Additionally, CPK-mediated phosphorylation of MIZ1 relieved its inhibitory effect on the activity of the endoplasmic reticulum鈥搇ocalized Ca 2+ pump ECA1, altering the balance between cytoplasmic Ca 2+ inflow and outflow, thereby negatively regulating the hydrotropic growth of plants. Overall, our...
Expression of a pMIZ1:: GUS fusion gene at the tip of lateral roots and assessment of lateral root hydrotropism in the ahydrotropic mutant miz1, which did not display hydrotropism, demonstrated that the lateral roots of Arabidopsis have the capacity to respond to water potential gradients, and...
