The effect of polymyxin on plant roots [PDF]

open access: yesArchives of Biochemistry and Biophysics, 1955
Abstract Root growth of young seedlings of barley and other species was substantially inhibited when placed in 5–10 p.p.m. solutions of the antibiotic, polymyxin B. The inhibiting effect was suppressed by simultaneous presentation of an excess of calcium ions. Polymyxin solutions of the same concentration had no adverse effect on germination.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Effects of nitrogen fertilization on beech and Norway spruce and on the preformed defences of their fine roots against fungal pathogens [PDF]

open access: yes, 2005
The main objective of this thesis was to determine the effect of nitrogen fertilization on beech and Norway spruce and on the pre-formed defences of their fine roots to fungal pathogens.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Disentangling who is who during rhizosphere acidification in root interactions: combining fluorescence with optode techniques

open access: yesFrontiers in Plant Science, 2013
Plant–soil interactions can strongly influence root growth in plants. There is now increasing evidence that root–root interactions can also influence root growth, affecting architecture and root traits such as lateral root formation.

Carboxylates and the uptake of ammonium by excised maize roots [PDF]

open access: yes, 1975
The effect of carboxylates (organic acid anions) on NH 4 uptake was studied by changing the carboxylate level of roots prior to uptake experi ments. Succinate was the most effective stimulator of ammonium uptake.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
