Diversity of Gyrinops versteegii from several agarwood plantation on Lombok Island (Indonesia) as raw material of Gyrinops tea

Abstract

Abstract. Wangiyana IGAS, Supriadi, Nikmatullah A, Sunarpi, Triandini IGAAH. 2021. Diversity of Gyrinops versteegii from several agarwood plantation on Lombok Island (Indonesia) as raw material of Gyrinops tea. Biodiversitas 23: 178-186. The purpose of this research is to examine the diversity of Gyrinops versteegii as a raw material of agarwood Gyrinops tea based on morphology, phytochemical, and molecular characters. G. versteegii samples were taken from 5 agarwood plantation on Lombok Island: Lingsar, Rarung, Mataram, Kekait, and Pejaring. Variation of G. versteegii stem, leaves, and fruit was the morphology character observed in this study. Qualitative phytochemical screening, quantitative tannin concentration, and the hedonic score of Gyrinops tea were the essential phytochemical character in this study. DNA fingerprinting and RAPD analysis were the molecular characters of this study. All of those characters were used in numeric-phenetics analysis to construct a dendrogram. MVSP program with UPGMA algorithm as clustering method and Simple Matching Coefficient for similarity analysis was used to construct dendrogram. The result has shown variation topology of dendrogram based on morphology, phytochemical, molecular, and combination character. However, all dendrograms had the same number of clusters and cluster members. G. versteegii kekait and G. versteegii Pejaring were grouped to cluster 1 while G. versteegii Rarung and G. versteegii Mataram were grouped to cluster 2. G. versteegii Lingsar was grouped later on the node after cluster 1 or 2. It could be concluded that G. versteegii from Lombok Island Plantation could be divided into three different cluster groups based on the variation of morphology, chemical, and molecular characters.

Antibacterial and phytochemical constituent of Etlingera rubroloba A.D. Poulsen extract, an endemic ginger from Wallacea Region, Indonesia

“…Barra (2009) explains that variations in secondary metabolite content in a plant species are influenced by three factors, namely (i) intraspecies genetic variation (ii) differences in plant organs and in the stages of plant organs development, (iii) differences in environmental factor. The effect of genetic variation within a species is in line with research conducted by Asensio et al (2020) and Wangiyana et al (2022). Asensio et al (2020) revealed that genetic and cytogenetic diversity (eg polyploidization) significantly affected the variations of phytochemical content in Bearberry.…”

“…Asensio et al (2020) revealed that genetic and cytogenetic diversity (eg polyploidization) significantly affected the variations of phytochemical content in Bearberry. While Wangiyana et al (2022) reported that Molecular (genetic) variations in Gyrinops versteegii (Gilg.) Domke (Gyrinops tea) correlated with variations in phytochemical content and morphological variations between accessions.…”

Revealing the genetic diversity of Sumbawa endemic horse using microsatellite-based DNA fingerprint

“…These bands were treated as DNA fingerprinting characters for similarity value calculation. Similarity value was essential for clustering analysis for dendrogram construction (Wangiyana et al 2022). This systematic step has been used recently for genetic diversity studies based on microsatellite DNA fingerprinting (Driskill et al 2022;Fiore et al 2022).…”

Estimating the Genetic Diversity of Oranges Citrus spp. in South Sulawesi, Indonesia, Using RAPD Markers

“…RAPD markers can be recommended for use in Citrus breeding programs. To date, RAPD is still widely used to assess genetic diversity in various plant species [8,10,[32][33][34][35][36]. In Citrus plants, RAPD markers have been used for cultivar identifcation, mapping, genetic diversity assessment, and other breeding programs [37].…”
