IJPB Highlights from Life Sciences at Paris-Saclay University

NLP2: a key transcription factor for nitrogen assimilation and related metabolic pathways, 19/05/23
The interplay between carbon and nitrogen metabolism is a prerequite for maximum growth and yield Using genomic, cellular, metabolic, and reverse genetic approaches, researchers from the NUTS team, in collaboration with the EBI, RDP, IPS2 and the MPI institutes, have found that the NLP2 transcription factorcontrols nitrogen assimilation and metabolic pathways that provide carbon skeleton synthesis and energy supply in response to soil nitrate availability.

TOR: a regulatory factor for plant nitrogen metabolism, 10/5/23
In an article published in Plant Physiology, researchers from the NUTS and SATURNE teams and the PO-Chem platform have highlighted the links between TOR (target of rapamycin) and nitrogen metabolism in the model plant Arabidopsis. In particular, they showed that TOR activation requires both a carbon and a nitrogen source. They also found that the massive accumulation of glutamine resulting from TOR inhibition is related to glutamine synthetase activity.

Platform focus: change of scale with the development of a new Phenoscope-type plant phenotyping robot... in XL size, 06/05/23
Phenoscope robots are designed for growing and phenotyping small plants (typically Arabidopsis thaliana) at the vegetative stage. In particular, these devices can dynamically monitor the growth of the aerial part of the plant while controlling the abiotic environment and minimizing the effects of its variations on plant development. The new Phenoscope (called "Phenoscope XL") will allow small plants to grow beyond the vegetative stage though a complete reproductive cycle (from sowing to seed harvest). This is an important requirement of our scientific community, which is also keen to produce seeds under more reproducible conditions.
