George Akoyunoglou 1927-1986

It is most appropriate to open this conference on "Regulation of Chloroplast Biogenesis" with words of remembrance and honour of our late colleague and my personal friend George Akoyunoglou.

without going into details, a few stepstones of the scientific career of George Akoyunoglou shall be mentioned . He obtained his ph.D. with a study on the carboxydismutase reactions under the guidance of Melvin calvin. He was called back to his home country to become Head of the Photobiology Laboratory and one of the pioneers of the Nuclear Research Center "Demokritos" in Athens. He acted as Head of the Biology Department for many years.

He has spent longer research visits in the laboratories of C. Siron­val in Liege, Bill siegelman in Brookhaven, Itzhak Ohad in Jerusalem and ours in Marburg. George ' s scientific work is marked by the fortunate and successful collaboration with his wife Joan. He represented the unique combination of a Biologist and a Biochemist.

During the 25 years of his scientific work George in collaboration with his wife Joan has set landmarks for the understanding of chloroplast biogenesis. During the transition of etioplasts to chloroplasts they investigated the chlorophyll synthesis, the formation of PS II and PS I and contributed significantly to the understanding of the development of the photosynthetic mechanism. They introduced the intermittent illumina­tion of developing plants for suppressing the formation of the light­harvesting chI alb complex, a technique used worldwide to study the relation between LHC and RC. They elaborated the technique of gel elec­trophoreses of pigment protein complexes and disclosed the sequential binding of chlorophylls to the various integral polypeptides of the thylakoid membrane. Always taking into consideration the biology of the plants they studied, George and Joan Akoyunoglou's work emphasizes the close correlation between the developmental stage of the plant from which the chloroplasts derived and the post-translational regulation of the chloroplast biogenesis.

But even to those who had no intimate knowledge of his scientific work, George Akoyunoglou is known as the outstanding organizer of several most memorable meetings. I mention the "International symposium on

VII

Chloroplast Development" at spetsai (1978), the "5th International Photosynthesis congress" at Halkidike (1980), the "symposium on the Autonomy and Biogenesis of Mitochondria and chloroplasts" at Delphi (1982) and the "International Meeting on the Regulation of chloroplast Differentiation" at Rhodos (1985). Those of us having had the privilege to participate in these meetings experienced George as the perfect organizer. He was everywhere where help was needed, but he never placed himself into the foreground. Perfect organization, the warm and friendly atmosphere and the combination of a program of highest scientific stan­dards with relaxing social events and inspiring cultural excursions became a trade mark of those meetings. During all these meetings George could count on the help of his family and we appreciated their cheerful help during the meetings. George, his family and his coworker Mr. Pastel­lacos appeared as an admirable entity during the past meetings.

As products of the meetings George has edited with various coeditors a number of valuable books. Among them the volumes of the proceedings of the 5th International Photosynthesis Congress still the most comprehen­sive work in photosynthesis literature.

George Akoyunoglou has served in many national and international committees. He took considerable part in the promotion of biology and biochemistry of his own country. He was a founding member of the Hellenic Biochemical and Biophysical society. Last but not least he inspired the foundation of the "International society of Chloroplast Development" for which he was elected as first chairman.

My first personal encounter with George Akoyunoglou was, when he was my chairman at the 3rd International Photosynthese congress in Rehovot (1974). Thereafter we met at various meetings and discussed our mutual research interest. Impressed by his scientific accomplishments and by his personality, I could persuade him to accept a one year guest professor­ship at our university. During this time we became friends. My co-workers and students could not only experience him as an inspiring, stimulating scientist and skillful experimentor but also as a cheerful and charming person who loved to exchange and laugh with them. But he could also be a serious and witty counterpart in long discussions about science, philos­ophy and Greek mythology.

I had the privilege to help George in organizing the last meeting in Rhodes. When most participants were gone, we sat in the lobby of the capsis Hotel and did the last accounting. After we finished, George said to me: Horst, that meeting was fun, let's do it again, and he already planned ahead for this meeting.

We have to be most thankful to George's wife Joan that she fulfilled the plan of George and took all the trouble of organizing this Interna­tional Meeting on the "Regulation of chloroplast Biogenesis".

We dedicate this meeting to the memory of George Akoyunoglou and I am sure it will be held in his sense to serve the scientific progress and friendship in good spirits.

PREFACE

From July 28 to August 3, 1991, an International Meeting on the REGULATION OF CHLOROPLAST BIOGENESIS was held at the capsis Beach Hotel in Aghia Pelaghia, on the island of crete, Greece. The Meeting (Advanced Research Workshop-Lecture Course) was co-sponsored by NATO, FEBS and IUB, and was held under the auspices of the International society for Chloro­plast Development, the Greek Ministry of Industry, Research and Technol­ogy, and the National Center for Scientific Research "Demokritos".

The Meeting focused on recent advances in the field of chloroplast biogenesis and the regulatory mechanisms underlined, and brought together over 120 experts and students of the field from 22 countries. The subject of chloroplast biogenesis has experienced great progress in recent years mainly thanks to the application of Molecular Biology techniques and methodology. New findings that emerge gradually unravel the regulatory mechanisms involved in the assembly, stabilization and growth of the photosynthetic units in thylakoids, the signal transduction chain leading from photoreception to gene expression, the transport of nuclear-coded proteins into stroma-soluble supramolecular enzyme complexes as well as thylakoid-bound supramolecular complexes, involved in light-energy transduction.

It was the aim of this meeting to bring together experts and students coming from diverse disciplines (ranging from Botany and plant physiology to Molecular Biology, Biophysics and Biotechnology), to discuss the recent advances in the field so that thorough exchange of ideas and working hypotheses would be achieved.

The current volume contains near to 90 papers given as lectures or poster presentations in the areas of:

I. Regulation of gene expression

II. Import of nuclear-coded proteins into chloroplasts and mecha­nisms of chloroplast protein translocation

III. Biosynthesis and origin of chloroplast pigments

IV. Regulation of pigment-protein complex formation and assembly into photosynthetic units

V. organization and interactions of photosynthetic units

VI. Adaptation mechanisms in plants and algae-shade adaptation-state transition

VII. Genetic manipulation as a means to monitor assembly and function

I want to express my thanks to all who contributed to the Meeting and to this volume. My sincere thanks are also due to members of the Interna­tional Organizing committee, and especially to Prof. Dr. Horst senger, for their help, to my collaborators in "Demokritos", and especially to Mr. Leonidas Pastelakos and Ms Mitsy Akoyunoglou for their efficient and never expiring assistance.

August 1991 Athens, Greece
