Light Energy Transfer Between Phycobiliproteins and Thylakoids of Higher Plants

Wu Xiao-nan,Zhou Bai-cheng and Zeng Cheng-kui(C. K. Tseng)   

Abstract: The excited energy transfer from phycobiliproteins to thylakoids of higher plants was investigated. When incubated with spinach thylakoids, phycobiliproteins isolated from red and blue-green algae have transferred the light energy which they absorbed to spinach PS Ⅱ. The efficiency of energy transfer dependent upon the kind of phycobiliproteins used. If spinach thylakoids were replaced by thylakoids of Brassica chinensis; R-phycoerythrin or C-phycocyanin could transfer the excited energy to PS Ⅱ of B. chinensis only in the presence of allophycocyanin.

Key words: Phycobiliproteins, Spinacia oleracea, Brassica chinesis Thylakcids, PS Ⅱ
