9631458 Bowman Cereals, legumes, nuts, and fruits of angiosperms provide a large portion of the food that is consumed by both humans and livestock. Each of these products is ultimately derived from carpels, the female reproductive organs of the flower. Carpels are generated in developing flowers through the action of many genes. The aim of this project is to identify the basic molecular and genetic mechanisms by which the development of carpels is directed. Since all angiosperms are likely to utilize a common set of regulatory genes, by cloning and characterizing the relevant genes in the model species Arabidopsis, Dr. Bowman can apply the knowledge gained to commercially important crop species. Genetically engineered changes in sizes, numbers, structure and rate of maturity of carpels will eventually be possible. Such manipulations in crop species may lead to improvements in the amount and diversity of our food supply.

谷物、豆类、坚果和被子植物的果实提供了人类和牲畜消耗的大部分食物。这些产品中的每一种最终都来自心皮，这是花的雌性生殖器官。心皮是在花发育过程中通过多种基因的作用而产生的。本项目的目的是确定心皮发育的基本分子和遗传机制。由于所有被子植物都可能利用一套共同的调控基因，通过克隆和表征模式物种拟南芥的相关基因，鲍曼博士可以将所获得的知识应用于商业上重要的作物物种。通过基因工程改变心皮的大小、数量、结构和成熟速度最终将成为可能。这种对作物品种的操纵可能会改善我们食物供应的数量和多样性。
