a protein kinase-phosphatase pair, K-252a-insensitive protein kinase and Mg2+ -dependent type 2C protein phosphatase, co-localizes at least in part with the H+-ATPase in the plasma membrane and regulates the phosphorylation status of the penultimate threonine of the H+-ATPase |

| 7.1.2.1 | physiological function |
a TNt1 insertion mutant is impaired in the development of arbuscules but not in root colonization by Rhizophagus irregularis hyphae. Artificial microRNA silencing of HA1 results in small and truncated arbuscules. Unlike the wild type, the mutant fails to show a positive growth response to mycorrhizal colonization under phosphate-limiting conditions. Mutants are unable to take up phosphate via the mycorrhizal pathway. In the apoplast of abnormal arbuscule-containing cells of the mutant pH is increased. HA1 may be crucial for building a proton gradient across the periarbuscular membrane and indispensible for the transfer of phosphate from the fungus to the plant |

| 7.1.2.1 | physiological function |
H+-ATPase is a key enzyme of cell metabolism generating electrochemical proton gradient across the plasma membrane, thus playing an important role in the maintenance of ion homeostasis in the cell |

isoform AHA1 plays a major role in stomatal opening in response to blue light |

| 7.1.2.1 | physiological function |
plasma membrane activity largely increases in Ca2+-treated plants. Higher ATPase activity is related with apoplast acidification, cytosol alkalinization and low cytosolic [Na+], and may explain why extra calcium improves shoot and leaf growth |

| 7.1.2.1 | physiological function |
plasma membrane H+-ATPase AHA1 activity in transgenic plants lacking cytoplasmic immune receptor RPM1 is significantly lower than that in plants lacking cytoplasmic immune receptor RPM1 but expressing Pseudomonas syringae effector protein AvrB. AHA1 promotes the interaction between the jasmonate receptor CORONATINE INSENSITIVE1 and JASMONATE ZIM-DOMAIN proteins and enhances jasmonate signaling, which is required for optimum stomatal infection in AHA1-active plants. Pseudomonas syringae effector protein AvrB also induces the CORONATINE INSENSITIVE1 and JASMONATE ZIM-DOMAIN interaction and the degradation of multiple JASMONATE ZIM-DOMAIN proteins |

| 7.1.2.1 | physiological function |
plasma membrane H+-ATPases play a major role in the apoplastic acidification by H+ transport from cytosol to the apoplast |
