Sarah Elizabeth Smith 1941–2019

Sally Smith (1941–2019) was a world leader in the study of arbuscular mycorrhizal symbioses between plants and soil fungi that allow a wide range of plants to grow in soils low in nutrients, especially phosphate (Fig. 1). Her work has been relevant to both plant ecology and agricultural productivity. Sally obtained a tenurable position at the University of Adelaide after many years’ employment on short-term contracts. She rapidly developed a large and active group that researched at scales ranging from advanced microscopy through molecular biology and physiology to plant ecology. Sally established long-standing international collaborations and was awarded many honours. She was a keen cook and gardener, and became an avid birdwatcher, travelling the world with her husband Andrew in pursuit of their hobby.
