Photosynthetic Apparatus and Regulation of Photosynthesisgene Expression in Purple Bacteria

Abstract:

Purple bacteria are extensively used in bacterial photosynthesis research. This review describes the structure of light-harvesting I, light-harvesting II and reaction center of photosynthetic apparatus of purple bacteria and discusses the regulation mechanisms?of photosynthesis (PS) gene transcription, with an emphasis laid on the transcriptional regulation of PS gene by PpsR/AppA system.
