| Abstract: | PROTEIN filaments are characteristic structural components of the assimilatory conducting elements of angiosperm plants (“P protein” of Cronshaw and Esau1). We have isolated filamentous structures from the phloem exudate of cut cucurbit stems2. The presence of the filaments could be clearly demonstrated after negative staining with the electron microscope. |
