MicroRNA molecules have been shown to play various significant roles in many physiological and pathophysiological processes in living organisms. The tremendous interest in these molecules has led to the significant development and constant release of a number of computational tools useful for basic as well as advanced miRNA-related analyses. These approaches have various constantly evolving utilities, such as detection, target prediction, functional annotation, and many others. In this chapter, we provide an overview of several computational tools useful for broadly defined plant miRNA analysis. We have added to the Tools4miRs new databases that provide extensive information on small noncoding RNA sequences. Additionally, several tools within the platform have been updated, now featuring comprehensive references and accessible links, ensuring users have access to the most recent and relevant research findings.
