Abstract

The present study reveals the genetic diversity of Iranian Paracaryum based on morphological and molecular characters of 12 species from 11 provinces of Iran. A total of 118 reproducible bands were generated by 10 of 30 random amplified polymorphic DNA (RAPD) primers, with an average of 11.8 bands per primer and 49% polymorphism. The largest number of effective alleles (Ne), Shannon Index (I) and genetic diversity (H) higher level of Shannon Index (I) and genetic diversity (H) were shown by Paracaryum persicum. Our data depicted the highest similarity between Paracaryum cyclhymenium and P. persicum and the lowest between P. sintenisii and P. bungei. P. bungei showed a relatively low level of genetic variation. Finally, the Neighbor Joining (NJ) trees based on RAPD markers data divided the populations into two different clusters, indicating their genetic difference, which is discussed in detail.

用Rapd标记评价紫草科Paracarum属植物的遗传变异

本文通过对伊朗11个省的12个种的形态和分子特征的分析，揭示了伊朗副伞属植物的遗传多样性。30条随机扩增多态性DNA (RAPD)引物中，10条引物共扩增出118条可重复条带，平均每个引物扩增出11.8条，多态性为49%。有效等位基因数(Ne)、香农指数(I)和遗传多样性(H)最多，香农指数(I)和遗传多样性(H)较高。我们的数据显示，环膜副孢虫与桃孢虫的相似性最高，而与黄盖孢虫的相似性最低。白杨的遗传变异水平相对较低。最后，基于RAPD标记数据的邻域连接树(Neighbor Joining, NJ)将群体划分为两个不同的聚类，并对其遗传差异进行了详细讨论。植物分类单元。29(1):31-41,2022 (6)

期刊介绍： Bangladesh is a humid, subtropical country favouring luxuriant growth of microorganisms, fungi and plants from algae to angiosperms with rich diversity. She has the largest mangrove forest of the world in addition to diverse hilly and wetland habitats. More than a century back, foreign explorers endeavoured several floral expeditions, but little was done for non-vasculars and pteridophytes. In recent times, Bangladesh National Herbarium has been carrying out taxonomic research in Bangladesh along with few other national institutes (e.g. Department of Botany of public universities and Bangladesh Forest Research Institute).
