Abiotic stress is the negative impact of non-living factors on the living organisms in a specific environment. The non-living variable must influence the environment beyond its normal range of variation to adversely affect the population performance or individual physiology of the organism in a significant way.

Biotic and abiotic stress tolerance in plants
Transcription factor polynucleotides and polypeptides incorporated into nucleic acid constructs, including expression vectors, have been introduced into plants and were ectopically expressed. Transgenic plants transformed with many of these constructs have been shown to be more resistant to disease (in some cases, to more than one pathogen), or more tolerant to an abiotic stress (in some cases, to more than one abiotic stress). The abiotic stress may include, for example, salt, hyperosmotic stress, water deficit, heat, cold, drought, or low nutrient conditions.
