This award will support collaborative research between Professor Elizabeth D. Earle, Cornell University, and Professor C.J. Leaver, University of Edinburgh, Scotland, in the field of plant molecular biology. The genomes--arrangement of genes--in cereal mitochondria, such as maize, will be studied by means of tissue culture and the propagation of the observable characteristic of male sterility in these plants. Professor Earle's earlier work has led to the development of culture methods for "tailored" genomes in various vegetables. By means of tissue culturing, fusions of genes into new genomes, which may be less or more resistant to certain diseases or environmental threats, is possible. The intent of the work here is to extend these techniques to study agriculturally important problems in other crops. New materials for this study will be cultured in Professor Earle's laboratory, providing a rich source of mitochondrial diversity for subsequent analysis, to be performed in the laboratory of her U.K. collaborator. The results of this complementary research may lead to the development of new and useful variants of important crops.

该奖项将支持伊丽莎白D教授之间的合作研究。Earle，Cornell University和C. J. Leaver教授，爱丁堡大学，苏格兰，在植物分子生物学领域。将通过组织培养和繁殖这些植物中可观察到的雄性不育特征来研究谷物线粒体（如玉米）中的基因组-基因排列。厄尔教授早期的工作已经导致了各种蔬菜中“定制”基因组的培养方法的发展。通过组织培养，将基因融合成新的基因组是可能的，新的基因组对某些疾病或环境威胁的抵抗力可能更低或更高。这项工作的目的是将这些技术扩展到研究其他作物的农业重要问题。这项研究的新材料将在Earle教授的实验室中培养，为随后的分析提供丰富的线粒体多样性来源，这些分析将在她的英国实验室进行。合作者这项补充研究的结果可能会导致重要作物的新的和有用的变种的开发。
