sly-miR164a-5p: Sly-mir164a-5p is a microRNA that was found to be down-regulated under treatment with Tomato chlorotic virus (ToCV) [PMC8258350]. In M82, sly-mir164a-5p was identified as a potential regulator of Lnc_000929, Lnc_000976, and Lnc_000530 [PMC9295719]. Additionally, sly-mir164a-5p was found to target genes encoding SPL, NAC, MYB, GRAS, and TCP transcription factors that are associated with plant stress tolerance [PMC5485680]. In tomato plants, a total of 29 miRNAs were identified to target polyamine transporter genes. Among them were sly-miR390a-5p, sly-miR390b-5p, and sly-miR6022 targeting Put1; sly-miR6024 and sly-miR6026 targeting Put2; sly-miR6023 and sly-miR1916 targeting Put3; and several miRNAs targeting Put4 (sly-miR9479-3p, sly-miR6024, sly-miR171c, etc.) [PMC9952195]. Furthermore, the interaction of sly-mir164a-5p with lncRNA XR_002027860.1 and mRNA XM_010327149.2 was observed [PMC6336255]. These findings highlight the potential role of sylmir164a-5p in regulating gene expression in tomato plants under various conditions.
