The plant miRNA database (PMRD) integrates available plant miRNA data deposited in public databases, gleaned from the recent literature, and data generated by the database organizers. This database contains sequence information, secondary structure, target genes, expression profiles and a genome browser.
In total, there are 8433 miRNAs collected from 121 plant species in PMRD, including model plants and major crops such as Arabidopsis, rice, wheat, soybean, maize, sorghum, barley, etc. For Arabidopsis, rice, poplar, soybean, cotton, medicago and maize, the possible target genes for each miRNA with a predicted interaction site are included in the database. In addition, some miRNA expression profiles are provided in the PMRD.
The PMRD is freely available at http://bioinformatics.cau.edu.cn/PMRD.
