Re-modeling of foliar membrane lipids in a seagrass allows for growth in phosphorus-deplete conditions.

In this study, we used liquid chromatography high-resolution tandem mass spectrometry to analyze Shirt the lipidome of turtlegrass (Thalassia testudinum) leaves with either extremely high phosphorus content or extremely low phosphorus content.Most species of phospholipids were significantly down-regulated in phosphorus-deplete leaves, whereas diacylglyceryltrimethylhomoserine (DGTS), triglycerides (TG), galactolipid digalactosyldiacylglycerol (DGDG), certain species of glucuronosyldiacylglycerols (GlcADG), and certain species of sulfoquinovosyl diacylglycerol (SQDG) were significantly upregulated, accounting for the change in phosphorus content, as well as structural differences in the leaves of plants growing click here across regions of varying elemental availability.These data suggest that seagrasses are able to modify the phosphorus content in leaf membranes dependent upon environmental availability.
