Highlights
- •
- We examined the membrane-forming lipids for 10 wild halophytes.
- •
- The plants are classified: (1) euhalophytes, crynohalophytes, glycohalophytes; (2) mesoxerophytes and xeromesophytes.
- •
- The similarity in glycolipids relates to the water factor whereas phospholipids relates to the type of salt accumulation.
- •
- The fatty acid composition of the plants is determined at the species level.
Abstract
The
composition of membrane-forming lipids has been examined for 10 wild
halophyte species growing in southern Russian on alkaline soil. The
plants belong to seven taxa of family rank: by their life form, which
are semi-shrubs, herbaceous annuals, and perennial plants; their salt
tolerance, which are classified as the euhalophytes, crynohalophytes,
and glycohalophytes; and by their sensitivity to water, classifications
of mesoxerophytes and xeromesophytes. Parallels have been found between
the lipid composition and the ecological status of the plants. It has
also been revealed that the similarity in the glyco- and phospholipid
composition of different plant groups relates to the water factor and
the type of salt accumulation, respectively. The fatty acid compositions
of the examined plants is determined at the species level.
