0000428AmbroseThe International Research Fellow Awards Program enables U.S. scientists and engineers to conduct three to twenty-four months of research abroad. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad.This award will provide Dr. Barbara A. Ambrose with support for twenty-four months work with Dr. Elena Alvarez-Buylla Roces at UNAM's Instituto de Ecologia in Mexico City, Mexico.The objective of this project is to examine the genetic basis of an unusual floral pattern (carpels peripheral, stamens central) in Lacandonia, and compare it with DNA-based phylogeny. The origin of flowers is an important puzzle in the evolution of plants. The project concerns a fundamental aspect of plant development using a model system that is only available in Mexico. This project will make an important contribution to our understanding of flowering plant evolution.Dr. Alvarez-Buylla's lab is fully equipped to develop all state-of-the-art techniques in molecular biology and biochemistry of plants. The host has extensive experience in phylogenetic analyses which will complement the PI's experience in molecular biology techniques. ***

0000428 Ambrose国际研究员奖励计划使美国科学家和工程师能够在国外进行三到二十四个月的研究。 该计划的奖项提供了联合研究的机会，以及使用独特或互补的设施，专业知识和国外的实验条件。Ambrose与墨西哥墨西哥城墨西哥国立自治大学生态研究所的Elena Alvarez-Buylla Roces博士合作了24个月。该项目的目标是研究拉康多尼亚一种不寻常的花型（心皮外围，雄蕊中央）的遗传基础，并将其与基于DNA的植物发生学进行比较。 花的起源是植物进化中的一个重要谜团。 该项目涉及使用仅在墨西哥可用的模型系统进行植物开发的基本方面。 该项目将对我们了解开花植物的进化做出重要贡献。Alvarez-Buylla博士的实验室设备齐全，可以开发植物分子生物学和生物化学方面的所有最先进技术。 宿主在系统发育分析方面具有丰富的经验，这将补充PI在分子生物学技术方面的经验。 ***
