Genetic and Hormonal Interactions Controlling Shoot Growth

本项目将确定植物生长如何在遗传、生化和生理水平上受到调节，以及植物激素如何在基因型和整体表型（表型）之间提供关键联系。这项工作使用豌豆作为模型，因为有大量可用的突变体，而且该物种适合进行生理和生化研究。我们的研究结果将允许将茎生豌豆植物与其他具有不同生长习惯的模式物种（如拟南芥）进行发育比较。该项目意义重大，因为它将使芽的生长通过基因或化学修饰来满足特定的农艺目标。

This project will determine how plant growth is regulated at the genetic, biochemical, and physiological levels, and how plant hormones provide key links between the genotype and overall phenotype (phenome). The work uses peas as a model because of the wealth of mutants available and the suitability of the species for physiological and biochemical studies. Our results will allow comparison of development in the caulescent pea plant with other model species with different growth habits, such as Arabidopsis. The project is significant because it will enable shoot growth to be modified either genetically or chemically to meet particular agronomic objectives.
