A tale of two pumps: Blue light and ABA alter Arabidopsis leaf hydraulics via bundle sheath cells H+-pumps and channels

T. Torne-Srivastava, Y. Grunwald, M. Rosenwald, A. Dalal, A. Yaaran, V. Schebtaev, M. Moshelion, N. Moran

This study investigates how blue light and ABA regulate leaf hydraulic conductance in Arabidopsis by modulating H+-pumps and channels in bundle sheath cells.

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.

Stress is basic: ABA alkalinizes both the xylem sap and the cytosol of Arabidopsis vascular bundle sheath cellsby inhibiting their P-type H+-ATPaseand stimulating their V-type H+-ATPase

T. Torne, Y. Grunwald, A. Dalal, A. Yaaran, M. Moshelion, N. Moran

This study shows ABA alkalinizes xylem sap and cytosol in Arabidopsis BSCs by inhibiting AHA2 and stimulating VHA, affecting pH balance and drought response.

Arabidopsis leaf hydraulic conductance is regulated by xylem-sap pH, controlled, in turn, by a P-type H+-ATPase of vascular bundle sheath cells

Y. Grunwald, N. Wigoda, A. Yaaran, N. Sade, T. Torne, S. C. Gosa, N. Moran, M. Moshelion

The paper shows that AHA2 in vascular bundle sheath cells regulates xylem sap pH, which in turn controls leaf hydraulic conductance.

Role of guard-cell ABA in determining maximal stomatal aperture and prompt vapor-pressure-deficit response

A. Yaaran, B. Negin, M. Moshelion

This study investigates the role of guard-cell ABA in stomatal responses to vapor pressure deficit, finding it does not drive immediate closure but is essential for adaptation to ambient VPD.
