PucciDB: A LTR-retrotransposon library of Pucciniales
<p>Rusts are fungi that infect plants, and specially, some important crops such as wheat and coffee. There are several rust genomes sequenced and release in databases like NCBI, but there is no deep studies in the dynamics and structures of transposable elements and in LTR-retrotransposons. Here, we created a lineage-level classified library of LTR-retrotransposons that can be used to annotate rust genomes (the complete-element version) or to classify elements detected in those genomes (using the domain version). We used 22 rust species to create this library.</p>
