The PSI-O subunit of plant photosystem I is involved in balancing the excitation pressure between the two photosystems.

The Journal of biological chemistry - 4 Jun 2004

Abstract excerpt

PSI-O is a subunit of photosystem I in eukaryotes. The function of PSI-O was characterized in Arabidopsis plants using RNA interference. Several transformants with the psaO-RNAi construct were generated, and a high proportion of the plants contained only very little or virtually no residual PSI-O. Plants lacking PSI-O have a 50% reduction in state transitions indicating a role for PSI-O in the balancing of...
