WebThus, the SS phytoplankton is capable of fast photoadaptation. In earlier studies, it was shown that in the Arctic Ocean, the assimilation number (P b) linearly and positively depended on PAR [47,53,91,92]. The absence of a “plateau” on the curves of the relationships between P b and PAR implies that arctic phytoplankton is light-limited. WebMay 15, 2015 · The photoadaptation defect is independent of light intensity and photoreversion and is not a result of aberrant sub-cellular localization To further characterize the phenotype we examined photoadaptation under a very low light intensity (~1.5 μM m -2 s -1 ) of blue light as well as monitored the cellular localization of the VVD … the wee shop https://uniqueautokraft.com
