Phosphosite charge rather than shootward localization determines OCTOPUS activity in root protophloem.

Proceedings of the National Academy of Sciences of the United States of America - 11 Jul 2017

Breda Alice S, Hazak Ora, Hardtke Christian S

Abstract excerpt

Polar cellular localization of proteins is often associated with their function and activity. In plants, relatively few polar-localized factors have been described. Among them, the plasma membrane-associated Arabidopsis proteins OCTOPUS (OPS) and BREVIS RADIX (BRX) display shootward and rootward polar localization, respectively, in developing root protophloem cells. Both ops and brx null mutants exhibit defects...
