By the closure of these pores, plants can limit transpiration and thus prevent excessive loss of water to the atmosphere. By contrast, the opening of stomata is required to enable uptake of CO2 for photosynthesis. Plants have evolved at least two regulatory mechanisms that couple stomatal opening to the demand for water and CO2. However, it is debated whether the ability to sense CO2 and humidity developed early in evolution, or if stomata gained these properties progressively. A study conducted by Franks & Britton-Harper, published in this issue of the New Phytologist (pp. 819–827), shows that CO2-sensing occurs in stomata of three evolutionary-distant fern species, thus favoring the hypothesis that stomatal responses to CO2 developed before seed plants separated from ferns c. 300 million years ago.
