Electron microscopy of artichoke mottled crinkle virus in leaves of Chenopodium quinoa Willd.

The ultrastructure of mesophyll cells of Chenopodium quinoa Willd. infected with artichoke mottled crinkle virus (AMCV) was investigated with the electron microscope. The cytoplasm of altered cells contained complex multivesicular bodies orginating from arrangement of endoplasmic reticulum membranes, small vesicles, and electron opaque granular material into a pseudo-organellar form. Structural modifications of chloroplasts but not of mitochondria were noticed. The nuclei exhibited prominent membranous inclusions and contained a few virus particles. AMCV particles were occasionally associated with chloroplasts and were plentiful in the cytoplasm, where they occurred in a loosely disperse fashion or in crystalline aggregates. Virions were found also in the central vacuole either free or in vesicular cytoplasmic extrusions.

Ultrastructural observations on the mesophyll cells of pine leaves

The ultrastructure of mesophyll cells of Pinus strobus has been investigated in the spring and winter months. Wall invaginations begin in the early spring and eventually give the cells a lobed appearance. The chloroplasts are of the normal stroma lamella – grana type and completely ring the cells by winter. Lipid globules and electron-dense phenol deposits increase in the winter months.
