Phylogeny and Development of the Panicoid Grasses

9815392凯洛格世界粮食供应主要依赖于三种作物：水稻、玉米和小麦。 这些都被归类为草家族的成员，有许多遗传和发育相似之处。 因为它们是如此密切相关，这意味着研究其中任何一个有助于了解所有其他人。 这也意味着对任何其他非作物草的研究都可以提供最终用于作物研究的基本数据。 该项目研究与玉米关系最密切的禾本科植物，包括甘蔗、高粱、谷子、珍珠粟和普通粟，以及大约2000种其他物种。 我们将通过比较它们的DNA序列来确定哪些植物与作物最接近。 我们还将研究植物如何发育，以确定它们的花和种子是如何形成的。 2000种圆锥花序草无疑含有可用于作物改良的基因。 该项目将产生“路线图”，一个关系图和发育变化的描述，将指导这些基因的搜索和理解。

9815392 Kellogg The world's food supply depends primarily on three crops: rice, corn (maize), and wheat. These are all classified as members of the grass family and have many genetic and developmental similarities. Because they are so closely related, it means that studying any one of them helps understand all the others. It also means that study of any other non-crop grasses can provide basic data that will ultimately be used for crop research. This project studies the grasses most closely related to maize, a group that includes sugar cane, sorghum, foxtail millet, pearl millet, and common millet, and approximately 2000 other species. We will determine which plants are most closely related to the crops by comparing their DNA sequences. We will also study how the plants develop to determine how their flowers and seeds form. The 2000 species of panicoid grasses undoubtedly contain genes that will be of use for crop improvement. This project will produce the "road map", a diagram of relationships and description of developmental change, that will guide the search for and understanding of those genes.
