title: Banded filaments associated with the aster yellows MLO in Vinca rosea L.
abstract: The ultrastructure of an aster yellows mycoplasma-like organism was studied in the phloem of periwinkle (Vinca rosea L.) plants. Banded filaments were observed in association with mycoplasma-like organisms of characteristic morphology. The filaments were variable in length, from 50-100 nm in width, and displayed a regular periodic banding of alternating electron-dense and electron-lucent structures.
