title: Evidence for the cytoplasmic localization of betaine in leaf cells of Suaeda maritima.
abstract: An attempt has been made to localize glycinebetaine in shoots of Suaeda maritima L. Dum. using a technique based on the formation of an iodoplatinate precipitate. Deposits were largely restricted to the cytoplasm of salt-grown plants and were analysed by transmission analytical electron microscopy. The results are considered to support the hypothesis that glycinebetaine acts as a cytoplasmic osmoticum to balance high vacuolar salt levels in certain halophytes.
