osa-miR169r-3p: Osa-mir169r-3p is a member of the osa-miR169 family and is a downregulated miRNA in response to chilling stress in both 9311 and DC90 rice varieties [PMC9002458]. It is also downregulated in the phyB mutant [PMC4448008]. In one study, osa-mir169r-3p showed the most significant decrease in expression among differentially expressed miRNAs (DEMs) [PMC7076996]. Another study found that osa-mir169r-3p targets the ABC transporter encoded by LOC_Os11g07600, leading to its accumulation at high levels [PMC9597502]. Additionally, osa-mir169r-3p is one of the miRNAs that target OsHDZIP13, along with other miRNA families such as osa-miR414, osa-miR1429-3p, and osa-miR164d [PMC9405480]. These findings suggest that osa-mir169r-3p may play a role in phyB-mediated processes and senescence-associated regulation. However, further research is needed to fully understand its specific functions and regulatory mechanisms.
