| Process ID | Gene number | Process name |
| GO:0000160 | 19 | A conserved series of molecular signals found in prokaryotes and eukaryotes; involves autophosphorylation of a histidine kinase and the transfer of the phosphate group to an aspartate that then acts as a phospho-donor to response regulator proteins. |
| GO:0001402 | 0 | Relaying of environmental signals promoting filamentous growth. |
| GO:0001560 | 2 | Any process whereby external signals modulate the frequency, rate or extent of cell growth, the irreversible increase in size of a cell over time. |
| GO:0001881 | 0 | The process by which receptor molecules are returned to an active state and in an active cellular location after they have been stimulated by a ligand. An active state is when the receptor is ready to receive a signal. |
| GO:0002764 | 1 | The cascade of processes by which a signal interacts with a receptor, causing a change in the level or activity of a second messenger or other downstream target, and ultimately leading to the activation, perpetuation, or inhibition of an immune response. |
| GO:0007166 | 3 | Any series of molecular signals initiated by the binding of an extracellular ligand to a receptor on the surface of the target cell. |
| GO:0007227 | 0 | The series of molecular signals that are initiated by the transmembrane protein Smoothened. In the presence of a Hedgehog signaling molecule, the Patched protein no longer inhibits the activity of Smoothened, and Smoothened signals via the Hedgehog signaling complex to activate downstream components of the Hedgehog signaling pathway. |
| GO:0007242 | 98 | A series of reactions within the cell that occur as a result of a single trigger reaction or compound. |
| GO:0009401 | 0 | The uptake and phosphorylation of specific carbohydrates from the extracellular environment; uptake and phosphorylation are coupled, making the PTS a link between the uptake and metabolism of sugars; phosphoenolpyruvate is the original phosphate donor; phosphoenolpyruvate passes the phosphate via a signal transduction pathway, to enzyme 1 (E1), which in turn passes it on to the histidine protein, HPr; the next step in the system involves sugar-specific membrane-bound complex, enzyme 2 (EII), which transports the sugar into the cell; it includes the sugar permease, which catalyzes the transport reactions; EII is usually divided into three different domains, EIIA, EIIB, and EIIC. |
| GO:0032005 | 0 | The series of molecular signals that bring about the relay, amplification or dampening of a signal generated in response to a cue, such as starvation or pheromone exposure, in organisms that undergo conjugation with cellular fusion. |
| GO:0060395 | 0 | The cascade of processes by which a signal interacts with a receptor, causing a change in the activity of a SMAD protein, and ultimately effecting a change in the functioning of the cell. |
| GO:0060863 | 0 | The cascade of processes by which a signal interacts with a receptor, causing a change in the level or activity of a second messenger or other downstream target, and ultimately modulating the rate, or extent of floral organ abscission. |
