Abstract

•Arabidopsis NAD kinase2 (NADK2) positively regulates abscisic acid (ABA)-mediated stomatal movement.•NADK2 is required for ABA-stimulated increase in H2O2, Ca2+ and nitric oxide in guard cells.•ABA upregulates the expression of AtrbohD, AtrbohF and NIA1 depending upon NADK2 in guard cells.
