General Information

General Information Comment Organism
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 Medicago truncatula
