Phylogenetic methods can aid for an understanding of evolutionary relationships. The goal of this research is to advance our understanding of systematic and biology of Asian Iris by creating a phylogenetic framework for taxonomic revision, and testing species divergence and dispersal in Iris. This research will focus on geographic origins and evolutionary relationships of Asian Iris. The purpose this search is to construct a robust phylogenetic analysis of series Chinensis and to resolve the placement of this series within subgenus Liminiris. Using a phylogenetic approach, we will examine geographic origins of series Chinensis, small irises that are distributed in Asia; China, Korea, and Japan. We proposed to investigate which Asian species should be included in series Chinensis; phylogenetic relationships among series Chinensis species; and the origin, dispersal, and diversification of the series in Asia. We will apply molecular marker to phylogenetic relationships and use these results to test hypotheses about geographic distribution. The work will be carried out under the supervision of Dr. Seung-Chul Kim, Professor and Curator, Department of Biological Sciences at the Sungkyunkwan University in South Korea.This research will focus on geographic origins and evolutionary relationships of Asian Iris. We propose to investigate which Asian species should be included in series Chinensis; phylogenetic relationships among series Chinensis species; and the origin, dispersal, and diversification of the series in South Korea. Nuclear and chloroplast DNA makers will be sequenced for phylogeny reconstruction using Maximum Likelihood and Bayesian Statistical methods. The resulting phylogeny will be used as a framework for testing hypothesis on patterns of geographic diversification.This award, under the East Asia and Pacific Summer Institutes program, supports summer research by a U.S. graduate student and is jointly funded by NSF and the National Research Foundation of Korea.

系统发育方法可以帮助理解进化关系。这项研究的目的是通过为分类法修订创建系统发育框架，测试虹膜的差异和散布来提高我们对亚洲虹膜系统和生物学的理解。这项研究将侧重于亚洲虹膜的地理起源和进化关系。该搜索的目的是构建串联丛生的鲁棒系统发育分析，并解决该系列在liminiris子中的位置。使用系统发育方法，我们将检查串联的Chinensis的地理起源，这些小虹膜分布在亚洲。中国，韩国和日本。我们提出要调查中性串联应包括哪些亚洲物种。串联的中质物种之间的系统发育关系；以及亚洲系列的起源，分散和多样化。我们将将分子标记物应用于系统发育关系，并使用这些结果来测试有关地理分布的假设。这项工作将在韩国Sungkyunkwan大学生物科学系Seung-Chul Kim博士的监督下进行。这项研究将重点关注亚洲Iris的地理起源和进化关系。我们建议调查中性串联应包括哪些亚洲物种；串联的中质物种之间的系统发育关系；以及该系列在韩国的起源，分散和多样化。使用最大似然和贝叶斯统计方法，将对核成形器DNA制造商进行系统发育重建。由此产生的系统发育将用作测试地理多样化模式的假设的框架。根据东亚和太平洋夏季研究所计划，该奖项支持美国研究生的夏季研究，并由NSF和国家研究基金会共同资助。
