Plant responses to heat stress | Desert Botanical Garden


Water loss in plants has commonly been considered only as a cost of photosynthetic carbon gain. However, plants may use water in ways that may not necessarily optimize instantaneous carbon gain, but instead as a strategy for leaf evaporative cooling. The DPEL and collaborators aim to assess whether plant water use is not always a side-effect of carbon gain, but rather an active strategy to optimize leaf temperature to cope with thermal stress that is becoming more common with climate change.
