Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an abiotic (not derived from living organisms) stimulus.
A factor of an experiment is a controlled independent variable; a variable whose levels are set by the experimenter. A factor is a general type or category of treatments. Different treatments constitute different levels of a factor.
Note that this term is in the subset of terms that should not be used for direct gene product annotation. Instead, select a child term or, if no appropriate child term exists, please request a new term. Direct annotations to this term may be amended during annotation QC.

A process in which a symbiont alters or subverts the response of its host to an abiotic (non-living) stimulus. The host is defined as the larger of the organisms involved in a symbiotic interaction.
Note that this term should not be used for direct annotation. Please consider one of the more specific descendants, GO:0140297 ; DNA-binding transcription factor binding, GO:0140296 ; general transcription initiation factor binding or GO:0001221 ; transcription coregulator binding.
Sigma factors act as the promoter specificity subunit of eubacterial and plant plastid multisubunit RNA polymerases, whose core subunit composition is often described as alpha(2)-beta-beta-prime. Although sigma does not bind DNA on its own, when combined with the core to form the holoenzyme, the sigma factor binds specifically to promoter elements. The sigma subunit is released once elongation begins.
Any process that activates Factor XII (Hageman factor). Factor XII is a protein synthesized by the liver that circulates in an inactive form until it encounters collagen or basement membrane or activated platelets (as occurs at the site of endothelial injury). Factor XII then undergoes a conformational change (becoming factor XIIa), exposing an active serine center that can subsequently cleave protein substrates and activate a variety of mediator systems. Factor XII is a participant in the clotting cascade as well as the kinin cascade.
A secreted multiprotein complex composed of 4 proteins, regulating group size during aggregation in cooperative development. An example of this complex is found in Dictyostelium discoideum.

An abiotic disease is a physiological, non-parasitic, non-infectious disease caused by numerous phenomenons such as: accidents linked to climate or weather, nutritional disorders, phytotoxicity linked to treatment, genetic anomalies, or any other environmental factors or human interventions, ...
An abiotic vector is a non-living phenomenon able of successfully transporting a pathogen agent from an infected living organism to another healthy living organism or to its environment or its consummed resource. Transport is considered effective if it enables the pathogen agent to be maintained in the environment in question. In plant health, water and wind are two essential abiotic vectors involved in the spread of plant bioaggressors over varying distances (e.g. water/bacteria; wind/insect vectors).
Physical, chemical and other non-living environmental factors. They are essential for living plants and animals of an ecosystem, providing the essential elements and nutrients that are necessary for growth. The abiotic elements also include the climatic and pedologic components of the ecosystem.
A condition that varies between observation units, by taking different values or modalities, assessing the effect of which is the goal of the study. A factor may be biotic (pest, disease interaction) or abiotic (treatment, cultural practice) in nature. It must have at least two values or modalities.
All traits related to stress caused by non-living
stressors. Abiotic stress is defined as the
negative impact of non-living factors on the
crop/plants. Most common abiotic stressors are
drought, waterlogging, high/low temperatures,
mineral toxicities/deficiencies, hail, and wind.
Any toxin secreted by bacteria, viruses, fungi or protozoa enabling them to achieve colonisation of a niche in the host, inhibit or evade the host's immune response, enter and exit cells, or obtain nutrition from the host.
