Abstract Details

2018, PHD, Kent State University, College of Arts and Sciences / Department of Biological Sciences.
Plants are versatile and diverse photosynthetic eukaryotes. They adapt and flourish in every corner of the earth. Plants have been a vital part of human existence due to their autotrophic ability and therefore abundance. Farming and agricultural advancements have enabled us to use plants as a reliable source of food to meet the continuously increasing food demand. However, crop yield has been affected by the overexploitation of irrigation, misuse of fertilizers and drastic environmental changes. Drought and salinity are among the major causes for loss in crop yield in arid and semiarid parts of the world. In order to meet the demands of a stable food supply we need to find ways to increase crop yield under these severe conditions. Plants overcome environmental stress both biotic and abiotic by modulating their biochemistry. Many of these adaptations are membrane-dependent and mediated via signaling lipids. To understand how plants cope and overcome such stresses we need to take a closer look at its root membrane structure. Biological membranes function as physical barriers that keep the internal and external environment separate and selectively allow transport across this barrier. This makes membranes the first line of defense to all environmental and biological cues. Salinity and draught first affect the plant roots. Membranes i.e. lipid bilayers play a major role in protecting plants by modulating its structure and composition under stress conditions. These stress-signaling events, which help plants to cope with drastic changes, involve the interplay of various proteins and signaling lipids. This dissertation will focus on two such signaling lipids, phosphatidic acid and diacylglycerol pyrophosphate and their interplay with specific target proteins. The work described here brings us closer to understanding the modulations that occur in membrane structure and composition upon stress and how these play a role in salt stress signaling.
