Descrição: Recent results suggest that metabolism‐mediated stomatal closure mechanisms are important to regulate differentially the stomatal speediness between ferns and angiosperms. However, evidence directly linking mesophyll metabolism and the slower stomatal conductance (gs) in ferns is missing. Here, we investigated the effect of exogenous application of abscisic acid (ABA), sucrose and mannitol on stomatal kinetics and carried out a metabolic fingerprinting analysis of ferns and angiosperms leaves harvested throughout a diel course. Fern stomata did not respond to ABA in the time period analysed. No differences in the relative decrease in gs was observed between ferns and the angiosperm following provision of sucrose or mannitol. However, ferns have slower gs responses to these compounds than angiosperms. Metabolomics analysis highlights that ferns have a higher accumulation of secondary rather than primary metabolites throughout the diel course, with the opposite being observed in angiosperms. Our results indicate that metabolism‐mediated stomatal closure mechanisms underpin the differential stomatal speediness regulation among ferns and angiosperms, in which the slower stomatal closure in ferns is associated with the lack of ABA‐responsiveness, to a reduced capacity to respond to mesophyll‐derived sucrose and to a higher carbon allocation toward secondary metabolism, which likely modulates both photosynthesis‐gs and growth‐stress tolerance trade‐offs. Summary Statement The slower stomatal closure in ferns is associated to the lack of abscisic acid‐responsiveness, to a reduced capacity to respond to mesophyll‐derived sucrose and to a higher carbon allocation toward secondary metabolism, as compared to angiosperms.
