This research focuses on the development of grass flowers that produce seed. Grass seeds or grains are major sources of food worldwide. Therefore, understanding the evolutionary processes that gave raise to grass flowers is very important. Knowledge of these processes could lead to development of new food crops to feed our growing population. This study will integrate evolutionary history, gene expression, and plant structure to understand the evolution of grass flowers. The research will focus on the role of two genes that may play an especially important role in the evolution of the grass inflorescence. This project will document floral development in various kinds of grasses and explore the evolutionary history, selection, and the expression of genes controlling floral evolution.Undergraduate and master's students at CSULB, a comprehensive Hispanic-serving institution, will contribute to this research. Data generated will be posted online and new understandings on plant evolutionary development will be incorporated into investigative cases in collaboration with the Botanical Society of America and BioQUEST. The study will provide insights into the mechanisms affecting floral and inflorescence diversification, including crop yield features, among an economically important plant group.

这项研究的重点是草花的发展，产生种子。草籽或谷物是全世界的主要食物来源。因此，了解进化过程，使提高到草花是非常重要的。对这些过程的了解可以导致开发新的粮食作物来养活我们不断增长的人口。这项研究将整合进化历史，基因表达和植物结构，以了解草花的进化。该研究将重点关注两个基因的作用，这两个基因可能在草花序的进化中发挥特别重要的作用。本项目将记录各种草的花发育，并探索控制花发育的进化历史、选择和基因表达。CSULB是一所综合性的西班牙裔服务机构，本科生和硕士生将为这项研究做出贡献。所产生的数据将在网上公布，对植物进化发展的新认识将与美国植物学会和BioQUEST合作纳入调查案例。这项研究将提供深入了解影响花和花序多样化的机制，包括作物产量特征，在一个经济上重要的植物群。
