Surveying in the locus, we extrapolated that the SLAC1 gene, which is associated with stomatal closure, was likely responsible for the difference of drought tolerance.
Title: Alteration of Arabidopsis SLAC1 promoter and its association with natural variation in drought tolerance.

SLAC1 is required for rapid stomatal closure in response to ozone, reduced air humidity and darkness.
Title: PYR/RCAR receptors contribute to ozone-, reduced air humidity-, darkness-, and CO2-induced stomatal regulation.

Guard cells with mutations in slac1 exhibit dramatically reduced inwardly-rectifying K+ channel currents. Decreasing the cytosolic Ca2+ concentration rapidly restores K+ channel currents in slac1 guard cells.
Title: Mutations in the SLAC1 anion channel slow stomatal opening and severely reduce K+ uptake channel activity via enhanced cytosolic [Ca2+] and increased Ca2+ sensitivity of K+ uptake channels.

The predictive power of a systems dynamic model in Arabidopsis, is demonstrated to explain the paradoxical suppression of channels that facilitate K(+) uptake, slowing stomatal opening, by mutation of the SLAC1 anion channel.
Title: Systems dynamic modeling of a guard cell Cl- channel mutant uncovers an emergent homeostatic network regulating stomatal transpiration.

Data suggest that SLAC1 may be a pathway providing CO(2) for photosynthesis in the guard cells.
