Phylogenetic reconstruction of tree species on the University of North Sumatra Campus, based on the rbcL gene

A phylogenetic tree is an arrangement that can describe kinship data in the form of a branched tree. In the field of forestry, identification using morphological data is difficult because it takes a long time and the fruit and flower seasons are uncertain. Another alternative that can be used to create a phylogenetic tree is to use secondary data. This study aims to explore the availability of GeneBank sequence data for tree species at the Universitas Sumatera Utara and create a phylogenetic tree to see their relationships based on rbcL markers. The results showed that the highest sequence of trees on the USU campus using the rbcL gene was 86.8%. In the reconstruction of the phylogeny tree, the boostrap value is above 70%, and tree species are grouped according to the same family.
