TAPIR is a web server designed for the prediction of plant microRNA targets. The server offers the possibility to search for plant miRNA targets using a fast and a precise algorithm. The precise option is much slower but guarantees to find less perfectly paired miRNA - target duplexes. Furthermore, the precise option allows the prediction of target mimics, which are characterized by a miRNA - target duplex having a large loop, making them undetectable by traditional tools.
