ABSTRACT Pandan (Pandanus sp), Rotan (Calamus sp), and Rengas (Gluta sp) are the three most important plants growing at Kajuik Lake, Langgam, Riau Province, Indonesia; however, their species names have not been identified. This study aimed to identify their species names using nuclear internal transcribed spacer (ITS) and psbA-trnH intergenic spacer sequences. The method employed was DNA isolation from fresh leaves, PCR using primer pairs of ITS region for Pandanus sp and psbA-trnH intergenic spacer for Calamus sp and Gluta sp, electrophoresis, sequencing, and data analysis using BLASTn program and MEGA software version 6.0. Pandanus tectorius was the only one accession that was similar to Pandanus sp with the identity was 90%, however the query cover was... |
