Abstract
This study was aimed at understanding the role of sulfolipids in salt tolerance mechanisms of the halophytes Aster tripolium L., Compositae, and Sesuvium portulacastrum L., Aizoaceae, and of the glycophyte Arabidopsis thaliana (L.) Heynh., Brassicaceae. In Aster and Sesuvium the sulfolipid contents increased significantly under salt stress conditions (517 mM or 864 mM). In Arabidopsis, changes in sulfolipid contents were not observed (NaCl up to 100 mM). The fatty acid profile of sulfoquinovosyldiacylglycerol (SQDG) in Aster was modified with increasing NaCl concentrations. LC-MS analyses of sulfolipids from Aster and Sesuvium revealed the presence of 18:3/18:3 and 16:0/18:3 molecules. Obviously, the function of sulfolipids during salt stress differs between halophytic species and between halophytes and glycophytes where sulfolipid accumulation was not observed.

N1 - Funding information: We are grateful to Dr. G. Dräger, Institute for Organic Chemistry, University of Hannover, for performing the MS verification of SQDG. We would like to thank Prof. Dr. H. Lieth for providing Aster tripolium seeds, Dr. S. Daoud, Morocco, for sending Sesuvium portulacastrum seeds, and Prof. Dr. C. Benning for providing the seeds of the Arabidopsis thaliana of the ecotype Wassilewska. We are grateful for an excellent technical assistance by Julia Volker and Imke Pillukat. We appreciate the valuable work of our gardeners in the greenhouse. The project was supported by a grant from the Land Niedersachsen and by the Graduiertenförderpro-gramm from the University of Hannover.
