Název v původním jazyce

Influence of spatial and temporal variations in the hypersensitive response on the accumulation of defense-related transcripts in powdery mildew-infected barley

Popis výsledku v původním jazyce

Effective race-specific resistance genes (R-genes) against Blumeria graminis f. sp. hordei (Bgh) in barley determine spatial and temporal variation of the hypersensitive response (FIR). This study investigated if different fast and slow acting FIR, mediated by Mla R-genes in barley will influence the expression of nine commonly induced defense-response genes at time points that coincide with Bgh penetration and hyphal formation. Mla1 resistance was characterized by a fast and significant increase in thedeath of single Bgh-attacked epidermal cells in response to Bgh isolate C15, whereas Mla3 resistance was characterized by a slow increase in mesophyll multiple cell death in response to Bgh isolate A6. The results from this study show that the differential expression of many Bgh-responsive defense genes in barley does not necessarily correlate with the spatial and temporal variations in FIR.
