摘要

物种鉴定在生物学、生物地理学、生态学和保护学等领域具有重要意义。Alcea属(malvacae)包括大约70种，主要分布在伊朗-图兰地区，由于其形态特征的均匀性和明显的可塑性，被认为是中东地区最具挑战性的属之一。尽管在伊拉克生长的许多藻属物种分布广泛，但没有关于其遗传多样性、分化模式和扩散模式的任何现有报告。为此，我们对在伊拉克不同生境采集的10种褐藻80份材料进行了分子(SRAP标记)和形态学研究。本研究的目的是:1)SRAP标记是否能够识别伊拉克的Alcea种;2)这些分类群的遗传结构是什么;3)研究物种间的相互关系。本研究表明，结合形态学和SRAP数据可以识别物种。

Delimiting species using DNA and morphological variation in some Alcea (Malvaceae) species based on SRAP markers

Species identification is fundamentally important within the fields of biology, biogeography, ecology and conservation. The genus Alcea (Malvaceae) includes approximately 70 species of mainly Irano-Turanian distribution and is considered one of the most challenging genera of the Middle East, due to its uniformity and pronounced plasticity in morphological traits. In spite vast distribution of many Alcea species that grow in Iraq, there are not any available report on their genetic diversity, mode of divergence and patterns of dispersal. Therefore, we performed molecular (SRAP marker) and morphological studies of 80 accessions from 10 species of Alcea that were collected from different habitats in Iraq. The aims of present study are: 1) can SRAP markers identify Alcea species, 2) what is the genetic structure of these taxa in Iraq, and 3) to investigate the species inter-relationship? The present study revealed that combination of morphological and SRAP data can identify the species.

期刊介绍： Caryologia is devoted to the publication of original papers, and occasionally of reviews, about plant, animal and human karyological, cytological, cytogenetic, embryological and ultrastructural studies. Articles about the structure, the organization and the biological events relating to DNA and chromatin organization in eukaryotic cells are considered. Caryologia has a strong tradition in plant and animal cytosystematics and in cytotoxicology. Bioinformatics articles may be considered, but only if they have an emphasis on the relationship between the nucleus and cytoplasm and/or the structural organization of the eukaryotic cell.
