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:
