Science+Business Media (www springer.com) Preface This book titled Lipids in Plant and Algae Development aims at summarizing recent advances in function of lipids in plant and algal development As a primary biomolecule, lipids have structural as well as diverse physiological functions such as essential constituents of biological membranes, sustainable carbon energy storage, and active signal transducer in cellular processes In the past few decades, plant and algal lipids have gone through an established biochemistry, enzymology, and analytical chemistry, which revealed distinct functions of specific lipid classes based on their physical and biochemical properties Upon entry into the postgenomic era, gene knockout studies on the lipid-related genes rapidly uncover functional aspects of lipids Owing to a pile of recent publications that discuss how lipids modulate critical biological processes in plants and algae, a new axis is being developed which classifies global lipidome on a physiological basis Our conceptual novelty in this book is to summarize our recent understanding of lipids from the viewpoint of developmental context Furthermore, we put together the discussion of algal and plant lipids so as to contrast the lipid function and underlying evolutionary context in photosynthetic unicellular and multicellular organisms The first chapter gives a general overview on lipids, including their structures, metabolism, and analytical tools The subsequent chapters can be grouped into three major parts: part I, lipids in photosynthesis (Chaps 2, 3, 4, 5, 6, and 7); part II, lipids in development and signaling (Chaps 8, 9, 10, 11, 12, 13, 14, 15, 16, and 17); and part III, lipids in industrial applications (Chaps 18, 19, and 20) The subjects of each chapter cover the fast-moving topics in the field of plant and algal lipids, inviting contribution by the internationally recognized expert groups, so that the book provides refreshing viewpoint in addition to the solid discussion by established authority Given the current fascination of plants and algae in carbon fixation and their potential as an alternative source for production of energies or novel chemical molecules, this book would also encompass what plants or algae can in the field of industrial applications This book would not have been published without valuable contributions by many of our friends and colleagues First of all, we are grateful to the authors of the individual chapters who kindly agreed to devote their time and effort to provide this v vi Preface book with the highest degree of

Lipids are one of the major subcellular components, and play numerous essential functions As well as their physiological roles, oils stored in biomass are useful commodities for a variety of biotechnological applications including food, chemical feedstocks, and fuel Due to their agronomic as well as economic and societal importance, lipids have historically been subjected to intensive studies Major current efforts are to increase the energy density of cell biomass, and/or create designer oils suitable for specific applications This chapter covers some basic aspects of what one needs to know about lipids: definition, structure, function, metabolism and focus is also given on the development of modern lipid analytical tools and major current engineering approaches for biotechnological applications This introductory chapter is intended to serve as a primer for all subsequent chapters in this book outlining current development in specific areas of lipids and their metabolism Keywords Fatty acids • Lipid biotechnology • Lipid metabolism • Lipid analysis • Algae • Plants Y Li-Beisson (*) Institut de Biologie Environnementale et Biotechnologie, UMR 7265 CEA - CNRS

particularly a decrease in sugar phosphates and an increase in several amino acids (Osanai et al 2014c) In Synechococcus, RpaA is a cognate response regulator of SasA (Takai et al 2006) The cognate response regulator of Hik8 in Synechocystis 6803 remains to be determined The Synechocystis 6803 genome contains a gene encoding the histidine kinase Hik31 (sll0790) in the chromosome, and the homolog of Hik31 (slr6041), which is 95.7 % identical to Hik31 (sll0790) at the amino acid level, is encoded by the plasmid in Synechocystis 6803 (Kahlon et al 2006) The hik31 knockout mutant could not grow under mixotrophic conditions (in the presence of mM glucose), and the G6PD activity was increased to more than twice that of the wild-type strain (Kahlon et al 2006) Importantly, the authors claimed the instability of phenotypes of the hik31 mutant (Kahlon et al 2006), a fact consistent with our transcriptome analysis; among all histidine kinases in Synechocystis 6803, only hik31 exhibited a large value of standard deviations (Osanai et al 2006) The deletion mutant of the plasmid operon of the hik31 ortholog (slr6039-slr6041) lost its viability under dark conditions, and the expression levels of glgP and zwf were decreased, the expression of glgC, fbaI, fbaII (encoding fructose-1,6-bisphosphate aldolases), gap2 (encoding glyceraldehyde-3-phosphate dehydrogenase), and pdh (encoding pyruvate dehydrogenase) were increased (Nagarajan et al 2014) Cell division and copper resistance were abolished by the deletion of the hik31 operon (Giner-Lamia et al 2012; Nagarajan et al 2012), suggesting that Hik31 plays multiple roles in primary and secondary metabolism and cell proliferation Hik31 is localized to both the plasma and thylakoid membranes (Giner-Lamia et al 2012) and Rre34/CopR, whose gene is included in the hik31 operon, is a probable cognate response regulator of Hik31 in Synechocystis 6803 Engineering of Sugar Catabolism in Synechocystis 6803 for Bioplastics and Hydrogen Production Metabolic engineering involves the alteration of cellular metabolisms by genetic modification to increase products of interest, and has a long history of studies Overexpressing and/or increasing the activities of metabolic enzymes are straightforward methods of metabolic engineering; however, researchers often encounter only marginal increases in productivity Since multiple genes should be modified simultaneously to alter metabolism and increase the products of interest, Alper and Stephanopoulos (2007) put forward global transcription machinery engineering (gTME), which alters transcription factors and sigma factors rather than metabolic enzymes As mentioned in section “Transcriptional regulators controlling sugar catabolism in Synechocystis 6803”, several transcriptional regulators that control the expression of genes of sugar catabolism have been identified in Synechocystis 6803, and therefore, our group tried to use these factors for metabolic engineering To generate the sigE-overexpressing strain, a sigE open reading frame was fused with 20 Understanding Sugar Catabolism in Unicellular Cyanobacteria Toward… 519 the psbAII promoter and integrated into a neutral site of the Synechocystis 6803 genome The sigE-overexpressing strain exhibited an increased expression of enzymes of glycogen catabolism and the OPP pathway, and decreased glycogen levels under photoautotrophic conditions (Osanai et al 2011) Metabolome analysis revealed that acetyl-CoA, citrate, and isocitrate levels were increased by sigEoverexpression, indicating enhanced sugar catabolism by sigE overexpression (Osanai et al 2011) Synechocystis 6803 accumulates PHB, one of the biodegradable polyesters grouped in polyhydroxyalkanoates (PHAs), during nitrogen starvation (Hein et al 1998) PHB is synthesized from acetyl-CoA by three reactions: acetoacetyl-CoA synthesized from acetyl-CoA by ketothiolase (encoded by phaA), 3-hydroxybutylyl-CoA synthesized from acetoacetyl-CoA by acetoacetyl-CoA reductase (encoded by phaB), and PHB synthesized from 3-hydroxybutylyl-CoA by PHA synthase (encoded by phaC and phaE) (Hein et al 1998) Microarray analysis suggested that the expression of phaC and phaE was up-regulated by sigE overexpression (Osanai et al 2011) The levels of PHB in the sigE-overexpressing strain after nitrogen deprivation were 2.5 times that in the wild-type strain (Osanai et al 2013b) Another microarray analysis indicated that the transcripts of phaA and phaB were increased by rre37 overexpression, and the PHB levels were doubled in the rre37-overexpresing strain compared with the wild-type strain (Osanai et al 2014a) PHB was additively increased by the double overexpression of sigE and rre37, suggesting that SigE and Rre37 activate the PHB biosynthetic pathway in parallel (Osanai et al 2014a) (Fig 20.3) Thus, overexpression of the transcriptional regulators increased the PHB levels in Synechocystis 6803, demonstrating that gTME is also an effective method for metabolic engineering in cyanobacteria Microarray analysis also suggested that the expression of hoxEFUYH was upregulated by sigE overexpression, which was confirmed by quantitative realtime PCR (Osanai et al 2011, 2013a) Hydrogen is accumulated during anaerobic Fig 20.3 Schematic model of activation of sugar catabolism and polyhydroxybutyrate biosynthesis by SigE and Rre37 (red arrows indicate the transcriptional activation by SigE and Rre37) 520 T Osanai et al conditions, and it was found that the levels of accumulated hydrogen were higher in the sigE-overexpressing strain than in the wild-type strain under both light and dark conditions (Osanai et al 2013a) Thus, SigE regulates the genes related to sugar catabolism, PHB biosynthesis, and hydrogen production As mentioned in section “Two transcription factors belonging to the AbrB-family”, AbrB transcription factors regulates the expression of enzymes related to primary metabolism and hydrogen production, suggesting the close relationship among carbon, nitrogen, and hydrogen metabolism in Synechocystis 6803, although its physiological meaning is unclear at present Conclusion In this review, we have summarized the recent progress of studies on the primary metabolism of unicellular cyanobacteria by focusing on Synechocystis 6803 sugar catabolism and transcriptional regulators Several transcriptional regulators of sugar metabolism in Synechocystis 6803 have been identified and molecular mechanisms of the signal transduction of light/dark, day/night, and nutrient status have been elucidated In addition to basic science, there are examples of which mutants of transcriptional regulators of sugar catabolism increased high-value products, opening up the novel strategy of the metabolic engineering of Synechocystis 6803 The advances in the applied sciences of cyanobacteria will contribute to generations of renewable energy and alternative materials, and the basic knowledge about cyanobacterial transcription and metabolism will be indispensable for the sustainable development of human society Acknowledgments This work was supported by the Ministry of Education, Culture,
