bookmark PNRD / Plant Non-coding RNA Database forum (1) It is the updated version of PMRD. PNRD mainly focuses on plant species. A total of 25739 entries of 11 different types of ncRNAs from 150 plant species were collected. Targets of miRNAs were extended to 178138 pairs in 46 species, while the number of miRNA expression profiles reached 35. Improvements in PNRD are not only the larger amounts of data, but also better service, such as a more user-friendly interface, more multifunctional and browsing options and more background data for users to download.
