Summary Largely because of concerns regarding global climate change, there is a burgeoning interest in the application of fundamental scientific knowledge in order to better exploit environmental cues in the achievement of desirable endpoints in crop production. Ultraviolet ( UV ) radiation is an energetic driver of a diverse range of plant responses and, despite historical concerns regarding the damaging consequences of UV ‐ B radiation for global plant productivity as related to stratospheric ozone depletion, current developments representative of a range of organizational scales suggest that key plant responses to UV ‐ B radiation may be exploitable in the context of a sustainable contribution towards the strengthening of global crop production, including alterations in secondary metabolism, enhanced photoprotection, up‐regulation of the antioxidative response and modified resistance to pest and disease attack. Here, we discuss the prospect of this paradigm shift in photobiology, and consider the linkages between fundamental plant biology and crop‐level outcomes that can be applied to the plant UV ‐ B response, in addition to the consequences for related biota and many other facets of agro‐ecosystem processes.ContentsSummary 1058 I.
