from the plant to the environment through transpiration and a simultaneous increase in stomatal density, which contributes to the balance of gas exchanges ( Batista et al., 2010 ). This property can compensate for the leaf area loss that is commonly

reduction in leaf expansion further reduces leaf area and transpirational water loss. These adjustments aid in acclimating the plant to prolonged periods of water stress. Loveys (1984) was one of the first to suggest that a xylem-located “signal
