mtr-miR156b-5p: mtr-mir156b-5p is a microRNA that exhibits opposite expression profiles during certain conditions [PMC8369265]. In a study, it was found that miR156a/b, including gma-miR156a and mtr-mir156b-5p, targeted SBP14 and up-regulated its expression under salt stress, suggesting that the miR156a/b-SBP14 module enhances salt tolerance by increasing ROS scavenging [PMC9011107]. Additionally, ginseng targets genes in the plant hormone signal transduction pathway through ptc-miR156k_L+1, mtr-mir156b-5p, gma-miR156a_R+1, and mtr-miR156e, leading to the inhibition of gene expression in the hormone synthesis pathway [PMC9659575]. Through a joint analysis with mRNA sequencing data, it was found that TRINITY_DN14567_c0_g4 is the target gene of ptc-miR156k_L+1, mtr-mir156b-5p, gma-miR156a_R+1, and mtr-miR156e in the plant hormone signal transduction pathway [PMC9659575]. Furthermore, all four miRNAs were negatively correlated with mRNA expression levels, suggesting their involvement in regulating disorders related to continuous cropping of ginseng and the synthesis of ginsenosides [PMC9659575].
