomes in Australia.

Biochemical evidence of epicuticular wax compounds involved in cotton-whitefly interaction.

PLoS One 2021 4;16(5):e0250902. Epub 2021 May 4.

Center of Excellence in Molecular Biology (CEMB), University of the Punjab, Lahore, Pakistan.

Sucking insects require a surface of plants on which the legs and the eggs of insects will adhere and to which insect mouthparts will access. The primary plant protection against insects is their surface property, which hinders the attachment of the insect's legs and eggs. The epicuticular waxes chemistry influences the fine structure of the cuticular surface. Read More

Development and evaluation of a target enrichment bait set for phylogenetic analysis of oomycetes.

Mycologia 2021 May 4:1-12. Epub 2021 May 4.

Ottawa Research and Development Centre, Agriculture and Agri-Food Canada, 960 Carling Avenue, Ottawa, Ontario, K1A 0C6, Canada.

Target enrichment is a term that encompasses multiple related approaches where desired genomic regions are captured by molecular baits, leaving behind redundant or non-target regions in the genome, followed by amplification and next-generation sequencing of those captured regions. A molecular bait set was developed based on 426 single-copy, oomycete-specific orthologs and 3 barcoding genes. The bait set was tested on 27 oomycete samples (belonging to the Saprolegniales, Albuginales, and Peronosporales) derived from live and herbarium specimens, as well as control samples of true fungi and plants.
