The immortelle ( (Roth) G. Don) is a typical perennial plant of natural vegetation in the Mediterranean region, and due to secondary metabolites with several biological properties (anti-inflammatory, antioxidant, antimicrobial, and anti-proliferative), it has become an important species for essential oil production, especially in the cosmetic industry. To increase the production of highly priced essential oils, it has been moved to cultivated fields. However, due to the lack of highly characterized planting material, there is a great need for genotype identification, and to provide a link with chemical profiles and geographic origin as a basis for the identification of local superior genotypes. The aims of the study were to characterize the ITS (ribosomal internal transcribed spacer) regions, ITS1 and ITS2, in samples from the East Adriatic region to determine the possibility of using these regions for plant genetic resources identification. Genetic variation was observed when comparing the ITS sequence variants of samples from the North-East Adriatic and the South-East Adriatic. Some rare and unique ITS sequence variants can be helpful for identifying specific populations from different geographical regions.
蜡菊（（Roth）G. Don）是地中海地区天然植被中一种典型的多年生植物，由于具有几种生物特性（抗炎、抗氧化、抗菌和抗增殖）的次生代谢物，它已成为生产精油的重要物种，特别是在化妆品行业。为了增加高价位精油的产量，它已被移植到种植区。然而，由于缺乏高度特征化的种植材料，因此非常需要对基因型进行鉴定，并提供与化学特征和地理起源相关的联系，作为识别当地优良基因型的基础。本研究的目的是对来自东亚得里亚海地区的样本中的 ITS（核糖体内部转录间隔区）区域、ITS1 和 ITS2 进行特征描述，以确定这些区域是否可用于植物遗传资源鉴定。通过比较东北亚得里亚海和东南亚得里亚海样本的 ITS 序列变体，观察到遗传变异。一些罕见和独特的 ITS 序列变体可有助于识别来自不同地理区域的特定种群。
