Project description:In Aspergillus nidulans, nitrogen and carbon metabolism are under the control of wide-domain regulatory systems, including nitrogen metabolite repression, carbon catabolite repression. Transcriptomic analysis of the wild type strain grown under different combinations of carbon and nitrogen regimes was performed, to identify differentially regulated genes. Carbon metabolism predominates as the most important regulatory signal but for many genes, both carbon and nitrogen metabolisms coordinate regulation.
Project description:Expression data of Arabidopsis thaliana wild-type plants and quadruple nas T-DNA insertion mutants grown under different Fe supply conditions
Project description:his study investigates how Arabidopsis thaliana seeds integrate genetic and environmental stress during development. We analyzed wild-type (WT) and cruabc triple seed-storage-protein (SSP) mutants to test whether proteome rebalancing—the ability to maintain overall amino acid and protein composition despite loss of SSPs—persists under additional stress. Plants were subjected to low nitrogen, high nitrogen, or drought treatments applied exclusively during seed filling. We measured seed physiological traits, carbon and nitrogen content, fatty-acid composition, free and protein-bound amino acids, and performed DIA-based total proteomics.
Project description:Phosphate (Pi) deficiency alters root hair length and frequency as a means of increasing the absorptive surface area of roots. Three partly redundant single R3 MYB proteins, CAPRICE (CPC), ENHANCER OF TRY AND CPC1 (ETC1) and TRIPTYCHON (TRY), positively regulate the root hair cell fate by participating in a lateral inhibition mechanism. To identify putative targets and processes that are controlled by these three transcription factors (TFs), we conducted transcriptional profiling of roots from Arabidopsis thaliana wild-type plants, and cpc, etc1 and try mutants grown under Pi-replete and Pi-deficient conditions using RNA-seq.
