Holmes-ITS2 Database

DNA barcode

A standardized short sequence of DNA from a small region of an organism's genome that can differentiate the species from others.

For plants, the chosen and validated sequences include ITS2, matK, rbcL, psbA-trnH etc. for the identification of plant species.


The current ITS2 dataset contains 157,937 processed entries of plant ITS2 sequences including:
2 phyla
38 classes
169 orders
501 families
8,385 genera
65,281 species


A taxonomy classification platform based on multiple DNA biomarkers and search engines hosted at NingLab@HUST
