Plasmatubules are tubular evaginations of the plasmalemma. They have previously been found at sites where high solute flux between apoplast and symplast occurs for a short period and where wall proliferations of the transfer cell type have not been developed (Harris et al. 1982, Planta 156, 461–465). In this paper we describe the distribution of plasmatubules in transfer cells of the leaf minor veins of Pisum sativum L. Transfer cells are found in these veins associated both with phloem sieve elements and with xylem vessels. Plasmatubules were found, in both types of transfer cell and it is suggested that the specific distribution of the plasmatubules may reflect further membrane amplification within the transfer cell for uptake of solute from apoplast into symplast.
