DISTINCTION BETWEEN CRINUM LATIFOLIUM AND CRINUM ASIATICUM (AMARYLLIDACEAE) USING MOLECULAR DATA

Abstract

Crinum latifolium and C. asiaticum are the two species of genus Crinum, Amaryllidaceae family and they have highly medicinal values. Distinction between two species is challenging due to many similar morphological characteristics. In this study, we used molecular makers to distinguish the two species Crinum latifolium and C. asiaticum. The phylogenetic tree was constructed based on the DNA sequence data of the ITS (internal transcribed spacer) nuclear ribosomal DNA (nrDNA) sequences of Crinum latifolium and C. asiaticum. As a result, C. latifolium and C. asiaticum were sorted into two different groups in the phylogenetic tree. Therefore, C. latifolium and C. asiaticum were carried out to solve the taxonomic ambiguity.
