Abstract [en]

Photosynthesis is one of the most important biological processes on earth, producing carbohydrates and oxygen. The light is captured with the aid of light harvesting proteins. Light harvesting complex proteins in PSII are important both in light absorption and dynamic regulation. This study aims to confirm the individual role of Lhcb1 and Lhcb2 in the regulation of photosynthesis based on the KO lines: koLhcb3, koLhcb5 and koLhcb3koLhcb5. By the tool of western blot, phosphorylation analysis, state transition and non-photochemical quenching, the results indicated that the knock-out of Lhcb3, Lhcb5 or both of them did not cause additional effect on amiLhcb1 and amiLhcb2 single mutants, and then the role of Lhcb1and Lhcb2 has been complement and confirmed.
