Abstract:
:Brassica oleracea var. capitata (cabbage) is an economically important crop affected by black rot disease caused by Xanthomonas campestris pv. campestris (Xcc). MicroRNAs (miRNAs) play an important role in plant defense modulation and therefore the analysis of these molecules can help better understand plant-pathogen interactions. In this study, we report the differential expression of four miRNAs that seem to participate in the plant response to Xcc infection. Northern Blot and RT-qPCR techniques were used to measure miRNA expression in resistant (União) and susceptible (Kenzan) cultivars. From 6 miRNAs analyzed, 4 were detected and differentially expressed, showing a down- and upregulated expression profile in susceptible and resistant cultivars, respectively. These results suggest that miR156, miR167, miR169, and miR390 could play a role in B. oleracea resistance enhancement against Xcc and could be explored as potential resistance markers in B. oleracea-Xcc interaction.
