Abstract

ABSTRACT Phlomis olivieri (Lamiaceae) is a medicinal plant that exhibits diverse variations across a multitude of geographical ranges. Here, we studied the genetic diversity of this species according to start codon targeted (SCoT) markers and morphological variability based on 15 morphological traits. Specifically, the genetic diversity was studied among 100 individuals of 10 geographical populations in Iran. The populations were highly variable in almost all morphological traits (P < .01) and the dendrogram showed four main clusters for morphological traits. Out of the 10 primers, five SCoTs produced 93 reproducible bands, of which 92 were polymorphic. Significant values were observed in the average polymorphic information content (0.35), average band informativeness (18.4), resolving power (6.24) and average polymorphism (98.66%). SCoT markers ultimately grouped P. olivieri populations into six main clusters based on the principal component analysis. Using SCoT alleles, the individuals were grouped into eight distinct genetic clusters. The analysis of molecular variance showed a high degree of genetic variation among the populations (71%) and within the populations (29%). The Mantel test revealed a positive correlation between genetic distance and geographical distance. Thus, morphological features and SCoT markers were informative and reliable in revealing diversity among P. olivieri populations.

伊朗紫叶蕨(Lamiaceae)居群分子形态多样性评价

榄香(Lamiaceae)是一种药用植物，在许多地理范围内表现出不同的变异。本研究利用起始密码子靶向(SCoT)标记和基于15个形态性状的形态变异研究了该物种的遗传多样性。具体而言，对伊朗10个地理种群的100个个体进行了遗传多样性研究。居群在几乎所有形态性状上都存在高度变异(P < 0.01)，在树图上表现出4个主要的形态性状聚类。在10条引物中，5条snp产生93条可重复条带，其中92条为多态条带。平均多态性信息含量(0.35)、平均波段信息量(18.4)、分辨率(6.24)和平均多态性(98.66%)均达到显著水平。基于主成分分析，SCoT标记最终将橄榄木种群划分为6个主要聚类。利用SCoT等位基因，将个体分为8个不同的遗传群。分子变异分析表明，群体间(71%)和群体内(29%)存在高度遗传变异。Mantel检验显示遗传距离与地理距离呈正相关。因此，形态特征和SCoT标记是揭示橄榄树居群多样性的可靠信息。

期刊介绍： The aim of Biodiversity is to raise an appreciation and deeper understanding of species, ecosystems and the interconnectedness of the living world and thereby avoid the mismanagement, misuse and destruction of biodiversity. The Journal publishes original research papers, review articles, news items, opinion pieces, experiences from the field and book reviews, as well as running regular feature sections. Articles are written for a broad readership including scientists, educators, policy makers, conservationists, science writers, naturalists and students. Biodiversity aims to provide an international forum on all matters concerning the integrity and wellness of ecosystems, including articles on the impact of climate change, conservation management, agriculture and other human influence on biodiversity.
