Characterization of C3 Phosphoenolpyruvate Carboxylase Isoforms that Operate in an Inducible C4-Type PhotosyntheticSystem

9604518 Bowes Bowes博士多年来一直致力于光合作用中碳固定的机制。 他的工作最近进入了一个新的领域，除了生化分析外，实验室现在还使用基因表达的分子分析。 除了三种基本类型的碳固定机制，Bowes博士现在又增加了一种。 他的研究小组检测到的植物，显示诱导方面的C4代谢，而不表达形态/解剖学特征的这一途径。 提出的工作有望提供新途径的分子，进化和生理方面的整合。 该小组将分离该途径关键酶的转录本，将其置于进化背景中，并研究这些酶的生化特征。 重点是活性调节的差异，可以预期区分的酶时，植物在不同的固定模式。

9604518 Bowes Dr. Bowes has worked on the mechanisms of carbon fixation during photosynthesis for many years. His work has recently moved into a new area, and the laboratory is now using molecular analysis of gene expression in addition to biochemical analyses. Adding to the three basic types of carbon fixation mechanisms, Dr. Bowes now adds another one. His group detected plants which show inducible aspects of C4 metabolism without expressing the morphological/anatomical characteristics of this pathway. The work proposed promises to provide an integration of molecular, evolutionary and physiological aspects of the new pathway. The group will isolate the transcripts for key enzymes of the pathway, place them into an evolutionary context and study the biochemical characteristics of these enzymes. The focus is on the differences in activity regulation that can be expected to distinguish the enzymes that are expressed when the plants are in different fixation modes.
