This project's aims are to focus on the novel cyclic glucans produced by Bradyrhizobium, a group of legume-nodulating bacteria involved in symbiotic dinitrogen fixation. Detailed structural characterization of the glucans, elucidation of the mechanisms of biosynthesis, assessment of their potentials in regulating osmotic adaptation, and as inducers of phenylpropanoid metabolism will be undertaken. These studies should enlarge our understanding of the roles played by these molecules in the free-living bacteria and during the process of leguminous plant nodulation. //

该项目的目标是重点研究慢生根瘤菌（Bradyrhizobium）产生的新型环葡聚糖，慢生根瘤菌是一组参与共生二氮固定的豆科植物结瘤细菌。 将进行葡聚糖的详细结构表征，阐明生物合成机制，评估其调节渗透压适应的潜力以及作为苯丙素代谢诱导剂。 这些研究应该扩大我们对这些分子在自由生活的细菌中以及豆科植物结瘤过程中所发挥的作用的理解。 //
