plant stress response trait abiotic plant stress response trait abiotic stress tolerance (related) Plant abiotic stress traits may be manifested in either the whole plant (PO:0000003) or in parts of the plant, as a result of the exposure to an abiotic plant stress (PSO:0000012). Responses to plant stresses may vary from resistance to susceptibility, with varying levels of tolerance. Abiotic stresses are those resulting from non-living factors such as drought, salinity or temperature extremes.
