Impact of viral infection on susceptible host includes a variety of responses affecting structural aspects, physiological and genetic processes. Using qRT-PCR, it was established quantitative deviations in expression levels of some genes in leaves of barley seedlings obtained from plants infected with barley stripe mosaic virus. The activity of genes studied in the present experiment was clearly influenced by viral infection. In barley progenies obtained from virus infected plants the expression of genes involved in antioxidant metabolism (Apx and Sod) was decreased in most variants. The relative expression of genes for pathogenesis-related proteins was significantly (P<0,05) modified in evaluated barley cultivars (Galactic, Sonor and Unirea). The obtained data showed up- or down- regulation of PR3 and PR10 in dependence of genotype, whereas for PR5 was reported only the up-regulation effects for all treated variants. 33 references, 2 tables, 1 figures. |
