The Web

For those of you who have experienced the World Wide Web, no explanation is necessary. For those of you who have not, no explanation is possible... nonetheless, here's an attempt. Imagine an encyclopedia that is continuously and instantaneously being updated by its readers strewn throughout the world. Each entry, or homepage, is a collection of pertinent text, graphic images, and sounds deemed appropriate by its creator, plus instant connections to other entries. You can visit a homepage and consume or even download items of interest or you can surf from connection to connection, often finding yourself far afield from where you started.

There are already several homepages of interest to cyanobacteriologists. Ben Long (La Trobe U.) is perhaps furthest along in a homepage devoted to cyanobacteriology. The focus of his homepage is TOXIC CYANOBACTERIA and currently includes:

1. A short introduction to microcystins, including diagrams

2. A description of Microcystis aeruginosa,including a scanning EM picture

3. Preliminary information on protein phosphatases

4. Information on Cyano-Tox, a discussion group on toxic cyanobacteria and their toxins

5. Access to Cyanonews, including back issues and the Directory of Cyanobacteriologists

6. Links to some other relevant homepages

The site is still under construction (and probably always will be), and Ben is anxious to receive feedback, submissions, and suggestions for additions. In particular, he would like contributions that update or correct any errors on the existing page and information from those who work on other cyanobacterial toxins (or secondary metabolites). Even contributions that are only tangentially related to toxic cyanobacteria are welcome, as the more information available on any topic will make the page much more useful. Some people have indicated eagerness to see pictures of their favorite cyanos. Any pictures (in GIF format) are welcome! Ben is also interested to make contact with someone well versed in HTML, the language of making web pages. The page may also be used as a bulletin board for up and coming events. Please send them in!

Mark Schneegurt (Purdue U.) is initiating a GENERAL CYANOBACTERIOLOGY web site, which should be up and running the middle of January, 1996. It will eventually contain a searchable bibliography of cyanobacteria-related articles. Anyone with items that would be of interest -- e.g., lists of gene names, sequenced genes, etc. Mark is especially interested in protocols and teaching materials. Items can be sent to him by E-mail or FTP.

The University of Arizona, Dept. of Chemistry and Biochemistry has put together a site devoted to matters of PHOTOSYNTHESIS. WEB: http://aspin.asu.edu/provider/photosyn/


The University of Antwerp runs a site that collects RRNA SEQUENCES. WEB: http://www-rrna.uia.ac.be/


Matters Arising

A summer course on the ORGANIZATION AND ASSEMBLY OF THE PHOTOSYNTHETIC APPARATUS will be held 12-23 May 1996 at the Weizmann Institute, Rehovot, Israel, open to graduate and post-graduate students. The course is intended to aid students from either a biochemical or biophysical background comprehend the current state of the field and its methodological basis. The registration fee of $200 will cover full board and tuition. Since there is a limitation of 25 participants only, those interested should apply in writing as soon as possible. The application should include a resume of studies, personal details (full name, nationality, date of birth, gender) and address details (mailing address, fax, e-mail etc.). Include also a brief (not more than 1 page) resume of present work, list of publications (if available), and letters of recommendation (preferably from at least two mentors).

A book entitled Detection Methods for Cyanobacterial Toxins is now available from CRC Press. The book is based on presentations at a meeting of the same name held in Bath, September 1993. The 202 page book, edited by Geoff Codd and others sells for U.S.$89.95.

Some readers may not be aware that The Molecular Biology of Cyanobacteria, edited by Don Bryant and recently reviewed [Haselkorn R (1995) Science 269:1121], is just the first volume of a series, entitled ADVANCES IN PHOTOSYNTHESIS. The series, from Kluwer Academic Publishers, is intended to provide a multidisciplinary approach to the topic, spanning the range from macromolecular structure to whole plant physiology. Volume 2 was recently released: Anoxygenic Photosynthetic Bacteria, edited by Robert Blankenship, Michael Madigan, and Carl Bauer. Future volumes include:

Oxygenic Photosynthesis: The Light Reactions (Don Ort and Charles Yocum)

Environmental Stress and Photosynthesis (Neil Baker)

Physical Methods in Photosynthesis Research (Jan Amesz and Arnold Hoff)

Lipids in Photosynthesis: Structure, Function and Genetics (Paul Siegenthaler and Norio Murata)

If you have an idea for an additional volume, then by all means pass it on to Govindjee, the series editor, at:

The Jacques Monod Conference on Synthesis and Function of Photosynthetic Complexes will be held in Aussois, France, 25-29 March, 1996. Four major themes will be discussed: Expression of genes involved in photosynthesis, transport and targeting of chloroplast proteins, structure of photosynthetic complexes, and function of photosynthetic components. Interested scientists may apply by sending their CV, a one page summary of their research interests, and a list of their most relevant publications to:
