    ESI-MS/MS Characterization of Glycerolipids and Seasonal Alteration in their Composition in Sesuvium Portulacastrum (Linnaeus) -A Salt Marsh Halophyte
    Author(s): Solimabi Wahidullah*, Safia Khan and Prabha Devi

    Plants adapt and survive adverse environmental changes by altering their membrane lipid composition. Sesuvium portulacastrum L., a facultative halophyte has been extensively studied for its adaptability to various abiotic stresses. However, knowledge on the identification of glycerolipids and changes in their profile in coping up with the stressors is limited. In this investigation, electrospray ionization tandem mass spectrometry (ESI?MS/MS) was used for identifying glycerolipid molecular species in the halophyte and to study changes in their profile during pre- and post monsoon seasons. The study showed when environmental conditions changed from post to premonsoon season, the lipidome switched from galactoglycerolipids, such as monogalactosyl diacylglycerol (MGDG, GL1), lyso-digalactosyl diacylglycerol (lyso-DGDG,GL2) and digalactosyl monoacylglycerol phosphatidic acid (DGMAPA, GL3)..
