Phylogeny and development in Iris subgenus Iris and related species

鸢尾花起源于北半球，由大约260个种类组成，它们拥有丰富多彩的多维度花朵。该提案的重点是了解鸢尾植物中一个大群体的进化，这个群体的植物形态多样，从高大到矮小的物种都有。这一群体的演变将通过在焦点群体内取样形态和生物地理多样性来研究。此外，还将利用遗传数据评估鸢尾物种之间的关系。为了阐明鸢尾属植物间的进化关系，研究了重要的营养性状和花性状的进化。此外，该项目将进行发育研究，以破译精致的三维花朵的形成模式。这组植物具有重要的经济价值，通常用于公共和私人花园。在世界许多地区，鸢尾花在自然界中是罕见的，导致一些国家保护所有物种。本项目将培养研究生和本科生；此外，一名国际学生将接受分子遗传技术方面的培训。将为公众和园艺团体举办有关这项研究的研讨会。

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.
