Impact of the salt stress on the photosynthetic carbon flux and 13C-label distribution within floridoside and digeneaside in Solieria chordalis

This work describes a pulse-chase labelling experiment with NMR detection in order to investigate the flux of photosynthetic carbon, the isotopomers composition and 13C-label distribution in the low-molecular weight carbohydrates (floridoside and digeneaside) from the red alga Solieria chordalis, incubated in different salinities media (22, 34 and 50 psu).
