The results also show that those three locations can be amplified by directional PCR. In addition, the nucleotide differences among those DNA regions of the two Camellia species ranged from 0% to suggesting the Camellia chrysantha (Ba Che, Quang Ninh) is a derivative of Camellia euphlebia (Son Dong, Bac Giang). | Testing three proposed DNA regions (matK, rbcL and ITS2) for identification of camellia euphlebia and camellia chrysantha
