Abstract
EM examination revealed the occurrence of virions in thin sections of developing ovules and embryo sacs of ''Atlas'' barley infected with a seed-transmitted strain of barley stripe mosaic virus, MI-1. The virus apparently invaded the primary meristem early, then infected the megaspore mother cell. In later stages of ovule development, the virus was seen in megaspores and in the cells of the embryo sac, including the egg. Virions were commonly associated with wall, cytoplasmic or spindle microtubules. By contrast, virions of the non-seed-transmittes strain of the virus (NSP) did not occur in developing ovules or embryo sacs. Ovule transmission was demonstrated only for MI-1.
