Abstract

It is possible that the #epsilon# subunit changed the dynamic structure of thylakoid membrane near PSII at low temperature. To test this possibility, the effects of #epsilon# subunit on the fast phase of millisecond delayed fluorescence at different temperatures were compared. At 1 degree C, the increment of the fast phase of ms-DLE was apparent, while at 25 degree C, the increase of the fast phase of ms-DLE cause by the #epsilon# subunit is hard to be measured.
