Lipidome of the Brown Macroalga <i>Undaria pinnatifida</i>: Influence of Season and Endophytic Infection
An analysis of the lipidome of the brown alga <i>Undaria pinnatifida</i> (Laminariales) was performed’ more than 900 molecular species were identified in 12 polar lipids and 1 neutral lipid using HPLC/MS-MS. The seasonal changes of <i>U. pinnatifida</i> lipidome were determin...

| description | An analysis of the lipidome of the brown alga <i>Undaria pinnatifida</i> (Laminariales) was performed’ more than 900 molecular species were identified in 12 polar lipids and 1 neutral lipid using HPLC/MS-MS. The seasonal changes of <i>U. pinnatifida</i> lipidome were determined. It was shown that acclimatization to winter and spring was accompanied by an increase in the unsaturation of both polar and neutral lipids. In autumn and summer, on the contrary, the contents of more saturated molecular species of all lipid classes increased. Based on the data obtained, a scheme for the polar and neutral lipid synthesis in brown algae was proposed. In addition, the influence of infection with the brown filamentous endophyte <i>Laminariocolax aecidioides</i> (Ectocarpales) on <i>U. pinnatifida</i> lipidome was studied. It was found that infection has the most noticeable effect on the molecular species composition of triacylglycerides, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, and phosphatidylhydroxyethylglycine of the host macrophyte. In infected samples of algae, changes in the composition of triacylglycerides were revealed both in areas with the presence of an endophyte and in adjacent intact tissues, which may indicate the occurrence of a secondary infection. |
