In plants, most miRNAs are generated from independent transcriptional units, and only a few polycistronic miRNAs have been described.

Here, we show that a polycistronic miRNA comprising two miR family members, miRk and miRh, functions as a positive regulator of rice immunity. Rice plants with activated MIRkh expression showed enhanced resistance to infection by the fungal pathogens Magnaporthe oryzae and Fusarium fujikuroi, the causal agents of the rice blast and bakanae disease, respectively.

Disease resistance in rice plants with activated MIRkh expression was associated with a stronger expression of defense responses during pathogen infection. Stronger induction of MIRkh expression occurred in resistant but not susceptible rice cultivars.

Notably, the ethylene-insensitive 2 EIN2 gene was identified as a novel target gene for miRk. The regulatory role of the miRhk polycistron on the newly identified target gene results from the activity of the miRk-5p specie generated from the miRkh precursor.

Collectively, our findings support a role for miRk-5p in rice immunity by controlling EIN2 expression.

Because rice blast is one of the most destructive diseases of cultivated rice worldwide, unraveling miRkh-mediated mechanisms underlying blast resistance could ultimately help in designing appropriate strategies for rice protection. The crucial role of miRNAs in controlling plant developmental processes and response to abiotic stress is well documented De Lima et al.

Alterations in the accumulation of a substantial fraction of the miRNAome during pathogen cyclophilin a sequence for academic writing is also described in different pathosystems, and for some miRNAs a role in plant immunity has been described Shivaprasad et al.

However, our current knowledge of the biological roles of pathogen-regulated miRNAs in plant immunity is still limited, and most comes from studies in the interaction of Arabidopsis thaliana with the bacterial pathogen Pseudomonas syringae Staiger et al.

The spontaneous evolution from hairpin structures in the genome, or derivation from transposable elements, has also been proposed to explain the origin of plant miRNAs Felippes et al.

Whole-genome duplication events, and tandem or segmental duplications of MIR genes, are believed to be responsible for the expansion and diversification of miRNA gene families in plants Maher et al.

In animals, the occurrence of miRNA clusters is common, but only a few miRNA clusters have been described in plants, mainly in Arabidopsis Boualem et al. These clustered miRNAs can be transcribed independently or simultaneously as polycistronic transcripts. Furthermore, transcripts of polycistronic miRNAs might contain copies of members belonging to the same miRNA family homologous polycistronor unrelated miRNAs non-homologous polycistron.

The miR family comprises multiple members in monocotyledonous and dicotyledonous plants that are transcribed independently monocistrons. Altered accumulation of miR during abiotic stress also led to the notion that miR might play a role in the plant response to diverse abiotic stresses.

Very recently, it has been described that miR knockdown triggers drought resistance in rice Zhang et al. Evidence for miR in adapting to pathogen infection in plants has not been reported. Recently, we described the occurrence of a rice polycistronic miRNA, miRkh, comprising two miR family members miRk and miRh.

Expression profiling revealed that mature miRNAs generated from the miRkh precursor are co-expressed in rice leaves Baldrich et al. In other studies, various miR species were found to differentially respond to infection by the rice blast fungus M. In this work, we present evidence supporting that MIRkh plays a role in rice immunity.

We show that rice plants with activated MIRkh expression exhibit resistance to infection by the fungal pathogens M. Rice blast is one of the most devastating diseases of cultivated rice due to its widespread distribution and destructiveness Wilson and Talbot, The phenotype of disease resistance is associated with a stronger induction of defense responses during pathogen infection.

MIRhk expression was strongly induced by M. Moreover, we identified a novel target gene for miRk, the ethylene-insensitive 2 EIN2 gene targeted by miRk-5p in the miRkh polycistron. Overall, our results support that the polycistronic miRkh positively regulates rice immunity through modulation of EIN2 expression.

Rice seeds were pregerminated for 24 h on Murashige and Skoog MS medium and then inoculated with a suspension of F. Seedlings were allowed to continue germination for 1 week. Three independent infection experiments were performed, with at least 24 plants per genotype in each experiment.

For this, standard curves were prepared by using M. For elicitor treatment, 3-week-old plants were sprayed with an elicitor suspension of M.

Control plants were mock-inoculated. Primers were designed by using the Primer3 software 2.Instructor's Review Copy for A Sequence for Academic Writing, 6th Edition.
