This study presents six universal primers for amplifying three non-coding regions of chloroplast DNA (cpDNA) using the polymerase chain reaction (PCR). These primers were tested on various plant species, including algae, bryophytes, pteridophytes, gymnosperms, and angiosperms, and worked for most of them. The primers target conserved regions flanking more variable regions, increasing the likelihood of successful amplification across a wide taxonomic range. The primers were designed based on complete cpDNA sequences from tobacco, marchantia, and rice, and were optimized to avoid palindromic sequences and potential hybridization with nuclear and mitochondrial tRNA genes. The primers were tested on various plant species, and the results showed that they can be used for studying population biology and evolution. The study also describes the sequences of the six primers and their application in amplifying three non-coding regions of cpDNA. The primers were used to amplify DNA from various plant species, and the results showed that they can be used for RFLP analysis. The study also includes figures showing the positions and directions of the primers, the expected sizes of PCR products, and the variation in size of the trnL (UAA) intron among different plant species. The results indicate that these primers are universal and can be used for studying the genetic diversity and evolution of plants.This study presents six universal primers for amplifying three non-coding regions of chloroplast DNA (cpDNA) using the polymerase chain reaction (PCR).
