osa-miR528-5p: Osa-mir528-5p is a mature miRNA that is up-regulated by Cd treatment [PMC7003353]. In a study of rice inflorescence small RNA libraries, a total of 183 mature miRNAs from 122 non-conserved families were identified [PMC5647096]. Among these miRNAs, over 156 had an expression level of TPM<10, 19 had TPM values between 10 and 100, and 7 had TPM values between 100 and 1000 [PMC5647096]. Interestingly, only osa-mir528-5p had a TPM value greater than 1000 [PMC5647096]. This suggests that osa-mir528-5p is highly expressed compared to other miRNAs in rice inflorescence. The up-regulation of osa-mir528-5p by Cd treatment indicates its potential role in response to cadmium stress [PMC7003353]. The specific function of osa-mir528-5p in this context is not mentioned in the given information. However, further research may provide insights into its role in the response to cadmium stress and its potential implications for rice plants.
