Non-hydraulic signals from maize roots in drying soil: inhibition of leaf elongation but not stomatal conductance.

abstract：:Pea plants grown under different conditions of cultivation, and eight different plant species with variegated leaves were used to study the intracellular localization of shikimate oxidoreductase (EC 1.1.1.25), the marker enzyme of the pre-chorismate pathway. The two series of experiments indicated an intra-and an extr...
