IJPB Highlights from Life Sciences at Paris-Saclay University

Arabidopsis exhibits significant natural variability in its response to complex abiotic stresses, such as the combination of water and nitrogen deficiencies, 6/8/24  
In nature or in the field, stresses often combine in a complex dynamic. In a study published in The Plant Cell, several scientists from the IJPB VAST, SATURNE, and NUTS teams, with support from the IJPB PO-Pheno and PO-Chem platforms, as well as the POPS platform from IPS2, collaborated to reveal the extent of the natural diversity present in the species Arabidopsis thaliana in response to water stress and nitrogen deficiency, both individually and in combination. This multi-omic characterization work (phenomic, transcriptomic, and metabolomic) emphasizes the challenge of defining a "universal response" in this species.

The process of pollen death in cytoplasmic male sterility of Arabidopsis thaliana is better understood through innovative cytological approaches,  23/5/24 
In flowering plants, cytoplasmic male sterility (CMS) is the inability to produce viable pollen, induced by specific mitochondrial genes. CMS is widely used for hybrid seed production in crops. In a study published in Journal of Experimental Botany, scientists from the IJPB OrgaRepro, MiN, SC-Info, PO-Cyto, and PO-VASC teams, in collaboration with colleagues from the Universities of Münster (Germany) and Tokyo (Japan), used cytological approaches to gain a better understanding of the pollen abortion process in CMS of Arabidopsis thaliana.

Prediction of plant cell phenotypes through resource allocation modeling at the cellular scale, 23/5/24
Understanding and predicting plant cell responses under complex environmental conditions are major challenges in plant biology and predictive biology. In a study published in Metabolic Engineering, scientists from the MaIAGE unit and the IJPB teams PHYGERM, SATURNE, and VAST developed a resource allocation model at the cellular and molecular scales for the photosynthetic cell of the Arabidopsis thaliana leaf, based on the constraint-based modeling method known as Resource Balance Analysis (RBA).
