ITS sequence of native and alien Sagittaria species and their hybrids

Molecular validation of the putative hybrid seeds of Chinese native and alien Sagittaria species, using ITS sequence (ITS1, 5.8S rRNA, ITS2, partial and complete sequence). There are three crosses:Sagittaria trifolia X Sagittaria platyphylla, Sagittaria platyphylla X Sagittaria trifolia, and Sagittaria platyphylla X Sagittaria pygmaea.
