athisomiRDB

Plant miRNAs are essential post-transcriptional regulators of gene expression. Small RNA sequencing has revealed substantial sequence and length variation among mature miRNAs, giving rise to isomiRs through alternative processing and post-transcriptional modifications.

Systematic isomiR-level annotation is critical for understanding the Arabidopsis miRNAome. athisomiRDB integrates isomiR sequence, expression, genomic, genetic, and functional information to support comprehensive exploration of isomiR diversity.
