The effect of
Barley stripe mosaic virus
(BSMV) infection was studied on the ultrastructure of etioplasts and the greening process of barley (
cv. Pannónia) plants infected by seed transmission. The leaves of 7–11-day old etiolated seedlings were examined with transmission electron microscopy and absorption spectroscopy. The etioplasts of infected seedlings contained smaller prolamellar bodies with less regular membrane structure while prothylakoid content was higher than in the control. Characteristic effect was observed in the process of the Shibata-shift: 40 min delay was observed in the infected leaves. The results of this work proved that BSMV infection significantly delays or inhibits the plastid development and the formation of photosynthetic apparatus.
