Abstract
Summary Studies of lead distribution in juvenile roots of Raphanus sativus using light and electron microscopy have revealed that in developing root steles specific accumulation of lead occurs in the protophloem cells. This accumulation appears to be attributable at least in part, to an inability of the endodermis to exclude lead from the vicinity of such phloem cells. Electron microprobe analyses support this hypothesis, and the observed distributions of lead are discussed in relation to phloem and root-tip structure and function.
