Global Anti-GlnA, Anti-Rubisco, Anti-PsbA (D1) Antibodies Available
(posted 26 December 2001)

Polyclonal antibodies have been developed that recognize peptide targets found in all known GlnA proteins (glutamine synthetase), RbcL Type I (ribulose bis-phosphate carboxylase; rubisco), and PsbA/D1 (Photosystem II core protein). The antibodies are commercially available from AgriSera AB. Using antibodies with broad taxonomic ranges may facilitate tracking changes in photosynthesis and metabolism in a wide range of samples, including uncharacterized cyanobacteria and mixed phytoplankton samples. More global antibodies are under development including Anti-NirB (nitrite reductase) and Anti-NifH (nitrogenase).

Aquatic Microbial Ecology Meeting
(posted 22 October 2001)

The 8th Symposium on Aquatic Microbial Ecology will be held 25 Oct to 30 Oct, 2002, in Taormina (Messina), Italy. The web site for the symposium (http://www.same-8.it/) already has posted a registration form. The scientific program ranges from classical ecology (food-chains, biogeochemical cycles, structure and role of the microbial communities in the aquatic systems) to molecular topics (mechanisms of adaptation to environmental changes, quorum sensing). There is also a session dedicated to the possible application of aquatic microorganisms (use of microorganisms for bioremediation, search for bioactive products).

Cyanobacterial/Algal Phylogeny and Evolution Reviewed
(posted 30 April 2001)

Three reviews on the phylogeny of cyanobacteria and algae have recently appeared in the annual series Progress in Botany (published by Springer-Verlag, Berlin). Hans Preisig reviewed the systematics and evolution of cyanobacteria [Preisig HR (2000) Progress in Botany 61: 285-299] and earlier covered similar ground with algae [Preisig HR (1999) Progress in Botany 60: 369-412]. These reports focus on the years 1990-1998, during which hundreds or thousands of publications on the systematics and evolution of cyanobacteria or algae, respectively. Special reference is given to the phylogenetic relationships within the different groups of algae and cyanobacteria and the taxonomic implications of the new results. A third review [Melkonian M (2001) Progress in Botany 62:340-382] considers genomic aspects and the phylogeny of organelles such as plastids, mitochondria, and nucleomorphs in algae.

A Key for the Identification of Cyanobacteria of the British Isles

Eutrophication of bodies of water is as much a problem in the British Isles as it is in many other places. Cyanobacterial blooms and scums are not only a symptom of eutrophication, but many strains produce potent toxins that can harm fish, livestock, pets, and humans. The need to identify cyanobacteria growing in bodies of water and assess the risk they entail has inspired the British Environment Agency in collaboration with Brian Whitton (University of Durham) to develop a taxonomic key that may enable those confronting blooms to see what their up against.

The key aids in the identification of any of 320 species in 65 genera of freshwater, terrestrial and marine blue-green algae found in the British Isles. It contains many illustrations and color images together with species descriptions. The CD-ROM format offers an interactive interface, where the user is asked questions and from the answers given descriptions and images of candidate species.

FRANCOISE JOSET has retired from her position at University of Marseille, after a career of increasing our understanding of areas including carbon uptake and salt stress. She also managed to find time to write what has been a standard text in bacterial genetics. She plans to reinvent her life, rediscovering paths left unattended owing to the pressures of the moment. Cyanobacteria will still grow in Marseille, as her former lab is now inhabited by another cyanobacteriologist, Cheng-Cai Zhang. (26/xii/01)

Chris Bauer

Chris Bauer, who suffered from limb-girdling muscular dystrophy, died in Houston 21 May 2001. According to Henry Epstein, with whom Chris worked for several years on nematode myosin and dystrophin, he passed away in his sleep, peacefully. In Chicago, we are still processing data from the hundreds of experiments Chris did for his thesis. Chris was an eclectic and tenacious scientist, always challenging the world of nature. He was as brave as a man can be, refusing assistance until it became impossible to live without it. He even volunteered during the summers to work at a camp where the kids were in worse shape than he was. The world is a poorer place without him.

Jan Amesz

With grief and sadness we inform you that on Monday, January 29, 2001, Prof.Dr. Jan Amesz passed away unexpectedly.

For more than 40 years Jan has been working in the Department of Biophysics at the University of Leiden. Over those years he has contributed greatly to the development of the Department and its international stature. Strongly driven in his commitment to science, Jan also had a keen interest in and felt responsibility for the daily course of affairs in the Department. He was very supportive and inspirational to his students, and they will remember with gratitude the tireless efforts and energy which he put forth in the interpretation of experimental data and in transforming these into manuscripts and theses.

Even after his retirement Jan wished to remain associated with the Biophysics Department and scientific activities. Unfortunately, his involvement has abruptly ended. We will miss the great expertise and knowledge which he contributed, and especially we will miss him as a colleague and a friend who was open for discussions and always had a valuable word of advice. We are very grateful to Jan for the dedication and efforts in the many years over which he provided leadership to our Department.
