Background: Bacterial wilt is the most devastating disease in ginger caused by Ralstonia solanacearum. Even though ginger (Zingiber ofcinale) and mango ginger (Curcuma amada) are from the same family Zingiberaceae, the latter is resistant to R. solanacearum infection. MicroRNAs have been identifed in many crops which regulates plant-pathogen interaction, either through silencing genes or by blocking mRNA translation. However, miRNA’s vital role and its targets in mango ginger in protecting bacterial wilt is not yet studied extensively. In the present study, using the “psRNATarget” server, we analyzed available ginger (susceptible) and mango ginger (resistant) transcriptome to delineate and compare the microRNAs (miRNA) and their target genes (miRTGs).
Results: A total of 4736 and 4485 diferential expressed miRTGs (DEmiRTGs) were identifed in ginger and mango ginger, respectively, in response to R. solanacearum. Functional annotation results showed that mango ginger had higher enrichment than ginger in top enriched GO terms. Among the DEmiRTGs, 2105 were common in ginger and mango ginger. However, 2337 miRTGs were expressed only in mango ginger which includes 62 defence related and upregulated miRTGs. We also identifed 213 miRTGs upregulated in mango ginger but downregulated in ginger, out of which 23 DEmiRTGS were defence response related. We selected nine miRNA/miRTGs pairs from the data set of common miRTGs of ginger and mango ginger and validated using qPCR. Conclusions: Our data covered the expression information of 9221 miRTGs. We identifed nine miRNA/miRTGs key candidate pairs in response to R. solanacearum infection in ginger. This is the frst report of the integrated analysis of miRTGs and miRNAs in response to R. solanacearum infection among ginger species. This study is expected to deliver several insights in understanding the miRNA regulatory network in ginger and mango ginger response to bacterial wilt.
