项目摘要

Humans have used Brassicas for thousands of years as a source of food, energy and medical cures. Plant architecture, leaf form, and flower and fruit structure have evolved independently and multiple times in wild and domesticated Brassicas. Little is known about how these important and diverse groups of plants are related to each other. Integrating the knowledge about genetic relationships with morphological data will help to decipher the dynamics of evolution and plant domestication. The research goals for this study are to: (1) Understand the evolutionary relationships among Brassica crops and wild relatives(2) Examine the evolution of morphology(3) Relate morphological evolution with gene molecular variationThe proposed methods offer new and inexpensive ways to sequence multiple genes at once while simultaneously providing an innovative way to understand plant development. Graduate and undergraduates students will be trained on the methods developed here, including an online resource for the scientific community. An ?evo-devo? lab that takes advantage of college freshman?s familiarity with the grocery store Brassica oleracea (cabbage, broccoli, cauliflower, kale, etc.) will be implemented. Outreach to the public through the Columbia Center of Urban Agriculture (CCAU) is planned.

数千年来，人类一直使用大麻作为食物、能量和医疗的来源。植物结构，叶的形式，花和果实的结构已经独立和多次在野生和驯化的拟南芥。人们对这些重要而多样的植物群是如何相互联系的知之甚少。将有关遗传关系的知识与形态学数据相结合将有助于解释进化和植物驯化的动力学。本研究的目的是：（1）了解芸苔属作物和野生近缘种之间的进化关系（2）研究形态的进化（3）将形态进化与基因分子变异联系起来。所提出的方法提供了一种新的、廉价的方法来同时测定多个基因的序列，同时为了解植物发育提供了一种创新的方法。研究生和本科生将接受这里开发的方法的培训，包括科学界的在线资源。安？进化进化利用大学新生的实验室吗他熟悉杂货店的甘蓝（卷心菜、花椰菜、花椰菜、羽衣甘蓝等）。将得到执行。计划通过哥伦比亚城市农业中心（CCAU）向公众推广。
