Sugar sensing and signaling.
Plants, restricted by their environment, need to integrate a wide variety of stimuli with their metabolic activity, growth and development. Sugars, generated by photosynthetic carbon fixation, are central in coordinating metabolic fluxes in response to the changing environment and in providing cells and tissues with the necessary energy for continued growth and survival. A complex network of me...
متن کاملSpecialized Sugar Sensing in Diverse Fungi
S. cerevisiae senses glucose and galactose differently. Glucose is detected through sensors that reside in the cellular plasma membrane. When activated, the sensors initiate a signal-transduction cascade that ultimately inactivates the Rgt1 transcriptional repressor by causing degradation of its corepressors Mth1 and Std1. This results in the expression of many HXT genes encoding glucose transp...
متن کاملSugar sensing and signaling in plants
Sugars are ubiquitous and critical components for general metabolism. These primary products from photosynthesis affect most, if not all, processes in plant cells by providing skeletons for organic compounds and storing energy for chemical reactions. Sugars also serve as critical signaling molecules in relation to both cellular metabolic status and biotic and abiotic stress response (Rolland et...
متن کاملA Redundant and Diverse Transmembrane Signaling Network
G proteins, or GTP-binding proteins, are a family of proteins that act as links in signaling chains across cell membranes in all eukaryotic cells.1-3 These pathways usually include a receptor molecule, a G protein as the signal transducer, and an effector enzyme or ion channel that can be activated or inhibited by the G protein. A large variety of stimuli reaching the cell surface, including nu...
متن کاملDiverse two-dimensional input functions control bacterial sugar genes.
Cells respond to signals by regulating gene expression. The relation between the level of input signals and the transcription rate of the gene is called the gene's input function. Because most genes are regulated by more than one signal, the input functions are usually multidimensional. To understand cellular responses, it is essential to know the shapes of these functions. Here, we map the two...
