Elucidating how a population of non-growing bacteria generates mutations improves our understanding of phenomena like antibiotic resistance, bacterial pathogenesis, genetic diversity and evolution. To evaluate mutations that occur in nutritionally stressed non-growing bacteria, we have employed the strain B. subtilis
In cells, organs and whole organisms, nutrient sensing is key to maintaining homeostasis and adapting to a fluctuating environment1. In many animals, nutrient sensors are found within the enteroendocrine cells of the digestive system; however, less is known about nutrient
We present a gnotobiotic system for microbiota reconstitution on Arabidopsis thaliana under contrasting iron availability. This system induces iron starvation in plants by providing an unavailable form, mimicking conditions in alkaline soils. Inoculation of taxonomically diverse bacteria reconstitutes plants with
The activation and regulation of target genes by the tumour-suppressor p53 dictates the fate of a cell, with cell cycle arrest or apoptosis being two distinct outcomes. PERP (p53 apoptosis effector related to PMP-22), a p53 transcriptional target, is induced
In this work, the contribution of NMDA receptors to the antidepressant-like effect of adenosine in the forced swimming test (FST) was investigated. The pretreatment of mice with NMDA or D-serine was able to prevent the anti-immobility effect of either adenosine
