Manganese triggers phosphorylation-mediated endocytosis of the Arabidopsis metal transporter NRAMP1.

The Plant journal : for cell and molecular biology - 1 Jun 2021

Castaings Loren, Alcon Carine, Kosuth Thibault, Correia David, Curie Catherine

Abstract excerpt

The NATURAL RESISTANCE-ASSOCIATED MACROPHAGE PROTEIN 1 (NRAMP1) transporter guarantees plant survival of manganese (Mn) deficiency by mediating Mn entry into root cells. Unlike other high-affinity metal transporters, NRAMP1 is only slightly regulated at the transcriptional level. We show here that adequate Mn content in tissues is safeguarded through a tight control of the quantity of NRAMP1 present at the...
