While sorghum is drought-tolerant, the crop’s precise response is dependent on when exactly water becomes a limiting factor – before or after flowering. Reported in PNAS the week of December 2, 2019, is the first paper that describes sorghum’s response to drought, from a large-scale field experiment led by a multi-institutional consortium to uncover the mechanisms behind sorghum’s capacity to produce high yields despite drought conditions.
