Putrescine and Acid Stress [PDF]
Plant Physiology, 1983 Incubation of peeled oat Avena sativa L. var Victory leaf segments on media of pH 5.0 or below leads to a rapid and massive increase in the titer of putrescine while incubation at pH values above 5.0 causes little or no change. The low pH effect is independent of the buffer system employed.

The Smell of Death: Evidence that Putrescine Elicits Threat Management Mechanisms
Frontiers in Psychology, 2015 The ability to detect and respond to chemosensory threat cues in the environment plays a vital role in survival across species. However, little is known about which chemical compounds can act as olfactory threat signals in humans.
