An application of genetics-chemicals constituents to the relatedness of three Euphorbia species

Abstract

Genetics and chemicals relatedness among three Euphorbia species (Euphorbia prostrata Aiton, Euphorbia peplus L. and Euphorbia terracina L.) were analysed by RAPD, ISSR markers and GC-MS technique. RAPD profiling pattern revealed that E. peplus and E. terracina in one cluster with similarity value (44.37%) while the lowest value (29.14%) between E. prostrata and E. terracina. ISSR profiling pattern revealed that E. prostrata and E. terracina in one cluster with similarity value (46.75%) and the lowest similarity value (37.87%) between E. prostrata and E.peplus. The sum results of RAPD and ISSR data revealed that E. peplus and E. terracina in one cluster with similarity value (44.69%) while the lowest value (36.88%) between E. prostrata and E. peplus. Sixty-eight chemicals pattern revealed that E. prostrata and E. peplus in one cluster with similarity value (39.71%) while the lowest value (25.0%) between E. prostrata and E. terracina. Super tree (RAPD, ISSR and phytocomponents) revealed that E. peplus and E. terracina in one cluster with similarity value (43.04%) while the lowest value (36.08%) between E. terracina and E. prostrata. In conclusion, biosystematics tools including biomarkers and chemical compounds can be applied to investigate relatedness of Euphorbia species and probably to other plant taxa.
