Implication

Experimental study demonstrates stomatal closure and stable leaf water potential in waterlogged tomato plants, indicating root-mediated regulation independent of direct ACC action.

Key Points

Investigate the impact of soil flooding on stomatal conductance, transpiration, root water transport, and leaf movement in tomato plants.
Measured leaf water potential, epidermal conductance, transpiration, and root hydraulic conductance in waterlogged Lycopersicon esculentum plants.
Performed root excision, stem girdling, and chemical evaluations of 1-aminocyclopropane-1-carboxylic acid (ACC) translocation to assess root-shoot communication.
Soil waterlogging reduced stomatal conductance and transpiration by 30% to 40% after approximately 24 hours.
Leaf water potential remained unchanged despite a marked decrease in root hydraulic conductance.
Root-derived ACC showed no direct effect on stomatal conductance, though ethylene-induced petiole epinasty developed concurrently with stomatal closure.
