osa-miR166d-5p: A study identified 15 differentially expressed miRNAs and their target genes, including osa-mir166d-5p, in non-infected and infected treatments at different stages [PMC9222952]. The expression of osa-mir166d-5p was found to be decreased in the LDS and REC root of N22, as well as in the SDS and REC root of N22 [PMC5447883]. Several miRNAs, including osa-mir166d-5p, have been suggested to be regulated under abiotic or biotic stresses [PMC4723043]. In infected plants, osa-mir166d-5p was found to be up-regulated and more abundant compared to healthy plants [PMC4723043]. The expression of osa-mir166d-5p was inhibited during heat treatment in the tolerant variety Nagina 22 [PMC7709044]. Both osa-mir166d-5p and another miRNA called osa-miR2097-3p were found to be involved in plant resistance to viruses [PMC7709044]. In response to rice stripe virus infection, the expression of osa-mir166d-5p increased significantly [PMC7709044]. Additionally, the Fold Change of osa-mir166d-5p was less than -4 upon infection with rice stripe virus [PMC4628322]. In susceptible plants infected with rice stripe virus, 20 miRNAs including osa-mir166d-5p were upregulated [PMC5897953].\
