What are feedback systems in biology? Feedback systemsplay an important role in organisms, enabling smooth function. Feedback systems help all living organisms, from tiny bacteria to humans, regulate life's ess
1.14.2.3.1Positive and negative feedback Positive and negative feedbacks can be illustrated by considering a device engineered by humans: the steam engine. Steam engines commonly possess a ‘governor.’ This is an arrangement whereby a valve is controlled by weighted arms that revolve, the revoluti...
A new study reveals a positive feedback loop between asymmetric distribution of the hormone auxin and the cell wall pectin conformations underpinning cell elongation and tissue bending.doi:10.1016/j.cub.2021.01.031Kris VissenbergCurrent Biology
such as signaling processes. Positive feedback loops, composed of species and reactions, are necessary for bistability, and generally for multi-stationarity, to occur. These loops are therefore often used to

Conversely, "positive" is widely used to describe optimistic attitudes, affirmative answers ("a positive response"), or conditions ("positive feedback"), reflecting a broader range of applications beyond numerical value. 11 In the context of test results, "positive" often indicates the presence ...
Background An important goal of biology is to identify genetic modifications that have led to evolutionarily significant changes in phenotype. In the case of protein-coding genes, this means identifying mutations that were fixed by selection to alter properties such as the activity of enzymes or the...
Each of the circuits was built out of regulatory elements known from studies of gene regulation in prokaryotes, and each was some variation of a ‘double-negative’ feedback circuit. A simple example of such a circuit is shown in Fig. 1a. Suppose that there are two gene products, A and ...
Unravelling biosphere feedback mechanisms is crucial for predicting the impacts of global warming. Soil priming, an effect of fresh plant-derived carbon (C) on native soil organic carbon (SOC) decomposition, is a key feedback mechanism that could release
