sly-miR396a-3p: Sly-mir396a-3p is a down-regulated miRNA in the M82 tomato variety but is up-regulated in the IL9-1 variety [PMC5485680]. It is one of the nine miRNAs that are down-regulated in M82 and up-regulated in IL9-1 [PMC5485680]. Sly-mir396a-3p is also one of the seven conserved miRNAs and three novel miRNAs that were selected for validation [PMC5485680]. In another study, sly-mir396a-3p was found to be down-regulated in M82 but up-regulated in IL9-1, along with sly-miR166c-5p [PMC8258350]. Sly-mir396a-3p was also identified as one of the miRNAs targeting polyamine transporter genes in tomato, specifically targeting Put7 and Put8 genes [PMC9952195]. In a comparison of two stresses, sly-mir396a-3p was found to be down-regulated while eight other miRNAs were up-regulated [PMC5499734]. Overall, sly-mir396a-3p shows differential regulation between tomato varieties and under different stress conditions.
