This is a Small Grant for Exploratory Research. Bacterial genes for poly-beta-hydroxybutyrate (PHB) will be transferred from the bacterium Alcaligenes eutrophus into the plant Arabidopsis thaliana. It will then be possible to determine whether or not these genes can be expressed in plants, and whether or not the PHB made is stable. If these preliminary experiments are successful further experiments would be undertaken to maximize the concentration of PHB in the plant tissues. PHB forms a biodegradable plastic and efficient expression in plants could lead to reducing its costs to practical levels. These experiments could also help answer the question of why plants abandoned PHB as a storage compound in favor of starch and oils.

这是探索性研究的一小笔助学金。聚β-羟基丁酸酯(PHB)的细菌基因将从产碱菌转移到植物拟南芥中。然后就可以确定这些基因是否可以在植物中表达，以及所制得的PHB是否稳定。如果这些初步实验成功，将进行进一步的实验，以最大限度地提高植物组织中PHB的浓度。PHB形成了一种可生物降解的塑料，在植物中的高效表达可以将其成本降低到实用水平。这些实验还有助于回答为什么植物放弃PHB作为储存化合物，转而使用淀粉和油。
