Regulation of thylakoid assembly in response to environment

本工作研究了莱氏绿色衣藻光系统比例的调节。结果表明，绿色藻类，很像蓝藻和高等植物，调整和优化两个光系统的比例，以响应在生长过程中的辐照质量。这种调整是补偿反应，帮助莱茵衣藻保持接近理论最大值的光合作用量子效率。绿色藻类中PSI/PSII比率调节的分子反馈机制的操作的detwection加强了在可能所有的氧进化光合生物中这种机制的高度保守性的概念。本工作从PSI/PSII比值的调节方面阐明了色彩对莱氏锦鸡儿叶绿体叶绿素积累的影响。结果表明，不同的光感受器参与了这两种现象的调节。在这项工作中的发现，预计将作为未来的生化和诱变实验的基础，旨在确定重要的酶的信号转导途径中的步骤，因此，它将有助于阐明的分子机制PSI/PSII的比例调整在有氧光合作用。

The work addresses the adjustment of the photosystem ratio in the green alga Chlamydomonas reinhardtii. It is shown that green algae, much like cyanophytes and higher plants, adjust and optimize the ratio of the two photosystems in response to the quality of irradiancxe during growth. Such adjustments are compensation reactions and help C.reinhardtii to retain a quantum efficiency of photosynthesis near the theoretical maximum. The detwection of the operation of a molecular feedback mechanism for the PSI/PSII ratio adjustment in green algae strengthens the notion of the highly conserved nature of this mechanism among probably all oxygen evolving photosynthetic organisms. The work delineates chromatic effects on chlorophyll accumulation in the chloroplasts of C.reinhardtiifrom those pertaining to the regulation of the PSI/PSII ratio. It is shown that different photoreceptors are involved in the regulation of the two phenomena. Findings in this work are expected to serve as the basis of future biochemical and mutagenesis experiments aimed to identify important enzymatic steps in the signal transduction pathway and, thus, it will contribute to the elucidation of the molecular mechanism for the PSI/PSII ratio adjustment in oxygenic photosynthesis.
