RPG: A Genetic Approach to Cytokinin Metabolism and Function in Plant Development

9509189 AUER一组植物激素，即细胞分裂素，影响植物生长的许多基本方面，包括地上部、根和叶的发育。植物中活跃的细胞分裂素受到复杂的酶代谢途径的精细调控，这些代谢途径还控制着细胞分裂素的运输、储存和失活。虽然单基因植物突变体已被用于研究其他植物激素的生物化学，但在高等植物中尚未见细胞分裂素代谢突变体的报道。在这个项目中，拟南芥细胞分裂素代谢突变体将使用生化和目视筛选相结合的程序进行筛选。这些细胞分裂素代谢突变体将用于植物生理、生物化学、植物发育和遗传实验。在未来，这项研究将允许在植物中对细胞分裂素进行遗传控制，并对农业作物进行改造，以提高可持续的生产力。

9509189 Auer One group of plant hormones, the cytokinins, influence many fundamental aspects of plant growth including shoot, root and leaf development. The active cytokinins in the plant are delicately regulated by complex enzymatic metabolism pathways which also control cytokinin transport, storage and inactivation. While single-gene plant mutants have been used to study the biochemistry of other plant hormones, no cytokinin metabolism mutants have been reported in higher plants. In this project, Arabidopsis thaliana cytokinin metabolism mutants will be selected using a combination of biochemical and visual screening procedures. The cytokinin metabolism mutants will be used in plant physiology, biochemistry, plant development and genetic experimelts. In the future, this research will allow the genetic control of cytokinins within plants and the modification of agricultural crop plants to increase sustainable productivity.
