#Ammonium triggers formation of lateral roots
“#Ammonium triggers formation of lateral roots” Localized ammonium supply enhances the import and accumulation of shoot-derived auxin into the root vasculature, generating an auxin source for lateral auxin movement. AMT-dependent ammonium uptake stimulates proton release, leading to apoplastic acidification and protonation of auxin (IAA) to IAAH, which diffuses from the vasculature to outer root cells…
