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.

9509189奥尔一组植物激素，细胞分裂素，影响植物生长的许多基本方面，包括芽、根和叶的发育。 植物体内活性细胞分裂素受复杂的酶代谢途径的精细调控，酶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，但尚未报道高等植物中的细胞分裂素代谢突变体。 在本项目中，拟南芥细胞分裂素代谢突变体将使用生化和视觉筛选程序相结合的选择。 细胞分裂素代谢突变体将在植物生理生化、植物发育和遗传实验中得到应用。 在未来，这项研究将允许植物内细胞分裂素的遗传控制和农作物植物的改造，以提高可持续的生产力。
