Abstract Growth of eukaryotic cells is regulated by the target rapamycin (TOR). The strongest activator TOR in metazoa amino acid availability. established transducers sensing to are absent plants. Hence, a fundamental question how achieved photo-autotrophic organisms. Here we demonstrate that plant Arabidopsis does not sense sulfur-containing cysteine itself, but its biosynthetic precursors. We identify kinase GCN2 as sensor carbon/nitrogen precursor availability, whereas limitation sulfur...
Abstract Deprivation of mineral nutrients causes significant retardation plant growth. This is associated with nutrient‐specific and general stress‐induced transcriptional responses. In this study, we adjusted the external supply iron, potassium sulfur to cause same shoot Nevertheless, limitation by individual resulted in specific morphological adaptations distinct shifts within root metabolite fingerprint. The metabolic affected key metabolites primary metabolism stress‐related...
The deficiency of nutrients has been extensively investigated because its impact on plant growth and yield. So far, the effects a combined nutrient limitation have rarely analyzed, although such situations are likely to occur in agroecosystems. Iron (Fe) is prerequisite for many essential cellular functions. Its availability easily becoming limiting thus higher plants evolved different strategies cope with Fe deficiency. Sulfur (S) an macro-nutrient responses triggered by shortage well...
Abstract Plants, unlike animals, respond to environmental challenges with comprehensive developmental transitions that allow them cope these stresses. Here we discovered antagonistic activation of the Target Rapamycin (TOR) kinase in Arabidopsis thaliana roots and shoots is essential for nutrient deprivation-induced increase root-to-shoot ratio improve foraging mineral ions. We demonstrate sulfate limitation-induced downregulation TOR activates autophagy, resulting enhanced carbon allocation...
The uptake of sulfate by roots and its reductive assimilation mainly in the leaves are not only essential for plant growth development but also defense responses against biotic abiotic stresses. latter functions result stimulus-induced fluctuations sulfur demand at cellular level. However, maintenance acclimation homeostasis local systemic levels is fully understood. Previous research mostly focused on signaling response to external supply roots. Here we apply micrografting Arabidopsis...
