Morphological analysis, agronomic characteristics, species identification, and phylogenetic analysis of Pseuderanthemum sp. using the rbcLgene

Abstract

The study aimed to evaluate the agronomic characteristics of eleven samples of Pseuderanthemum sp. variety based on the results of the morphological survey on stem height, root length, leaves, combining molecular biology methods to determine their genetic relationships by building a phylogenetic tree based on the plastid gene rbcL sequence. Initial results of an evaluation of the genetic diversity of eleven Pseuderanthemum sp. samples showed that there were differences in stem length, leaf width to root length. Based on the analysis results from the pedigree tree, the tree samples with similar survival indexes and genetically close to each other were classified into two main groups. Based on molecular data, eleven varieties of Pseuderanthemum sp. in the study have been identified, all belonging to the species Pseuderanthemum sp. have a high similarity coefficient above 98% and 100% coverage. Although the geographical location of the samples is variable, it is necessary to investigate other gene sequences related to morphological and biochemical characteristics, such as bioactive compounds in leaves and fruits to have more accurate conclusions about this species.
