Polar localization of a symbiosis-specific phosphate transporter is mediated by a transient reorientation of secretion.

Proceedings of the National Academy of Sciences of the United States of America - 13 Mar 2012

Pumplin Nathan, Zhang Xinchun, Noar Roslyn D, Harrison Maria J

Abstract excerpt

The arbuscular mycorrhizal (AM) symbiosis, formed by land plants and AM fungi, evolved an estimated 400 million years ago and has been maintained in angiosperms, gymnosperms, pteridophytes, and some bryophytes as a strategy for enhancing phosphate acquisition. During AM symbiosis, the AM fungus colonizes the root cortical cells where it forms branched hyphae called arbuscules that function in nutrient exchange...
