Celebrating 20 years of historical papers in Photosynthesis Research★ (original) (raw)
Related papers
The history of photosynthesis research can be found in original papers and books. However, a special history is available from the prefatory chapters and the personal perspectives of various researchers who published them in several journals over the last 40 years. We have compiled a list of such perspectives published since 1964. Selection is not easy, especially of authors who were not directly engaged in pho-tosynthesis research; some are included for their special insights related to central issues in the study of photosynthesis. Our journal, Photosynthesis Research, contains other valuable historic data in the occasional tributes, obituaries and historical notes, that have been published. Lists of these items are included.
Personal recollections of 40 years in photosynthesis research*
1999
The major theme of my work in photosynthesis has been electron transport in green plant thylakoids. In particular, we investigated the properties and the role of the NADP-reducing flavoprotein and its possible function in cyclic electron transport, the regulation by protons of electron transport, and the redox system of ascorbate and monodehydroascorbate (the ascorbate free radical). The function of this system in providing ATP in the stoichiometric amount needed for carbon assimilation, and the regulation of the alternative transfer of electrons to NADP and to the ascorbate free radical were among the achievements of my collaborators and myself. Specifically, the early conviction that cyclic phosphorylation was essential part in photosynthesis was shattered as far as higher plants are concerned, and replaced by a modified Mehler reaction providing additional ATP to run the Calvin cycle. The situation seems to be different in unicellular green algae, where quantitatively much larger changes of the relative size of Photosystem (PS) I and PS II antennae during the so-called 'state' transitions have been reported, and these seem to be associated with a high activity of cyclic electron transport in state 2. Beyond the science, the friendly interactions with so many persons around the world sharing my interest in photosynthesis and in other aspects of human life have been most rewarding.

William A. Arnold discovered many phenomena in photosynthesis. In 1932, together with Robert Emerson, he provided the first experimental data that led to the concept of a large antenna and a few reaction centers (photosynthetic unit); in 1935, he obtained the minimum quantum requirement of 8–10 for the evolution of one O2 molecule; in 1951, together with Bernard L. Strehler, he discovered delayed fluorescence (also known as delayed light emission) in photosynthetic systems; and in 1956, together with Helen Sherwood, he discovered thermoluminescence in plants. He is also known for providing a This historical paper was read, edited and approved for publication in the Historical Corner of Photosynthesis Research by Elizabeth Arnold and Helen Herron, daughters of William A. Arnold, Jane F. Hill, a historian of science, and George C. Papageorgiou, an expert on Photosynthesis and Related Processes. Papageorgiou wrote ‘‘I really enjoyed reading this ‘‘Historical Corner’ ’ paper by Choules ...
We provide here a News Report on the 2014 Gordon Research Conference on Photosynthesis, with the subtitle ‘‘From Evolution of Fundamental Mechanisms to Radical Re-Engineering.’’ It was held at Mount Snow Resort, West Dover, Vermont, during August 10–15, 2014. After the formal sessions ended, four young scientists (Ute Ambruster of USA; Han Bao of USA; Nicoletta Liguori of the Netherlands; and Anat Shperberg-Avni of Israel) were recognized for their research; they each received a book from one of us (G) in memory of Colin A. Wraight (1945–2014), a brilliant and admired scientist who had been very active in the bioenergetics field in general and in past Gordon Conferences in particular, having chaired the 1988 Gordon Conference on Photosynthesis. (See an article on Wraight by one of us (Govindjee) at http://www.life. illinois.edu/plantbio/Features/ColinWraight/ColinWraight. html.)
