Phylogeny and development in Iris subgenus Iris and related species

鸢尾花起源于北方半球，由大约260种具有多彩多维花朵的植物组成。这项提案的重点是了解鸢尾属植物中一个大群体的进化，这一群体在形态上具有多样性，植物从高大到矮小的物种。 将通过对重点群体内的形态和地理多样性进行取样来研究这一群体的演变。此外，还将利用遗传数据评估鸢尾属物种之间的关系。重要的营养和花性状的进化将被检查，作为澄清鸢尾属物种之间的进化关系的结果。此外，这项研究计划亦会进行发展研究，以了解这些精致立体的花卉的形成模式。这类植物具有重要的经济价值，通常在公共和私人花园中使用。在世界上许多地区，鸢尾属植物在自然界中是罕见的，导致一些国家保护所有物种。该项目将培训研究生和本科生;此外，一名国际学生将接受分子遗传技术培训。将为公众和园艺团体举办关于这项研究的研讨会。

Irises originated in the Northern Hemisphere and consist of about 260 species that have colorful multidimensional flowers. This proposal focuses on understanding the evolution of a large group within Irises, a group that is morphologically diverse with plants ranging from tall to dwarf species. The evolution of this group will be studied by sampling the morphological and biogeographical diversity within the focal group. In addition, relationships among Iris species will be assessed using genetic data. The evolution of important vegetative and floral characters will be examined as a result of clarifying the evolutionary relationships among Iris species. In addition, this project will conduct developmental studies to decipher the pattern of formation of the elaborate, tri-dimensional, flowers.This group of plants are of economic importance and are commonly used in public and private gardens. In many regions of the world Iris species are rare in nature leading several nations to protect all species. This project will train graduate and undergraduate students; in addition an international student will be trained in molecular genetic techniques. Seminars on this research will be given to the general public and horticultural groups.
