LITERATURE
activity decreased upon S deficiency
-
activity increases upon the increase of salinity
-
DSYB transcription levels increases with dimethylsulfoniopropionate concentrations
high salinity and nitrogen limitation stresses cause the increase of dimethylsulfoniopropionate content and TpMMT protein in Thalassiosira
increased dimethylsulfoniopropionate production and DsyB transcription levels are observed, to varying degrees, in response to increased salinity, decreased nitrogen, decreased temperature and in stationary phase compared to the exponential growth phase
