Leaf hydraulic maze; Differential effect of ABA on vascular bundle-sheath, palisade, and spongy mesophyll controlling hydraulic conductance
A. Yaaran, E. Erez, C. Procko, M. Moshelion
This study investigates how ABA affects hydraulic conductance in different leaf cell types, finding that ABA-insensitive spongy mesophyll cells have reduced water permeability and that the bundle sheath-spongy mesophyll pathway regulates leaf water-use efficiency.
