zma-miR169c-5p: Zma-mir169c-5p is a candidate miRNA that has been reported to regulate the induced systemic resistance (ISR) activated by different Bacillus spp. [PMC9964586]. In a study using microarray and degradome sequencing, zma-mir169c-5p was identified as one of the five selected miRNAs, along with zma-miR393a-5p_L+1R-2, zma-miR164e-5p, PC-3p-73272_34, and PC-3p-169098_11 [PMC9697682]. The targets of zma-mir169c-5p were found to be nuclear factor Y (NY), auxin signaling F-box 2 (AFB2), NAC domain containing protein 80 (NAC), metacaspase 1 (AMC1), and thioredoxin family protein (Trx) [PMC9697682]. Zma-mir169c-5p belongs to the miR169 family and is part of a network with zma-miR169a-5p and zma-miR169i-5p that is associated with ISR [PMC6829523]. It was not selected as one of the candidate ISR-associated miRNAs along with zma-miR169a-5p, zma-miR395b-5p, and zma-mir395b-p [PMC6829523] [PMC8839143]. These four miRNAs were specifically repressed in FZB42 treatment and considered as potential ISR-associated miRNAs [PMC6829523] [PMC8839143]. In conclusion, zma-mir169c-p is a candidate miRNA that plays a role in regulating ISR in maize.
